While the battle operations of the Fourth Brigade as an infantry brigade of the Second Division of Regulars overshadowed all others taken part in by Marine Corps personnel, those operations were by no means the only ones participated in by officers and men of the Marine Corps. The commanding general of the Second Division from early in August, 1918, to the date of demobilization, and several officers on his staff were Marine officers. Officers of the Marine Corps were at various times attached to the First, Second, Third, Fourth, Sixth, Twenty-sixth, Thirty-second, Thirty-fifth, Ninetieth, and Ninety-second Divisions, and in some cases engaged in operations with them. Brig. Gen. John A. Lejeune assumed command of the Sixty-fourth Infantry Brigade of the Thirty-second Division, then in the front line on the Swiss border in the Suarce sector, on July 5, 1918. He was in command of this brigade on July 22, 1918, when it was withdrawn from the above-mentioned sector and continued in command until July 25, 1918, when he left to command the Fourth Brigade of Marines. Between July 5, 1918, and July 22, 1918, Brig. Gen. Lejeune, in addition to the Sixty-fourth Brigade, commanded three French infantry regiments. Col. Robert H. Dunlap was in command of the Seventeenth Field Artillery Regiment of the Second Field Artillery Brigade, Second Division, from October 30, 1918, to February, 1919. Col. Hiram I. Bearss commanded the One hundred and second Regiment of the Fifty-first Infantry Brigade, Twenty-sixth Division, in the St. Mihiel offensive. Col. Frederic M. Wise commanded the Fifty-ninth Regiment of the Eighth Infantry Brigade, Fourth Division, from September 5, 1918, to January 4, 1919, during which period he participated in the St. Mihiel and Meuse-Argonne major operations. From January 1, 1919, to February 9, 1919, Col. Wise commanded the Eighth Infantry Brigade of the Fourth Division. A few Marine officers and enlisted men engaged in Army aviation operations and suffered casualties. About 20 Marine officers were sent to France as observers and as such participated in operations with American, French, and British forces. Marine aviation personnel served in France as the Day Wing of the Northern Bombing Group of the Navy. Marine flyers served with Squadrons 213 (pursuit squadron), 217, and 218 (bombing squadrons), Royal Flying Corps of England; and with pursuit, observation, and bombing squadrons of the French Flying Corps. Quite a few casualties were suffered by the Marine aviation personnel. The First Marine Aeronautic Company, naval base No. 13, Ponta Delgada, Azores, equipped for water flying only, performed patrol duty from January, 1918, until November 11, 1918. The Marine Aviation Section, naval air station, Miami, Fla., performed arduous patrol duties in the Florida Straits in connection with the Navy from July, 1918, until the date the armistice went into effect.
