made only passing mention of it.
By the end of 1916, despite patrols by planes, dirigibles and thousands of ships, U-boats had sunk 1,360 ships. The German U-boat service, which grew to 100 submarines, had lost only four of them to enemy action. The Admiralty stubbornly refused to inaugurate a convoy system, and produced rather bogus figures to ‘prove’ that convoys would block up the ports and harbours. Convoys might never have been started but for the French government insisting that their cross-Channel colliers sailed in convoy. The result was dramatic but the Admiralty remained unconvinced. Perhaps the Admiralty officials thought that escorting dirty old merchant ships was not a fitting task for gallant young naval officers. Whatever their reasons, it took an ultimatum from the prime minister to make them change their minds. (Although later the admirals petulantly said they were about to do it anyway.) When convoys began in May 1917, only ships that could do better than 7 knots, and could not attain 12 knots, were allowed to join them. Losses fell about 90 per cent. The British had come close to losing the war, and before the effect of the convoy system became evident the nerve of the first sea lord, Admiral Jellicoe, broke. On 20 June he told a high-level conference that, owing to the U-boats, Great Britain would not be able to continue the war into 1918. He proved wrong and, thanks to the convoys, the crisis abated.
German U-boats continued sinking passenger ships even after negotiations for peace began on 3 October 1918. The following day Hiramo Maru was sunk off the Irish coast, killing 292 out of the 320 aboard. The following week the Irish mail boat Leinster was torpedoed without warning and torpedoed again while it was sinking: 527 drowned. ‘Brutes they were, and brutes they remain,’ said Britain’s foreign secretary. President Wilson warned that America wouldn’t consider an armistice so long as Germany continued its ‘illegal and inhuman practices’. The U-boat’s Parthian shots had not helped to create a climate suited to negotiations for a lasting peace.
By the time the First World War ended, about 200 U-boats had been sunk, but the submarine menace had been countered only by means of escorted convoys and the use of about 5,000 ships, hundreds of miles of steel nets and a million depth charges, mines, bombs and shells. Yet for those who wanted to find it, the most important lesson of the 1914–18 war in the Atlantic lay in the statistics. In the whole conflict only five ships were sunk by submarines when both surface escort and air patrol was provided, and this despite the fact that no airborne anti-submarine weapon had been developed.
The man who with undaunted toils
Sails unknown seas to unknown soils
With various wonders feasts his sight:
What stranger wonders does he write!
John Gay, ‘The Elephant and The Bookseller’
By the end of the First World War Britain was exhausted, financially bankrupt and in debt to the USA. The Empire, having made a selfless and spontaneous commitment to the war, no longer wanted to be ruled by men of Whitehall. British leaders, both civilian and military, had proved inept in conducting a war which, had the United States not entered it, Germany might well have won.
In 1922, Britain formally acknowledged her declining power. Since Nelson’s day Britain’s declared policy was to have a navy as strong as any two navies that could possibly be used against her. Even into the 1890s Britain was spending twice as much on her fleet as any other nation. With the Washington treaty of 1922 such days were gone. The politicians agreed that the navies of Britain, USA and Japan should be in the ratio of 5:5:3. Britain also accepted limitations upon the specifications of its battleships, and promised not to develop Hong Kong as a naval base and to withdraw altogether from Wei-hai-wei, China. In conforming to the treaty, the Royal Navy scrapped 657 ships including 26 battleships and battle-cruisers. One history of the British Empire comments: ‘So ended Britain’s absolute command of the seas, the mainstay and in some sense the raison d’être of her Empire.’1
After the First World War, the surrendered German fleet sailed to Scapa Flow, between Orkney and the Scottish mainland. There, in a gesture of defiance, they scuttled all their ships. This provided Germany with a chance to start again with hand-picked personnel and modern well-designed ships, while the victorious nations were patching up their old ships to save money.
The treaty of Versailles stipulated that Germany’s navy must be kept very small but in June 1935, acting without reference to friends or enemies, the British government signed an Anglo-German naval agreement permitting Hitler to build a substantial navy, up to 35 per cent as strong as the Royal Navy, and include battleships, virtually unlimited submarines and eventually cruisers and aircraft-carriers.2
This notable concession to Hitler’s belligerence encouraged him to ever more reckless moves and deeply offended Britain’s closest ally France. It went against all Britain’s international undertakings and, in grossly breaching the peace treaty, nullified it. The first lord of the Admiralty said: ‘the naval staff were satisfied and had been anxious to bring about an agreement’. Stabilization of Anglo-German naval competition would release RN ships to distant waters. Perhaps the British politicians – and the men in the Admiralty who advised them – believed that showing good will towards the Nazis would bring lasting peace. One suspects that it revealed some calculation in the minds of Britain’s leaders that a more powerful Fascist Germany would keep Communist Russia contained.
Significantly perhaps, the Reichsmarine was renamed Kriegs-marine and the Germans began building immediately. Germany’s four biggest battleships, Scharnhorst, Gneisenau, Bismarck and Tirpitz, which were later to give the Royal Navy so many sleepless nights, were laid down as an immediate result of this treaty. The following year Germany agreed – in the London Submarine Protocol of 3 September 1936 – that it would adhere strictly to the international prize law, which provided for the safety of merchant ship passengers and crews in time of war.
In 1937 came a supplement to the 1935 treaty. A German naval historian, Edward P. von der Porten, has described it as ‘a German attempt to convince the British of sincerity’. The Germans affirmed that they would build no battleships bigger than 35,000 tons. The Bismarck and Tirpitz, then in production, were 41,700 and 42,900 tons respectively. The extra tonnage, explained U-boat C-in-C Karl Dönitz after the war, was for ‘added defensive features’. In fact the extra size was due to Hitler specifying 15-inch guns instead of the previous 11-inch ones.
While German shipyards were producing these impressive warships Britain’s shipbuilding industry was antiquated and inefficient. It had suffered from the strikes and slumps that other British industry knew well. Yet while Britain’s merchant navy, although still large, was in decline, no such decline befell the bureaucrats of Whitehall. In 1914, with 62 capital ships in commission, the Admiralty employed 2,000 officials. By 1928 – with only 20 capital ships in commission, and the Royal Navy officers and men reduced from 146,000 to 100,000 – there were 3,569 Admiralty employees. Although the Washington naval treaty prevented any increase in Britain’s naval forces, there were by 1935 no less than 8,118 Admiralty staff on the payroll.3
Germany had ended the war without ships or shipbuilding facilities but the creation of a strong navy and a merchant fleet had been decided upon long before Hitler came to power. In the summer of 1929 these plans bore fruit as the ocean liner Bremen snatched the Atlantic Blue Riband from the elderly British liner Mauretania.
