surface ships". Hayes was transferred back to the mainland in late November 1941, due to a scheduled rotation, and stationed at Fort Bragg. From December 1941 to March 1942 Hayes briefly served as the professor of Military Science and Tactics at Harvard University. After leaving Harvard, Hayes served as the chief of staff of Army's First Service Command. On June 22, 1943 Hayes was promoted to brigadier general. He served as deputy chief of staff of all Army Service Commands and, effective December 1, 1943, was appointed the head of the Third Service Command, covering Maryland, Pennsylvania and Virginia. In January 1944 Philip Hayes was promoted to the two-star rank of major general, with the U.S. Senate confirming his promotion on January 27, 1944. As head of the Third Service Command, Hayes oversaw much of the logistics related to the war production in the Maryland-Pennsylvania-Virginia area; this included having to deal with a thorny issue of employment of prisoner of war, where the U.S. laws and the restrictions of the Geneva Convention were difficult to reconcile.

General Hayes was put in charge of the military seizure of the Philadelphia Transit Company. He acted decisively and brought the strike to an end within a few days. After brief negotiations, Hayes issued an ultimatum on August 5 that those strikers who would not return to work by August 7, would be fired and refused the War Manpower Commission job availability certificates for the duration of the war, and that those between ages of 18 and 37 would also lose their military draft deferments. The strike was over by August 7 and the situation quickly returned to normal; the city of Philadelphia avoided a major outbreak of racial violence that had been feared by many at the start of the strike. For his role in quickly bringing the Philadelphia strike to an end, Gen. Hayes was later awarded a Legion of Merit. Hayes was awarded the
