The Salonika campaign – chosen out of several strategic options presented by Sarrail – was intended originally to support Serbia, with Bulgaria entering the war on the side of the Central Powers, and later (as the Gallipoli campaign was winding down) to provide a chance for France to assert her economic and political influence over Greece and the declining Ottoman Empire. Sarrail ended up commanding a multinational Allied force amidst political intrigue and a state of near civil war in Greece, whose King Constantine was pro-German, whilst the Prime Minister Venizelos was pro-Allied and also keen to gain territory off the Turks in western Anatolia. Despite a number of offensives, Sarrail's forces did not succeed either in conquering Bulgaria or in preventing the Central Powers' conquest of Serbia in 1915 or Romania in 1916.
