On 24 May 1915, after learning of the "Great Crime", the British, French and Russian governments issued a joint statement accusing the Ottoman government of "crimes against humanity", the first time in history that this term had been used. The British, French and Russians further promised that once the war was won they would put the Ottoman leaders responsible for the Armenian genocide on trial for crimes against humanity. However with the Anglo-Australian-New Zealand-Indian-French forces stalemated in Gallipoli and another Anglo-Indian expedition slowly advancing on Baghdad, the CUP's leaders were not threatened by the Allied threat to bring them to trial. On 22–23 November 1915, General Sir Charles Townshend was defeated in the Battle of Ctesiphon by Nureddin Pasha and Goltz Pasha, thus ending the British advance on Baghdad. On 3 December 1915, what was left of Townshend's force was besieged in Kut al-Amara (his forces surrendered to Halil Pasha five months later). In January 1916, Gallipoli ended in an Ottoman victory with the withdrawal of the Allied forces; this victory did much to boost the prestige of the CUP regime. After Gallipoli, Enver Pasha proudly announced in a speech that the empire had been saved while the mighty British empire had just been humiliated in an unprecedented defeat.
