Killed in Blast

Lieutenant Arnold Marcus of Mill Valley and four of his shipmates on the submarine A-7, stationed at Cavite, Philippine Islands, were instantly killed yesterday in an explosion on board the undersea boat.

Marcus was a graduate of Annapolis, and his home was in Mill Valley, where his uncle, Gustav Marcus, of the California Jewelry company, and his widow now reside. He was 26 years of age.

The bereaved widow was Miss Helen Cowles, a niece of Mrs. Denis O'Sullivan and a granddaughter of Mrs. James Marion Curtis.

The dead reported in the official dispatches are Marcus, Harold Lang of Massachusetts; O. Hopewell, Missouri; Jesse M. Currie, Virginia; and Joseph A. Kunz, of Texas. Three men were badly burned and bruised.

Born in Atlantic City, New Jersey, Marcus was appointed a midshipman 22 May 1909. He assumed command of submarine A-7, 13 March 1917. On 27 July 1917, Lieutenant (jg.) Marcus died from injuries suffered during an explosion on A-7, while the submarine was on patrol in Manila Bay, Philippine Islands. He was the last man to leave the ship, remaining on board to ensure the safe evacuation of his crew and to attempt the grounding of his ship to prevent sinking.

USS Shark (Submarine # 8, later SS-8), 1903-1922.
Later renamed A-7

USS Shark, a 107-ton Plunger (later A-1) class submarine built at Elizabethport, New Jersey, was commissioned in September 1903. She served between then and early 1907 at the Naval Torpedo Station at Newport, Rhode Island, and subsequently at the U.S. Naval Academy at Annapolis, Maryland. In April 1908 Shark was loaded on board the collier Caesar for transportation to Manila, where she arrived in July. Renamed A-7 in November 1911, the submarine was employed for the rest of her active career as part of the defenses of the Philippine Islands. During World War I she conducted patrols in the entrance to Manila Bay. On 24 July 1917, while so engaged, she suffered an internal gasoline explosion and fire that took the lives of her Commanding Officer, Lieutenant (Junior Grade) Arnold Marcus, and several other crewmembers. USS A-7 was decommissioned in December 1919, though she had apparently been inactive since April 1918. Given the hull number SS-8 in July 1920, she had no further commissioned service. Later used as a target, she was striken from the Navy list in January 1922.
