In October 1922, Prince Andreas was arrested in Corfu. He was held responsible for the catastrophe in Asia Minor and was put on trial, which took place after the so-called “Trial of the Six”.

Vasilopais participated in the campaign from June 1921 as a member of the Royal Staff and returned to Greece before its dramatic conclusion.

His attitude to the battle of Sangario, in which he took part as commander of the 2nd Army Corps, that is, whether he showed indiscipline at the command of Commander-in-Chief Papoulas, occupied him in 1922 and is still being discussed. .

The issue of Cathimerini, published on November 20, 1922, was devoted almost entirely to his trial.

According to the report, the clerk of the court-martial read out the order to bring the prince to trial, noting: “Then our Army, in its advance on Sangarion, stopped at Calais Grotta for supplies, the Army, having information that the enemy was approaching, to take the initiative of action, and for he does not move his forces, ordered the 3rd Army Corps to defend to the end, and the other two to attack if the enemy attacks. […] Regardless of the correctness of the order, it was clear and categorical. […] Vasilopais Andreas refused to carry out the order of the Army, so he is put on trial.”

Revolutionary Commissar Kalogeras was just as clear: “I blame Vasilopaid Andrean for refusing to move against the enemy on August 26, 1921, despite the orders of the army.” Among his witnesses for the prosecution was An. Papulas, the commander of the Asia Minor army, who participated in the decisive operations at Sangario.

In an apology, the prince denied the indictment, citing “various arguments proving that the departure from Sangario was not connected with the actions of the 2nd Army Corps” and concluded: “Not a single order of the army remained unfulfilled.

The orders were to attack Vaughan’s army corps when notified, not Wu. Did this notification come to me? No”.

Eventually Prince Andreas was sentenced to life imprisonment and demoted from the military rank.
