Here’s the start of a page dedicated to Captain Allen Mullinnix.

The following information on Captain Mullinnix is quoted from The Indiana Magazine of History, “Hoosier Senior Naval Officers in WWII” by John B. Heffernan, 1955 (source):

“Rear Admiral Allen Prather Mullinnix was born in 1898, in Attica, attended New Albany High School and the Naval Academy, 1920, graduating 1919. He served on the staff of the commander of transports of the Atlantic Fleet and participated in the landings at Casablanca, Morocco, in November, 1942. He commanded the U.S.S. “Calvert” (APA-32), a troop transport, and then served in the Office of Naval Communications. In 1944 he assumed command of the U.S.S. “Pensacola” (CA-24). In this cruiser he participated in bombardments in the Kurile Islands, Wake Island, and in the assault and capture of Iwo Jima and Okinawa. He retired in 1947.”

Captain Mullinnix’s Navy Cross commendation (source):

“The President of the United States of America takes pleasure in presenting the Navy Cross to Captain Allen Prather Mullinnix, United States Navy, for extraordinary heroism and distinguished service in the line of his profession as Commanding Officer of the Heavy Cruiser U.S.S. PENSACOLA (CA-24), in action against enemy Japanese forces off Iwo Jima, Volcano Islands, on 17 February 1945. When a hostile heavy-caliber shore battery repeatedly hit his ship, causing extensive damage, fire and many casualties, Captain Mullinnix replied with vigorous, heavy and accurate counter-fire which silenced the enemy battery and, with cool courage, directed the rapid completion of emergency repairs, enabling the ship to remain on station and carry out its assigned mission. His aggressive fighting spirit and gallant devotion to duty were in keeping with the highest traditions of the United States Naval Service.” General Orders: Commander Amphibious Forces: Serial 0397 (May 1945)
