The ignominious end of HMS Caledonia: the thread about how the Navy’s longest ship ended up as scrap metal on the Forth seabed

Q. What was the largest ship in the Royal Navy at the outbreak of WW2?

A. As any respectable naval anorak knows, it was the 47,000t, 860ft long battleship HMS Hood, the “Mighty Hood“, pride of the fleet and largest warship afloat. Right? Or… was it the Bismarck?

No, the largest ship in the Royal Navy at the outbreak of WW2 was the 56,500t, 956-ft long training ship HMS Caledonia; until 1936 the Cunard-White Star liner RMS Majestic, which until 1922 had been the Hamburg-Amerika liner SS Bismarck. Until 1935, the largest ship in the world

The Bismarck was the 3rd and largest of three Hamburg-Amerika liners built immediately prior to WW1; the others were the Vaterland and Imperator. They were ordered to reclaim dominance and German national pride in the Transatlantic liner stakes from the British Cunard and White Star liners. They were to do this by being both the largest and grandest liners afloat. Bismarck was the last of the trio but before she was laid down, the Hamburg-Amerika line found out that the new Cunard liner Aquitania was to be longer than her, so they hastily rejigged the design to add an extra 6 feet on. They needn’t had bothered, they had made been misinformed and Aquitania actually ended up being 50ft shorter than Bismarck.

It was too late to change the design however and it was too late for her sister Imperator, which had been given the most embarrassingly awful nose job to lengthen her by the vainglorious addition of a massive bronze eagle figurehead which was meant to make her 1ft longer than Aquitania. Fortunately for her appearance this partially fell off during Atlantic storms within a year, and was removed.

Bismarck was launched in June 1914 by a granddaughter of the Iron Chancellor, but this ceremony was jinxed when she fluffed the swinging of the champagne bottle and it only broke on the second attempt: none other than Kaiser Wilhelm II stepped in to give it his best swing. The outbreak of war found her without a purpose, and construction ground to a halt beyond maintenance work. During the war she was stripped of valuable components, wiring and piping and all her brass and copper. The incomplete hulk was ceded to Britain under the Treaty of Versailles as reparations for the loss of the White Star liner Britannic (sister of Titanic), which had struck a German mine and sunk in 1916 while serving as a hospital ship. This was the largest ship lost in the war, but although she sank in just 55 minutes, all but 30 souls on board were saved. Her sister Imperator went to Cunard as a replacement for the Lusitania, the ill-fated liner whose sinking had outraged America and helped drag that nation into the war against Germany.

White Star sent representatives and shipyard engineers from Harland & Wolff in Belfast to Hamburg to supervise completion of their new possession. The whole ship needed re-wiring, and a mysterious fire that damaged her during completion and which the British put down to sabotage by the German workers was probably an electrical fault: this would be a recurrent theme. She completed in March 1922 and White Star officers were sent to supervise her trials by officers and men of Hamburg-Amerika line. This was marred by briefly running aground, but after a week she was accepted and handed over. Her German name was painted out and replaced with Majestic.

A White Star crew arrived and sailed her to Southampton, during which time they repainted her funnels into company colours. She arrived exactly 10 years to the day that the Titanic had departed on her ill-fated maiden voyage. Not only the largest in the world, she was arguably the most opulent, designed by the French architect Charles Mewès. Her German builders had trunked the boiler uptakes around the ships sides (rather than through the centre), to allow for huge, uninterrupted interior spaces, and spared no expense on the specification

Despite being a foreigner in a time when ocean liners were a symbol of national prestige, she was made White Star flagship and was the pride of the fleet. Her first official duties were to be inspected by King George V and Queen Mary, before heading for New York. She settled down to a glamorous 1920s career on the Atlantic, but one that was always marred by the occasional spontaneous fire in her electrical system, and growing cracks in her decks (which grew to 100ft long) as a result of the lengthening job.

The Depression hit the Transatlantic liners hard, already struggling from a downturn in migrating passengers, and in White Star’s case, poor corporate management. The Majestic frequently found herself on “booze cruises” from a very dry and thirsty Prohibition-era USA to help pay her huge running costs. But the cracks grew bigger, the electrical fires got more frequent and the finances grew ever worse. Cunard and White Star line merged in 1934 in a government-sponsored deal. The new company had too many liners and the older ones began to be disposed of; Majestic survived the initial chop, but her card was marked.

With the new company flagship Queen Mary under construction, Cunard-White Star made to dispose of the sister ship Berengaria, which was older and more prone to fires, but the larger Majestic had higher running costs so in 1936 was taken out of service instead.

She quietly sailed her last voyage in February that year and disappeared from the schedules without any announcement on her future. In May she was bought by Thomas Ward of Inverkeithing for £115k (c. £6.6m in 2023), the scrapyard where many a liner and battleship ended its days.

Announcement of the last sailing of the Majestic, Birmingham Gazette, 14th February 1936

Majestic was taken into dock at Southampton to have her funnels and masts lowered to allow her to sneak beneath the Forth Bridge, but there was a snag – the minor matter of fine legal print of the Treaty of Versailles. Bismarck had been handed over as a prize of war as compensation to White Star, but the terms did not allow the new owner to sell her. Instead, the Royal Navy stepped in and took possession, and “gave” Wards 24 old destroyers of equivalent scrap value in return. Everyone was happy. The lawyers were happy. Cunard-White Star got paid by Wards, Wards got the scrap they had paid for and the Royal Navy got what had been – until 6 months previous – the largest ship in the world, for the price of only a few old rusty relics.

The great liner was now taken in for conversion to an enormous training ship, with capacity for 1500 trainee boys and 500 officer apprentices. Her luxurious fittings – apart from the swimming pool – were stripped out, and the vast interior converted to spartan classrooms. Where once her passengers slept in the most luxurious cabins afloat, the new occupants would sling hammocks from the roof beams in time-honoured Royal Navy tradition. In April 1937 she made her last sea voyage, to Rosyth on the Firth of Forth.

The Majestic passing under the Forth Bridge in April 1937 en route to commissioning as into the Royal Navy

On arrival, she commissioned as HMS Caledonia, named after the Victorian training ship that had once served on the Forth under that name. Her job was to train the boys and young men who would fill the ranks of the expanding Royal Navy in the run up to the inevitable war. By the end of the year there were 1,000 trainees aboard.

