The Army was formed in Salonika under Lieutenant-General Bryan Mahon to oppose Bulgarian advances in the region as part of the Macedonian front. The army arrived in Salonika (along with French troops) on 15 October 1915. In May 1916 Lieutenant-General George Milne replaced Bryan Mahon as commander of the Army.
