Using his friendly relations with the British, Kâmil Pasha also sat down to end the ongoing First Balkan War diplomatically. However, the heavy Ottoman military upsets during the war continued to sap morale, as rumors that the capital would have to be moved from Constantinople to inland Anatolia spread. The Bulgarian Army had soon advanced as far as Çatalca, a western district of modern Istanbul. At this point, Kâmil Pasha's government signed an armistice with Bulgaria in December 1912 and sat down to draw up a treaty for the end of the war at the London Peace Conference.