The training ship HMS Caledonia on the Forth in 1898, an old battleship built in 1810 as HMS Impregnable.

The new Caledonia only had an expected lifespan of 4 years, she was to plug the gaps until permanent shore facilities could take over; but she didn’t even make this. On the outbreak of war there was a panic that the Luftwaffe would target her for a revenge sinking. This was not without reason and the first air raids over the United Kingdom during the war soon followed over the Forth with the Royal Navy and Rosyth being the target. And so the trainee boys onboard were packed off to safety in the Isle of Man, the officer apprentices were sent ashore at Rosyth, and the great ship was floated out into the Forth and pumped full of water so she would settle on the sea bed at low tide (therefore couldn’t be “sunk”), to await her fate, or another use.

However the proud old ship had other ideas. Just 26 days after war was declared and a full 17 days before the Luftwaffe arrived over the Forth, she set herself on fire and burnt out, settling on to the bed of the Firth. Her shonky electrical system had the last laugh. With the country now at war with Germany, the niceties of previous treaties could be overlooked, and she was sold to Wards of Inverkeithing – again, for mining as a strategic reserve of scrap iron. She was demolished in situ from 1940-43.

In July 1943, what remained of the hull was patched up and floated around the corner to Inverkeithing, for beaching and final break-up by Wards. This was completed in 1944, her name transferred to a shore station at Oban.

After the war, the name was relocated back to Rosyth, where it was a shore training establishment until 1985. It was rehabilitated again at Rosyth in 1996, where it remains to this day, the Navy’s HQ in Scotland and Northern Ireland. The HMS Caledonia which was once the liner RMS Majestic remains the longest ship to have ever commissioned into the Royal Navy, a full 24ft longer than the modern Queen Elizabeth aircraft carriers. With her loss in 1939, the battleship HMS Hood would regain her crown as the largest ship in the Navy. In a sardonic twist of fate, Hood would be sunk in May 1941 by a German ship named Bismarck – with great loss of life.

A day of firsts; the thread about the start of the air war over Britain above the Firth of Forth

This thread was originally written and published in July 2023.

On September 3rd 1939, the United Kingdom declared war on Germany, drawing the country into what would become the Second World War. This early period of the war is sometimes called the “Phoney War”, on account of the relatively limited military activity between France, Germany and Britain on the Western Front. However on Monday 16th October 1939, the air war over Britain commenced over the Firth of Forth as German bombers made their first air raid on the country of the war and the RAF squadrons defending Edinburgh went immediately to war.

603 (City of Edinburgh) Squadron – an auxiliary squadron defending its home city from RAF Turnhouse – claimed the first German aircraft to be shot down by an RAF fighter over British territory in WW2 on that very day. At about 14:45, Red Section under Flt. Lt. “Patsy” Gifford fatally damaged a Ju-88 bomber near Cockenzie. The German aircraft, from squadron KG30, crashed into the Forth 4 miles offshore. The Cockenzie fishing boat Dayspring, skippered by John Dickson, rescued the crew. They admitted that they were reluctant at first to do so, but they were sailors foremost and overcame their misgivings to help those in peril on the sea.

Rear gunner OGefr. Kramer had been killed before the plane crashed and was never found, but pilot OLt. Hans Storp and crewmen Hugo Rohnke and Hans Georg Heilscher were saved and sent to the military hospital at Edinburgh Castle, the first German military prisoners in Britain of WW2. The grateful Storp gave his gold ring to John Dickson in thanks for his life.

Earlier that morning, at 09:30, the “Chain Home” radar station at Drone Hill in Berwick shire had identified two enemy aircraft approaching over the North Sea. At 10:21, Flt. Lt. George Pinkerton of 602 (City of Glasgow) Squadron became the first RAF fighter pilot to attack a German aircraft over Britain when his Spitfire engaged and damaged a He-111 bomber over the Isle of May. This aircraft – one of two from squadron KG26 – had been on a reconnaissance flight to photograph the naval dockyard at Rosyth and was chased east out to sea where it evaded its pursuers, returning safely home. 602 Squadron had been redeployed eastwards to defend Edinburgh and the Forth and had been based out of RAF Drem in East Lothian for just 3 days.

A confused game of cat and mouse now commenced between the RAF and Luftwaffe all along the East Coast of Scotland for much of the morning and early afternoon as attempts were made to intercept sporadic German incursions. The radar sets failed to work properly and broke down, phantom raiders were reported by the public and the ground controllers got their calculations back to front and sent the defending fighters in the wrong directions.

That afternoon the weather was good – clear skies with only broken cloud. At 14:20, the Royal Observer Corps, trained ground spotters whose job was to identify and report enemy aircraft over land, confirmed the presence of Ju-88 bombers in East Lothian. These were 12 aircraft commanded by Haupt. Helmuth Pohle of squadron KG30 and had been sent on a mission to attack the Royal Navy at Rosyth, based on the reports from the morning reconnaissance flight that George Pinkerton and 602 Squadron had intercepted. Once again, those Spitfires were scrambled to meet the raiders. At 14:27, the anti aircraft battery at Dalmeny reported the bombers flying up the Forth. The attackers had been forbidden to attack the Dockyard itself for fear of civilian casualties, so aimed for the ships anchored in the Firth. While the gunners frantically phoned for permission to open fire, the bombs began to fall.

The first wave of attackers targeted the cruiser HMS Southampton. At 14:35, the 500kg bombs fell around the ship but missed; however two of her boats that had been anchored alongside, including the Admiral’s personal barge, were sunk. At 14:38 – three minutes after the start of the attack – the orders for the defenders to open fire were given and every anti-aircraft gun on land and on ships that could be brought to bare opened up. At the same time, the next wave of attackers, those led by OLt. Hans Storp, arrived. They approached from the south over Threipmuir Reservoir and commenced their bombing run.

