[2] In 1911, he won a competition for a specialized training with the Austro-Hungarian Army, enrolling in the seventh infantry division at Esseg for two years.

During vacation time, he was able to undertake trips to Berlin, Breslau, Venice, Paris, and Rome, attend maneuvers in Belgium and Switzerland, and spend a month in Egypt during the winter of 1910–1911.

His infantry regiment did not cross the Danube into Bulgarian territory, but instead guarded the capital Bucharest from Tunari fort.

There, he distinguished himself in battle on a hillside; gravely wounded in his left foot, Mihail was transferred to a field hospital in Nehoiu.

In May, the troops were dispatched to the turbulent province of Bessarabia, occupying a stretch along the Dniester river, in the Rezina-Rîbnița area.

In the summer of 1918, Mihail was called to Botoșani, where he was placed in command of a students' battalion from the local officers' school.

[3] From 1937 to 1939, he was chief of the Royal Household for King Carol II[4] and served as director of the National Military Circle.

[2] That day, General Ion Antonescu assumed full powers as Conducător, put Mihail on reserve status and placed him under house arrest in Sinaia.

[3] Mihail was reactivated on August 23, 1944, the day of Royal coup d'état, and again functioned as Chief of the General Staff from that point until October 12.

Manuscripts found in his home were particularly damning; these included, in the prosecutor's view, "a multitude of phrases containing insults and slanders addressed to the USSR and the Romanian regime".
