Hemingway was present during the Normandy landing on June 6th, 1944, but as a war correspondent, he was not permitted to leave the ship and had to conduct his correspondence from its deck.

He was also assigned to the 22nd Infantry Regiment and became commander of a small group of rural militia from Rambouillet near Paris. It is against the Geneva Conventions to lead a detachment and be a war correspondent simultaneously, but after interrogation by Inspector General, Hemingway was cleared of all charges. While in France, he managed to capture several Germans.