By now, both 602 (City of Glasgow) and 603 (City of Edinburgh) squadrons were in the air. Yellow Section of 603 attacked Storp and put his port engine out of action. The plane limped towards East Lothian out to sea, in a futile attempt to escape, which was where Red Section under Patsy Gifford brought it down. The victorious 603 were now ordered to return to Turnhouse to re-arm and re-fuel, leaving the defence in the hands of 602 Squadron. Blue Section, under George Pinkerton, spotted the aircraft of Helmuth Pohle over Inverkeithing and gave chase through the broken cloud. Pinkerton and his wing-man Archie McKellar attacked, killing two of the German machine’s crew and incapacitating both its engines. It headed for the sea near Crail and ditched three miles off of Fife Ness. The time was somewhere between 14:45 and 14:55, the Observer Corps putting the crash at the latter time, but McKellar and Pinkerton are credited with gaining the “first kill” before Patsy Gifford in some chronologies.

The events of October 16th had not yet concluded however. About 25 minutes after Pohle’s machine crashed, another Ju-88 bomber appeared over the outer reaches of the Forth. It had escaped interception up to this point as the ground observers had initially thought it to be a friendly Bristol Blenheim (an easy mistake, as the two were somewhat similar and the Ju-88 was a brand new aircraft and almost totally unseen by British eyes this early in the war). It found the destroyer HMS Mohawk off of the fishing village of Elie & Earlsferry and attacked; dropping its bombs and firing its machine guns at the ship.

By the time it was chased off by one of 602 Squadron’s Spitfires, 13 men including First Lieutenant E. J. Shea had been killed. Her captain, Commander Richard Jolly, was fatally wounded but refused to abandon his post and brought his ship safely back to Rosyth before dying a few hours later. In total 16 men from the Mohawk would lose their lives that day.

The last of the raiders that day appeared in ones and twos across the Lothians around 16:00 and were chased across the Forth, RAF Turnhouse, Edinburgh, Leith and Portobello by the Spitfires of 603 Squadron, but to no avail. Minor injuries were caused across the city from broken glass as bullets fired in the sky came down to earth and painter Joe McLuskie, working on a house in Abercorn Terrace, Portobello, was hit in the stomach and had to undergo emergency surgery in Leith Hospital. The raid had also claimed its first animal victim of the air war over Britain when Lady, a spaniel belonging to Mrs Mercer of Alma Street in Inverkeithing, was struck by shrapnel from falling “friendly” anti-aircraft shells and had to be put down as a result. The noise of the bombs and guns had panicked the animal and it had run off into the street.

Off of Crail, a fishing boat hauled four ditched German airmen from the sea. Crewmen Kurt Seydel and August Schleicher were already dead, Kurt Naake was mortally wounded and would not survive, leaving pilot Helmuth Pohle – nursing a broken jaw – as the sole survivor. He was sent to the naval hospital in Port Edgar. The bodies of Seydel and Schleicher lay in state at St. Phillip’s Church in Portobello, their coffins draped in Swastika flags, and were buried with military honours observed by a respectful turnout of locals at Portobello Cemetery. The proceedings were led by Henry Steel, the Lord Provost of Edinburgh, and many men from both 602 and 603 Squadrons were in attendance with the pipe band of 603 providing a musical lament. The pair were re-interred in a German military cemetery in England after the war.

Both Patsy Gifford and George Pinkerton would receive the Distinguished Flying Cross award for their efforts that day. Gifford, a reservist who was in peacetime a lawyer and town councillor from Castle Douglas, was sent to command 3 Squadron RAF in November 1939. He was shot down and killed over Belgium in May 1940.

Gifford and Pinkerton both have claims to their “first”. However neither claimed either the first British or first RAF aerial victories of the war. On September 26th 1939, Lt. Cdr. Bruce S. McEwen of 803 Squadron Fleet Air Arm and flying from HMS Ark Royal (therefore a Royal Navy aviator and not in the RAF) shot down a German Do-18 flying boat over the North Sea off Norway, the first British aerial victory of the way. The below photo was taken by the destroyer HMS Somali when they rescued its crew.

Another Do-18 would become the first German aircraft brought down by an RAF aircraft flying from the British mainland, was claimed by a Lockheed Hudson patrol aircraft of 224 Squadron Coastal Command out of RAF Leuchars on 8th October. The Hudson, actually a modified American airliner and intended to be a bomber and reconnaissance aircraft, proved to have a surprising capability as a long range fighter in the early part of the war.

And two weeks after 602 Squadron’s Pinkerton and McKellar brought Helmuth Pohle’s war to a premature end off of Crail, Archie McKellar shot down an He-111 bomber of squadron KG26, flown by Uffz. Kurt Lehmkuhl over East Lothian. This was the first RAF victory that brought down a plane over land, the machine making a crash landing in the Lammermuir hills near Humbie.

Another He-111 was shot down by 602 Squadron out of RAF Drem on February 9th 1940, with Squadron Leader Douglas Farquar bringing it down in a field just outside North Berwick.

This was the first chance for British intelligence to get a close up look of such a machine in a flyable condition and it was therefore partially dismantled and towed away for onwards transport to the Boffins down south. The plane was put back together, repaired, and commissioned into the RAF as part of the “Rafwaffe” of captured machines. Here it is seen going down Dirleton Avenue in North Berwick to the bemusement of onlookers.

Remarkably, there’s a colour cine film of it going down Musselburgh High Street, exciting much local interest, on its way to RAF Turnhouse.

Hans Storp’s Ju-88 would suffer the misfortune of being the first pilot and aircraft to be shot down twice in the war, when in December 1939 a re-enactment of his last flight took place for the propaganda film “Squadron 992“. An RAF Bristol Blenheim (which the observers had confused with the German Ju-88 back in October) stood in for the German machine on this occasion. The Cockenzie fisherman John Dickson, his crew, and their boat the Dayspring reprised their roles from that day and played themselves for the cameras.

Last voyage of the battlecruiser “Moltke”: the thread about how a German warship almost destroyed the Forth Bridge

On a recent (2022) trip to Orkney we visited the excellent and newly refurbished Scapa Flow museum and I bought a fascinating book on the subject of the internment, scuttling and salvage of the German Hocheseeflotte – the Imperial German Navy’s “High Seas Fleet” , after WW1. (The author, Dan Van Der Vat, is very readable, being a journalist by trade.) So naturally I’ve managed to find an exciting and little known of local history angle to this.

