Andrew was given command of the II Army Corps during the Battle of the Sakarya, which effectively stalemated the Greco-Turkish War (1919–1922). Andrew had little respect for his superior officers, whom he considered incompetent. He was ordered to attack the Turkish positions, which he considered a desperate move little short "of ill-concealed panic". Refusing to put his men in undue danger (suffering lack of food and ammunition), Andrew followed his own battle plan, much to the dismay of the commanding general, Anastasios Papoulas. Relieved of his chief of staff, and given a dressing-down by Papoulas, in September Andrew asked to be removed from command but Papoulas refused. Andrew's troops were forced to retreat. He was placed on leave for two months, until he was transferred to the Supreme Army Council. In March 1922, he was appointed as commander of the V Army Corps in Epirus and the Ionian Islands. Papoulas was replaced by General Georgios Hatzianestis.
