The German ships evaded the British fleet and passed through the Dardanelles to reach Constantinople, where they were eventually handed over to the Ottoman Empire.
Renamed Yavuz Sultan Selim and Midilli, the former Goeben and Breslau were ordered by their German commander to attack Russian positions, in doing so bringing the Ottoman Empire into the war on the side of the Central Powers.
Writing several years later, Winston Churchill—who had been First Lord of the Admiralty—expressed the opinion that by forcing Turkey into the war, Goeben had brought "more slaughter, more misery, and more ruin than has ever before been borne within the compass of a ship.
"[2] Dispatched in 1912, the Mittelmeerdivision of the Kaiserliche Marine (Imperial Navy), comprising only the Goeben and Breslau, was under the command of Konteradmiral Wilhelm Souchon.
Goeben was joined by Breslau at Taranto and the small squadron sailed for Messina where Souchon was able to obtain 2,000 short tons (1,800 t) of coal from German merchant ships.
At 09:30 on 4 August Souchon made contact with the two British battlecruisers, Indomitable and Indefatigable, which passed the German ships in the opposite direction.
However, a meeting of the British Cabinet decided that hostilities could not start before a declaration of war, and at 14:00 Churchill was obliged to cancel his attack order.
Provisioning his ships required ripping up the decks of German merchant steamers in harbour and manually shovelling their coal into his bunkers.
"[8] Milne was instructed on 5 August to continue watching the Adriatic for signs of the Austrian fleet and to prevent the German ships joining them.
He chose to keep his battlecruisers in the west, dispatching Dublin to join Troubridge's cruiser squadron in the Adriatic, which he believed would be able to intercept Goeben and Breslau.
When Goeben and Breslau emerged into the eastern Mediterranean on 6 August, they were met by Gloucester, which, being outgunned, began to shadow the German ships.
[9] Troubridge's squadron consisted of the armoured cruisers HMS Defence, Black Prince, Warrior, Duke of Edinburgh and eight destroyers armed with torpedoes.
By 04:00 on 7 August, Troubridge realised he would not be able to intercept the German ships before daylight and after some deliberation he signalled Milne with his intentions to break off the chase, mindful of Churchill's ambiguous order to avoid engaging a "superior force."
Breslau attempted to harass Gloucester into breaking off—Souchon had a collier waiting off the coast of Greece and needed to shake his pursuer before he could rendezvous.
On 16 August, having reached Constantinople, Goeben and Breslau were transferred to the Turkish Navy in a small ceremony, becoming respectively Yavuz Sultan Selim and Midilli, though they retained their German crews with Souchon still in command.
The mere presence of a powerful warship like Goeben in the Sea of Marmara would be enough to occupy a British naval squadron guarding the Dardanelles.
However, following German reverses at the First Battle of the Marne in September, and with Russian successes against Austria-Hungary, Germany began to regard the Ottoman Empire as a useful ally.
At the outbreak of the war, Churchill had caused outrage when he "requisitioned" two almost completed Turkish battleships in British shipyards, Sultan Osman I and Reshadieh, which had been financed by public subscription at a cost of £6,000,000.
The Turks had been neutral, though the navy had been pro-British (having purchased 40 warships from British shipyards) while the army was in favour of Germany, so the two incidents helped resolve the deadlock and the Ottoman Empire would join the Central Powers.
In the aftermath of Souchon's daring dash to Constantinople, on 15 August 1914 the Ottomans canceled their maritime agreement with Britain and the Royal Navy mission under Admiral Limpus left by 15 September.
Finally, on 29 October, the point of no return was reached when Admiral Souchon took Goeben, Breslau and a squadron of Turkish warships and launched the Black Sea Raid against the Russian ports of Novorossiysk, Feodosia, Odessa, and Sevastopol.
While the consequences of the Royal Navy's failure to intercept Goeben and Breslau had not been immediately apparent, the humiliation of the "defeat" resulted in Admirals de Lapeyrère, Milne and Troubridge being censured.
[16] Although a relatively minor 'action' and perhaps not widely known historical event, the escape of Goeben to Constantinople and its eventual annexation to Turkey ultimately precipitated some of the most dramatic naval chases of the 20th century.
General Ludendorff stated in his memoirs that he believed the entry of the Turks into the war allowed the outnumbered Central Powers to fight on for two years longer than they would have been able on their own, a view shared by historian Ian F.W.
