He returned to the Army in 1928 as head of the Second Army Inspectorate. In 6–10 March 1933, he led the military government that was formed to confront an attempted coup by Plastiras. An outspoken Venizelist and Republican, he was again removed from the Army, along with many Republicans, in the aftermath of another failed Venizelist coup two years later. Subsequently, the monarchy was restored, and eventually a conservative dictatorship was established in Greece by General Ioannis Metaxas. During this period, and the Axis Occupation that followed, Othonaios remained in Greece, but engaged in no political activity. After Liberation in October 1944, he was placed as nominal commander-in-chief because of his democratic credentials, but the virulent political atmosphere, which soon led to the Greek Civil War, forced him to permanently resign in 1945.
