King Constantine I of Greece abdicated June 12 under Allied pressure, as he was suspected of being overly-friendly towards the German Empire. His eldest son likewise was bypassed (he is a veteran of the German Army), leaving Alexander to ascend to the throne.

At Messines, the British Army’s advances were secured June 14, with no other fighting expected. Each side lost 25,000 soldiers, although nearly half the German losses are missing or captured.

Under pressure from conscientious objectors and other pacifists, the United States passed the Espionage Act on June 15, which makes it illegal to interfere with military operations or to discourage anyone from enlisting in the army.
