However, the military defeat of Greece against Turkey and the political unrest that it caused disrupted the life of Cecilie 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. The prince and his relatives hurriedly left Greece aboard HMS "Calypso" in early December 1922.
