What happened June 1918 AD

Bormann's studies at an agricultural trade high school were interrupted when he joined the 55th Field Artillery Regiment as a gunner in June 1918, in the last days of World War I.

He enrolled at Yale University but left when the United States entered World War I to apply for flight training with the United States Navy. After completing training in June 1918, he was designated as a Naval Aviator and was commissioned as an Ensign in the United States Navy Reserve.

On June 28, the Treaty of Versailles was signed, which ordered Germany to reduce its military, take responsibility for the World War I, relinquish some of its territory and pay exorbitant reparations to the Allies. It also prevented Germany from joining the League of Nations at that time.
