However, the military defeat of Greece against Turkey and the political unrest that it caused disrupted the life of Sophie and her family. In September 1922, Constantine I abdicated in favor of his eldest son, George II. A month later, Prince Andrew was arrested before being tried by a military tribunal, which declared him responsible for the defeat of the Sakarya. Saved from execution by the intervention of foreign chancelleries, the prince was condemned to banishment and cashiering. After a brief stop in Corfu, the prince and his relatives hurriedly left Greece aboard HMS "Calypso" in early December 1922.
