Ware arrived in France, under the 3rd Corps, in time for the last drive around
Chateau Thierry, one of the first actions of the A.E.F. under General John J. Pershing as a part of the Second Battle of the Marne. In mid-September 1918, Ware participated in the Battle of St. Mihel, as a member of the 80th Infantry Division in the First Army reserve. In October 1918, Ware became Chief Signal Officer of the 2nd Army, due to dismissal from the front lines as a result of being ill. Ware was in the push of the 2nd Army on November 9 during the Meuse-Argonne Offensive, during which he was wounded by a bursting shell, breaking his left ear drum; one piece hit his back below his left shoulder blade, left arm, and left hand. As a result of this he was recommended for the United States Signal Corps (U.S.C.) and became division signal officer under General Crondite and Jack Barnes, during which time he traveled to Langres to lecture to staff college. In November, Ware received notice that he would be sent with the new Army of Occupation, or 3rd Army, which was created following the armistice of November 11, 1918, in order to fulfill the duty of the Allies and the United States to control the administration of areas of the left bank of the Rhine. In the winter and spring of 1919, Ware traveled often, frequently in Toul, Mihiel, Coblenz, Luxembourg, and Nogent en Bassigny while based in Le Mans. In early July 1919, Ware received an order directing him to report to the Army of Occupation (The Third Army). On Bastille Day, Ware participated in the parade in Le Mans, however he disapproved of the event, stating that he wanted the money spent on the parade to go to aid for those in devastated areas. ==Germany==