The SMS Moltke (Seiner Majestät Schiff, His Majesty’s Ship) was a 25,000 ton battlecruiser of the Imperial German Navy. She was 612 feet long, 96.5 feet wide, could make 25.5 knots on the 51,000 horsepower produced by her engines and was armed with ten 11 inch guns in five turrets. Battlecruisers were the pride of contemporary fleets, as well armed as the main battleships but able to reach the sort of speeds usually reserved for smaller ships. Big, well armed and fast, Moltke was every bit the equal for her Royal Navy equivalents.

Moltke in New York, 1912

At the end of the war the Hocheseeflotte was still largely materially intact, but organisation and discipline was another matter. It was forced under the terms of Armistice by the Allies into a humiliating internment under the watchful eye of the Royal Navy. It had been hoped by the Germans that the fleet would be dispersed to neutral ports but instead it ended up imprisoned in the bleak confines of Scapa Flow, the principal wartime anchorage of the Royal Navy’s Grand Fleet. Its remaining ships arrived at Scapa after a rendezvous with the Grand Fleet in the Firth of Forth, from where it was escorted into a miserable internment.

The German Fleet at Anchor off Inchkeith, Firth of Forth: After the Surrender, IWM ART 1926

The German ships were disarmed and made incapable of war or even escape, but legally they remained the property of the German state. They were supplied by German provision ships sent by the German government from German ports. Although their crews were not officially prisoners, they were not allowed to leave the confines of their ships and no British personnel were allowed aboard apart from small official delegations pertaining to the administrative niceties of exile. As the signing of the Treaty of Versailles approached, the German Admiral in charge at Scapa – Ludwig Von Reuter – found himself in an impossible position.

Vizeadmiral Hans Hermann Ludwig von Reuter

Von Reuter was caught between the national honour of the Prussian officer class; his mutinous and non-compliant crews; British belligerence and overwhelming Allied political pressure. His fear, not without reasonable, was that the British would try and seize the German fleet on the signing of the treaty. He gathered around him a select circle of loyal officers and right under the nose of the watchful Royal Navy and his own suspicious and resentful sailors, managed to organise a mass scuttling of almost his entire fleet.

The battleship Bayern sinking in Scapa Flow, the same image as used on the cover of Dan Van Der Vat’s book.

On 21st June 1919 the conspirators managed to scuttle fifteen of the sixteen battleships and battlecruisers, five of the eight fleet cruisers and thirty-two of the fifty destroyers at Scapa. The cream of the German Navy was turned into the half a million tons of scrap metal on the seabed in a matter of hours. Publicly the British were furious (the Royal Navy doubly so as it had been totally humiliated), but Von Reuter had actually done everyone involved a favour and simplified negotiations over the fate of the fleet – If the German Navy lay at the bottom of Scapa Flow then nobody could have it: not the British, the Germans, the French, the Americans or even the Italians.

Seydlitz on her side in Scapa Flow

Scapa Flow was now littered with over fifty German wrecks in various states of submersion, posing quite the navigation hazard – as demonstrated ably by the government whaler Ramna which got stuck fast on top of the capsized hull of the Moltke. The world soon moved on from the scuttling as shattered countries sought to begin rebuilding themselves post war.

The Admiralty whaler Ramna, high and dry on the Moltke’s partially submerged hull

Enterprising locals (often unofficially) stripped what they could access above waterline for scrap until an enterprising Shetland shipowner and councillor – J. W. Roberston – proved that you could salvage wrecks from underwater and brought a number of torpedo boats ashore for their scrap value. Enter now stage left the enterprising, irrepressible and energetic figure of Ernest Frank Guelph Cox. Cox was a self made engineer and metal dealer from the Midlands who had the vision to believe he could access and salvage the five hundred thousand tons of best German steel located at the bottom of Scapa Flow. Now that the price of scrap metal had started to rise after the immediate postwar slump, his backers believed that it would now be financially worthwhile.

Ernest F. Cox, from the book Cox’s Navy by Tony Booth

Cox’s business partner in his firm – Cox & Danks – was his cousin, the capital behind the operation. Together they bought the rights to salvage the Hocheseeflotte from the Admiralty and set to work at Scapa in the mid 1920s. Cox had the foresight to hire Tom McKenzie, a Glaswegian naval salvage diver who would pretty much write the book on naval salvage diving.

Tom McKenzie

Although all involved were practical, skilled and experienced men, they were starting from almost nothing and had to largely invent, improvise and improve all the required techniques for marine salvage on this scale. Overcoming setback after setback, they were driven along by Cox’s indefatigable determination and Danks’ deep pockets. They made rapid progress and the first torpedo boat – V70 – was raised after less than 2 months work in 1924. Moving on to the next boat and then the next one after that, they honed their techniques and were soon raising ships at a rapid rate. Within two years, all twenty six torpedo boats that Cox had the rights to take had been raised.

Salvaging a destroyer

Cox now turned his attention to the big ships on the bottom, the battleships and battlecruisers. In May 1926 he started on the SMS Hindenburg, but even though she reached the surface the operation proved a disaster and she had to be quickly resunk. The precarious situation of the salvagers at Scapa was saved by the discovery of huge stocks of coal in the bunkers of SMS Seydlitz; it was found these could be accessed and “mined” from the surface and this free source of fuel tided the operations over. Cox now set his sights on the Moltke. The basic technique was relatively simple. Divers were sent down to plug the holes in the hull and it was pumped full of compressed air, displacing the water aboard. As it leaked and bubbled out through the holes that had been missed, these two were plugged. Eventually air could be pumped in quicker than it escaped and slowly the hull would start to float.

I say relatively, in practice it was tremendously difficult and verging on the impossible. They were working at – or beyond – the limits of contemporary diving skills and technology. Conditions were harsh and the environment of Scapa Flow was unforgiving as any British sailor ever sent there would attest, but Cox’ determination and McKenzie’s skill drove them forwards. The Germans had efficiently and effectively wrecked the watertight integrity of the ships’ inner bulkheads so before they could be raised in a controlled manner, divers had to go in and restore it by welding and plugging any gaps they could find. To make this possible, airlocks – like huge submarine chimneys – were built down into each compartment. From these, divers could access the innards and get to work under intense air pressure, working upside down on ships encased in marine slime, often in complete darkness.

