Daladier had received military training before the war under France's conscription system. In August 1914, he was mobilised at the age of 30 with the French Army's 2nd Foreign Infantry Regiment when World War I started with the rank of sergeant. In mid-1915, the 2nd Foreign Infantry Regiment was destroyed in heavy fighting against the Imperial German Army on the Western Front. The surviving remnant of it was assigned to other units, Daladier being transferred into the 209th Infantry Regiment. In 1916, he fought with the 209th in the Battle of Verdun and was given a field commission as a lieutenant in the midst of the battle in April 1916 having received commendations for gallantry in action. In May 1917, he received the Legion of Honour for gallantry in action and ended the war as a captain leading a company. He had also been awarded the Croix de Guerre.
