Pursuit of Goeben and Breslau - Consequences

Consequences

In August, Germany—still expecting a swift victory—was content for the Ottoman Empire to remain neutral. 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. Tensions began to escalate when Ottoman Empire closed the Dardanelles to all shipping on 27 September, blocking Russia's exit from the Black Sea—the Black Sea route accounted for over 90% of Russia's import and export traffic.

Germany′s gift of the two modern warships had an enormous positive impact with the Turkish population. At the outbreak of the war, Churchill had caused outrage when he "requisitioned" two almost completed Turkish battleships in British shipyards, the Sultan Osman I and the Reshadieh, that had been financed by public subscription at a cost of £6,000,000. Turkey was offered compensation of £1,000 per day for so long as the war might last, provided she remained neutral. (These ships were commissioned into the Royal Navy as HMS Agincourt and HMS Erin respectively.) 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.