Cox was a bit of a showman, always on site and always hands on. His men respected him and the press loved him. He made sure the latter were around whenever anything interesting was happening. The Scotsman filed almost weekly progress reports on the salvage of the Moltke.

• October 21, 1926. Compressed air pumping operations commence on the hull of the Moltke.
• December 10, 1926. Moltke is rising unevenly and the divers are forced to sink her in case she is caught by the winter gales.
• Feb. 15, 1927. Work restarts after winter storms, the first airlock is fitted and almost 100 men are at work on the Moltke.
• Feb. 24, 1927. The difficulties are described of working in a 15PSI atmosphere where cutting torches burn up the oxygen as fast as it can be pumped in
• May 30, 1927. Work resumes again after 2 months of gales. A disaster is narrowly avoided when the wrong valve is closed and compressed air rushes through the ship from stern to bow, blowing the 16 divers at work inside through the ship with it.
• June 13, 1927. Cox has the Pathé newsreel men on site to witness the triumph of the Moltke breaching the surface in a controlled manner and refloating after 8 years on the seabed.

But don’t just look at those grainy thumbnails, watch the whole clip on the Pathe website! Over the next four months the refloated Moltke was painstakingly winched towards Cox & Danks’ salvage base at Lyness on the island of Hoy, narrowly avoiding grounding on the island of Cava when one of her big 11 inch guns fouled the seabed and had to be cut free. They begin cutting her up in situ but it soon becomes obvious that the isolated shores of Scapa Flow were the wrong place to do this and made little economic sense. Cox therefore convinced the Admiralty to lease him the No. 3 Dry Dock at Rosyth Royal Dockyard, the largest and most modern in Scotland.

Dragging the upturned Moltke to Lyness

He then sold on the scrapping rights to the Alloa Shipbreaking Company, who would undertake the actual dismantling work at Rosyth, thus leaving him free to concentrate on the dark arts of salvage. But the problem still remained as to how to get the beached and upside-down hulk of Moltke 250 miles south to Rosyth. The only solution was to refloat it and tow it there – a hard enough task if it didn’t include having to transit the Pentland Firth with its infamous tidal currents, some of the fastest in the world. Undaunted, Cox set to work. The ship was lightened of thousands of tons of steel such as propellers and shafts, armour plate etc., and her hull was patched up with concrete where they had started to demolish it.

Getting Moltke ready for sea at Scapa

Refloated for the journey, two shelters were built on her “deck”, actually the upturned bottom; one with accommodation for the eight crew who would make the journey (including Cox himself), the other with enough pumps to keep her full of compressed air. Lifeboats were thoughtfully included too. By May 18th, Moltke was ready to go. Controversially at the time, both in Britain and in Germany, the three tugs that were chartered to take her on her final voyage were German, including the Seefalke – the most powerful in the world – the Posen and the Simson.

The unlikely shape of the upside down Moltke, with Simsun and Seefalke lashed to her sides. The third tug could pull from the front or stern to provide better directional control.

For good measure, on board was also one William Mowat, the coxswain of the Longhope Lifeboat, probably the only man in the world qualified to pilot the wallowing hulk out of Scapa and safely past Duncansby Head.

Despite Mowat’s presence, disaster was soon upon them when the weather got up. The three tugs could not make headway against the wind and current and Moltke started going backwards though the Pentland Firth, rolling by up to 13.5 degrees. She lost 6 feet of her precious freeboard as the compressed air bubbles within that kept her afloat leaked out due to the constant rocking and pitching motions. The pumps could not keep up and she was slowly sinking. Salvation came with the tides themselves, which inevitably turned and speedily ejected the battlecruiser and her three attendants out of the Firth.

After this literally rocky start, things calmed down and the pumps were able to refill the air bubbles and lift the hull back out of the sea again. With the tugs now making headway the close call was soon forgotten about and Cox the showman had the crew play a makeshift game of cricket on the deck for the press. I think he is the man umpiring at the back, in the pullover with his hands behind his back.

The rest of the journey to the Firth of Forth proceeded calmly and according to plan and by May 21st she was off Granton. The last manoeuvre required of the tugs was to get her safely under the Forth Bridge and into the Rosyth basin. And this is where things start to go wrong. Again.

This time it was down to petty officialdom. The Forth Pilot arrived from Granton and tried to take command. He was joined shortly afterwards by the Admiralty pilot from Rosyth. A standoff now ensued as the civil and military opposite numbers argued over who had the rights to pilot the Moltke up the Firth. Neither was willing to back down and the set to kept on going, as did the changing tide and currents of the Firth. Gradually, so to did Moltke herself, gently easing her way inevitably upstream. Before the situation could be resolved, they found themselves coming upon Inchgarvie island; the very rock on which the piers of the bridge was built. And the newsmen from Pathé were there to film it all!

One of tugs found itself grounded on Inchgarvie…

Moltke approaches Inchgarvie

The Seefalke, attached at the back and in charge of providing steerage then drifted around the wrong side of the island and had to cut the tow. Moltke was now at the mercy of the currents, with two tugs lashed to her, one being dragged along the bottom, and with no ability to manoeuvre their charge.

Seefalke stands off

Now totally out of control, Moltke spun through 90 degrees and drifted sideways down the Firth towards the bridge, dragging the helpless tugs along with her. All twenty three thousand or so tons of her was now heading broadside towards the central piers of the bridge, those which rose directly out of the water itself. All the while, trains rattled to and fro overhead with little idea what was unfolding below them.

Moltke floats down the Firth towards the bridge

If you watch the remarkable clip, you can see Moltke drifting beam-on towards the bridge as a train goes by overhead. Somebody must have been saying their prayers onboard though, as somehow the tugs lashed to Moltke‘s hull managed to position the 612 feet wide floating wrecking ball perfectly between the piers and Inchgarvie, narrowly avoiding disaster.

Safely under the bridge and back under control.

The Seefalke was now able to get a line across and bring the hulk under control, steering her gingerly towards the safety of Rosyth. The watching press were blissfully unaware how close disaster had been, the Scotsman reported “a wonderful piece of navigation and most successfully performed“. However, if you look closely at the footage, Moltke approaches the bridge stern first (with her 4 propeller supports leading the way) but passes through it bow-first (with the big notch cut out from initial breaking up leading). The big battlecruiser had done a 180 degree pirouette while passing under the bridge!

