Philip Haag spent nearly all of World War I aboard the USS Wyoming as a member of the United States Marines. The exact date of his enlistment is unknown, but by August 1917 he was on board the battleship transporting soldiers between Norfolk, Virginia and New York. Philip and his shipmates crossed the Atlantic in February 1918 and remained near Scotland for several months. Once armistice was reached and censorship regulations abolished, Philip was able to inform his family of the Wyoming's wartime maneuvers. The Wyoming aided in the search for the German fleet in the North Sea as part of the Sixth Battle Squadron. It returned to New York in January 1919, bearing Philip and many homecoming soldiers. He was transferred to a casual company in Philadelphia, Pennsylvania, and received his discharge in April of that year. Philip's brother, Harold Haag, also served in the military during World War I, but only limited information is available. Having trained at Camp Grant, Harold was assigned as a draftsman in the 35th Engineers of Company C and sent to France. A portion of one of his thumbs had to be removed due to an injury, the cause of which is unknown. Harold was transferred to the 19th Regiment of Company P and remained with this group through the end of the war.