Nothing to see here!

Moltke was edged finally towards the channel into No. 3 Dry Dock but Cox couldn’t yet breathe a sigh of relief; first he has to get the ship into the dock, as his contract stipulates he won’t get paid by the Alloa Shipbreaking Co. until she is in and the dock is drained.

Moltke approaches the gate of No. 3 Dry Dock

But this last step will be no small feat – there is just a one day window on the highest spring tide to get the upside down hulk into dock. Ships usually go in the right way up of course, but the inverted Moltke is drawing 41 feet of water at her deepest, 25% more than she would otherwise, and the dock gate had a lip that reduces the depth of the water to only 38 feet! But this was Cox and he was undaunted – by an incredibly skilful act of pumping compressed air in at one end and letting it out at another, and then reversing the process, he was able to “hop” the deepest part of the ship over the dock lip and get her safely in with the gates shut.

But on the brink of final triumph, once again officialdom almost screwed everything up for Cox. With Moltke bobbing in the waters of the still flooded dock, the supervisor stepped in and disagreed about how to support the upside down ship on the dock floor. He had a point – ships didn’t normally go into dock with their pointy-bits facing down the way. There were all sorts of projections beneath the hull that might damage the critical national infrastructure that he was in charge of. Of course the Admiralty should have worked this all out with Cox before they signed over the use of the dock to him. A frantic phonecall to Whitehall couldn’t resolve things so Cox jumped straight on the first train south to thrash it out in person. Ironically to do so he first had to pass over the bridge he very nearly demolished only a few hours previously. In London an agreement was reached and he was back the next day, 28th May, to get his men to work shoring up the hull with baulks of timber.

Then dock was then slowly drained and the ship finally came to rest on the bottom. It was June 5th as the last of the water was pumped; Cox had finally won. He had raised a 23,000 ton ship from the seabed that had spent 8 years submerged – twice! -, beached it, refloated it, sailed it 250 miles through the treacherous Pentland Firth and squeezed it upside down into a dry dock into which it shouldn’t have fitted and all without demolishing one of the most important structures in the western world!

Moltke high and dry in the dock

The Alloa men could now get to work and on September 13th 1928 set about cutting up the pride of the Hocheseeflotte into thousands of tons of valuable scrap metal.

Moltke being cut up

Cox would go on to salvage every ship he could from the bottom of Scapa Flow giving up eight years later and £10,000 worse off than when he began. For all his drive and determination, his financial skills were somewhat lacking and his pioneering methods proved inefficient and just never paid back. Other Scottish businessmen, including those of Alloa Shipbreakers and salvage diver Tom Mckenzie, then formed Metal Industries Ltd to carry on were Cox left off. With more efficient, refined techniques and more sensible business practices, their venture would pay off in a big way.

The last Scapa ship raised by Metal Industries was SMS Derfflinger. Another war intervened in this venture and she spent WW2 beached and upside down, alongside the disarmed old battleship HMS Iron Duke, HQ ship at Scapa, which during WW1 had faced off against the Hocheseeflotte at the Battle of Jutland. The salvage men aboard Derfflinger would save the Iron Duke after she was nearly sunk in an air raid early in the war. Derfflinger was floated into a submersible dry dock and towed to Faslane after the war for scrapping.

One of Metal Industries’ many improvements on the salvage process was to rapidly sink the ship as soon as they had raised it, to crush and concertina the protruding superstructure up inside the hull, removing most of the underwater obstructions that plagued Cox. It is praiseworthy that the basic salvage techniques pioneered by Cox and McKenzie, and refined by Metal Industries, are still those that are in use today.

Womanning the Guns: the thread about Edinburgh and Leith’s WW2 aircraft defences

Today’s Auction House Artefact is a German Luftwaffe bombing maps centred on Edinburgh and Leith from WW2. These very maps may have been used in air raids on Edinburgh and Leith during that conflict. They have a deliberate yellow tint to make reading them under the night lighting in an aircraft easier and were printed on plastic-coated fabric to avoid creases and allow the navigator to mark on them in a wax pencil. Water, rivers, roads, railways and forests are all marked as obvious navigation markers. The map dates from 1941 and interestingly all the place names are in English – probably because German maps were basically reprints of captured or purchased British Ordnance Survey maps.

Luftwaffe bombing map of Edinburgh, Lothians and south Fife

Ziele (targets) were marked in yellow in ink that may have been luminescent so that they would appear brightly at night and account for the major docks and shipyards, airfields, military facilities and power stations along the Forth Coast. Below is my best guess at the full list of target sites (excepting the Forth Bridge, which I mistakenly overlooked).

Targets marked on the Edinburgh, Lothian & Forth map

The German Naval Command (OKM) at least bothered itself to translate some of the descriptive words on their charts into German, although again they had simply bought up sets of official and readily available Admiralty charts and reverse engineered them. The below OKM coastal chart was printed in 1938 but was already well out of date – entire interwar districts are missing; Craigentinny, Lochend and Restalrig in the east and Wardie, Granton and East Pilton in the north. The Western General Hospital is marked as Armenhaus, the translation of Poorhouse, which it had ceased to be in 1927. The fact that the railway to Leith Central Station is missing and there is no gasworks marked at Granton suggests the map predates 1900 and so was 38 years out of date at the time of issue!

Such maps show that the German military considered Edinburgh and Leith to be targets of interest. The British authorities were more than a little aware of this and were relatively well prepared when war broke out to defend the city from air attack.

The principle defence was provided by the fighter squadrons stationed at the RAF airfields at Turnhouse, to the west of the city, and Drem in East Lothian. These were the first British home air defences to be tested in the war; on 16th October 1939 a Spitfire of 603 Squadron from Turnhouse piloted by Flt. Lt. Gifford shot down a Junkers 88 bomber, one of 12 that had attacked the Royal Navy anchorages in the Forth. This was the first German aircraft of the war brought down over Britain and one of the four crew, Obergefreiter Krämer, was killed in this action. Spitfires from 602 Squadron from Drem under Flight Lt. Pinkerton brought down another bomber off of Crail, with 3 of the 4 crew being killed.

The German bombs begin to fall over the Forth Bridge from The Illustrated London News, 28th October 1939

But it wasn’t just from the skies that the city was defended, it was also protected from the ground by a ring of anti-aircraft gun batteries. This was a far cry from WW1 when Edinburgh and Leith were almost completely undefended when a Zeppelin air raid dropped 44 bombs and left 14 dead. All the anti-aircraft guns in Scotland (and Northern Ireland) were part of a Territorial Army formation called the 3rd Anti Aircraft Division, which was headquartered in Edinburgh.

Formation patch of the 3rd AA Division

There were five gun batteries around the city of Edinburgh plus a decoy site (although the one at Silverknowes may have been a decoy too and the others weren’t always armed depending on the phase of the war). The defences of Edinburgh and Leith benefited from their proximity to the Royal Navy Home Fleet’s base at Rosyth and were a component of a wider network defending the Forth anchorages, with thirteen further batteries along the coast. These defences were manned overall by 36th (Scottish) Anti-Aircraft Brigade, with Edinburgh being covered by the 94th Regiment. As the war progressed the organisational structure changed and due to a shortage of manpower mixed units were introduced by incorporating women of the Auxiliary Territorial Service (ATS) into the gun batteries.

Edinburgh Anti-Aircraft Battery designations and locations.

The gun batteries were of a standard design known as HAA sites (Heavy Anti-Aircraft) and the remaining structures of site EDG2 at Alnwickhill can still be clearly seen in aerial photography (and from the ground), underneath the equestrian paraphernalia from its modern-day use as a horse farm. The gun battery was composed of four QF (Quick Firing) guns – the pink dots – on concrete plinths with protective walls of brick and earth. These were arranged in an arc around a control bunker (white arrow). Each gun had ready-to-use ammunition lockers arranged around its inner walls, with more stored in two magazines (orange arrows) nearby. The distinctive circular feature to the north of the battery was a large calibration mattress for the site’s gunnery radar.

Most such batteries were armed with the QF 3.7-inch gun (the inches refers to the calibre, or diameter of the gun bore) that were sited at these batteries could fire an explosive shell weighing 28lbs (13kg) to an effective height of about 25,000ft (7,600m). They could shoot higher than this, but this was the maximum height to which they were able to accurately track and engage a target and was sufficient to engage all but the highest-flying enemy aircraft at this time. A photograph of one of Edinburgh’s 3.7″ guns is shown below

Each gun could fire 10-20 rounds a minute, depending on how well drilled the crews were and how physically fit they were to man-handle the heavy ammunition for any extended period of firing. The performance of the guns was therefore directly proportional to how fit the crew were and one of the principal responsibilities of battery commanders was to keep the men active. Interestingly the only other wartime photos I can find of the gun batteries around Edinburgh – at West Pilton – show physical training in progress.

The large protective shields around the guns in the background indicates that this site was actually armed with the less common QF 4.5-inch guns that were based on a Royal Navy design. They fired a heavier projectile (54lb or 24kg) to a greater height but the rate of fire was much reduced as a result, to about 8 rounds per minute.

Each gun battery was controlled by a mechanical computer known as a predictor, which would be located at the central building marked with the white arrow on the aerial photo. This box of tricks had various dials into which its operators could dial input parameters about the target and ambient conditions (measured or guessed). The internal electro-mechanical innards of the box would calculate the direction and elevation in which each gun should be pointed and the guns followed its lead; the crews just had to keep on loading them.

Notice the cable trailing from the arm in the foreground, which transmitted commands computed by the Predictor to the guns. IWM H 19092

The distance to the target and its height was calculated using a device known as a Rangefinder. The static HAA batteries used a huge 18-foot wide Barr & Stroud UB-10 device.

Hitting a tiny, fast moving target moving in three dimensions – like an aircraft – with a projectile fired by a gun mounted miles away and tens of thousands of feet below was a tall order: so tall in fact that it was actually fundamentally impossible. As a result the projectiles were not actually expected to hit their target, rather they were to explode in its vicinity, close enough to do damage. Each projectile therefore had a clockwork fuse in its nose which was set to explode when it reached its target, a setting calculated by the Predictor which sent its outputs to another machine called the Fuse Setter. As part of the loading drill, each shell would be placed nose-first into the Setter which automatically adjusted the timer, before the loader shoved the projectile into the breach of the gun. Despite all this mechanical sophistication it was still a monumentally complicated mathematical problem that could be thrown out by tiny variations in the predictor inputs, or the weather, or the ambient conditions, or the target manoeuvring. It was calculated that it would take 41 thousand rounds fired from 3.7″ guns to bring down a single aeroplane! To put this into context, the five batteries of 4 guns around Edinburgh could fire up to 320 rounds per minute at best: if you could keep that up without running out of ammunition, it would take 2.2 hours to bring down an enemy plane – which by then was halfway back home. The role of these guns therefore was less actually shooting aircraft down and more just making sure they flew high enough and took enough avoiding action to make dropping their bombs a far more challenging and less accurate task.

To improve the accuracy of the inputs to the Predictor, the HAA batteries were progressively equipped with Gun-Laying (GL) radar sets which could accurately measure the range to target with an accuracy of about 50 metres. But these early GL radar sets were primitive by even the standards of the day and used a long wavelength which was susceptible to ground interference which caused false returns. To negate this issue the ground around each radar set was “calibrated” using an enormous wire mattress; this is the circular platform visible in the aerial photograph above of Alnwickhill. A 120 metre diameter ring of ground was flattened off, with the radar antennae positioned at its the centre on a raised platform. This area was laid with a 13,000m2 mattress of ½-inch chicken wire mesh, suspended on a wooden frame at a height of 1.5m from the ground. This required 230 rolls of wire mesh, 4 feet wide by 50 yards (1.2x46m) long; 650 miles (1,050 km) of wire per site plus a further 10 miles (16km) in the supports. Such was the scale of and priority given to these calibration mattresses that they consumed the nation’s entire supply of chicken wire at the time!

The anti-aircraft defences of Edinburgh also included more exotic weaponry; there were two Z-Batteries, reinforcing the regular guns at Craigentinny and West Pilton. These sinister sounding devices were batteries of 64 twin-barelled rocket launchers that fired projectiles which deployed a 500ft long cable suspended by a parachute, with a grenade attached at the other end. The theory was that the launchers would unleash their 128 rockets across the flightpath of an oncoming enemy aircraft which would hopefully snag one or more cables and then draw the dangling grenade towards itself. These were a rather makeshift, emergency weapon to try and make up for a lack of proper weapons and were rarely effective. They did at least create a decent fireworks display to give the public the impression that they were being defended and could be manned by older members of the Home Guard up to an age limit of 60 as the rounds were much lighter than the heavy 3.7″ and 4.5″ gun rounds – the age limit for which was 40. An Edinburgh Evening News report of 25th September 1944 reports that the 101st (City of Edinburgh) Home Guard Ant-Aircraft Rocket Battery at Craigentinny had been on operational service for 820 consecutive nights, i.e. since June 1942 and was the first such battery to become operational in Scotland. At the time of reporting, each of the Edinburgh rocket batteries had fired their weapons in anger once, both on the night of 24th March 1943, and each was credited with the shooting down of an enemy aircraft, which they shared with the regular gun batteries of the city.

For night-time actions there were powerful searchlights to try and identify targets for the guns to fire at – a largely fruitless task. I have so far identified two recorded locations and suggestions of more. The first is a photograph taken in April 1942 which shows a visit to a searchlight position near Hunter’s Tryst, looking towards the Pentland Hill. The visitor is the Rev. Ronnie Selby Wright, formerly minister of the Canongate Kirk and by then senior Padre to the Army’s 52nd (Lowland) Division. He acquired the nickname “Radio Padre” after a series of popular radio broadcasts he made for the BBC.

I have also found a Home Guard sketch map in the City Libraries collection that shows a portion of the south of the city at Southhouse, with X marking the spot of a searchlight position.

Lastly I have in my possession a little book that is an account of the Home Guard activities in this district of the city during the war and it has an illustration of two searchlights being visible from the Braid Hills. This is the earliest days of the war, note the men are still wearing their LDV (Local Defence Volunteers) armbands, lack an official uniform and carry a variety of weapons.

“A Blasted Heath – 02:00”

The last fatal air raid in Edinburgh occurred on 6th August 1942. After that, there was local peace in the skies until the night of 24-25th March 1943 when there were scattered attacks across Fife and the Lothians that saw some incendiary bombs dropped harmlessly on farmland near Balerno beyond the then outskirts of the city. In “This Present Emergency: Edinburgh, the river Forth and south-east Scotland and the Second World War“, Andrew Jeffrey suggests that three German Ju-88 bombers were downed by the defences of Edinburgh during this raid, with one crashing on Hare Hill in the Pentlands and two others ending up in the Forth. Newspaper reporting at the time credits a kill each to both Z-batteries, the 102nd battery at West Pilton sharing theirs with the guns. The online database of wartime Luftwaffe losses records the loss of a plane crashing into Hare Hill outside Balerno killing pilot Fritz Foerster, gunner Willi Euler, observer Heinz Kristall and radio operator Horst Bluhm. This was the aircraft that had jettisoned its bombs in the field shortly beforehand. The other two aircraft losses that night were one that crashed on a hillside in Northumberland while being attacked by an RAF Bristol Beaufighter and another that hit a hillside near Earlston in Peeblesshire.

Through improvements in training, organisation and the technology of radar and predictors, as the war progressed the number of rounds the guns would have to fire to bring down an aircraft was reduced by an order of magnitude, to just 4,100. For Edinburgh’s defences this equated to a much more realistic 10-15 minutes of firing to get a “kill“. The last German aircraft to fly over the city likely did so on May 5th 1944, but by this time the course of the war itself had also progressed and by mid-1944 most of the UK’s heavy anti-aircraft defences, including those around Edinburgh, were redeployed to the south coast of England to counter V-1 flying bombs. The more mobile parts of Scotland’s 3rd Anti-Aircraft Division also went south and were attached to the Allied invasion forces, fighting with them across mainland Europe. By this point further technological advance had brought the number rounds required for a “kill” down by another order of magnitude to about 100.

With their guns removed the anti-aircraft defences of the city were mothballed, but we can clearly see their distinctive ground layouts in post-war aerial photography. Each gun battery is accompanied by rows of huts and buildings to house and support the personnel and all the required stores. These photographs suggest that battery EDG4 at West Pilton was fitted with radar as we can see the large circular footprint of the radar calibration mattress (the photo below of Sighthill is censored, but an uncensored version also shows the outline of the mattress). They also hint that battery EDG5 at Silverknowes was either never finished or was purely a decoy.

Although the sites were out of use by the war’s end they remained military property and a state secret. They are missing from detailed 1:1250 Ordnance Survey town plans made in 1944 and on some versions of the above aerial photos they have been censored; crudely scratched out or in the case of Alnwickhill and Sighthill, more subtly removed.

The defences of were officially stood down in 1948 and each site had a different fate after that. Sighthill was soon cleared away and the land returned to civilian use when the new industrial estate was laid out there post-war. The huts and structures of West Pilton were used as a Territorial Army (TA) training centre before being turned over to a rather grim-looking and latterly notorious housing estate. The huts at Craigentinny were also re-used, given over to emergency post-war housing as Craigentinny Camp before being returned to their pre-war use of a golf course. The camp at Alnwickhill was kept on by the army before later being used by Ferrantis at East Pilton for testing military electronics and weapons. One of its uses was for testing Bloodhound anti-aircraft missiles in the 1950s, demonstrated wonderfully by the below photograph showing such a missile pointing towards the distant Arthur’s Seat.

Along with the well-preserved structures at Alnwickhill, the dummy battery at Hilltown near The Wisp survives largely intact as it was returned to the farmer’s field from where it sprung and left too the odd cow to shelter in. From the air its layout is still unmistakably a very close copy of one of the active batteries.

Edinburgh and Leith were mercifully spared most of the horrors of aerial bombing meted out to other cities during WW2. Altogether there were 21 civilian deaths and about 210 injuries caused directly by aerial bombing during the war. Further details can be read in the thread about the air raids on Edinburgh and Leith during WW2 and the civilian loss of life they caused.
