14 November 1942:
ARIZONA MARU is officially classified and operated as an Army Air Defense Ship. That same day, at 0849, as Tanaka's Reinforcement Group proceeds down the "Slot" between the New Georgia and Santa Isabel Islands, the 23-ship convoy is
sighted by a reconnaissance Douglas "Dauntless" SBD dive-bomber from USS ENTERPRISE (CV-6). At 0908, the SDB attacks a transport, but is shot down by Japanese fighters.
Off Guadalcanal. At 1250, 18 Marine Corps SBD dive-bombers and seven USN Grumman "Avenger" TBF torpedo-bombers attack the convoy. Mitsubishi A6M "Zekes" shoot down some aircraft, but are engaged by Grumman F4F "Wildcat' fighters and cannot stop the attack.
CANBERRA and NAGARA MARUs are torpedoed and sunk. Destroyers AMAGIRI and MOCHIZUKI rescue 1,500 survivors. The Americans also damage cargo ship SADO MARU that is detached to Shortlands with AMAGIRI and MOCHIZUKI carrying among other survivors, MajGen Tanabe Suketomo, CO of the IJA’s 38th Division and other survivors.
At about 1430, SBD dive-bombers from ENTERPRISE and USMC SBDs of the "Cactus Air Force" at Henderson Field bomb and sink BRISBANE MARU. Destroyer KAWAKAZE rescues 550 survivors.
Beginning about 1500, two flights of Fifth Air Force B-17 “Flying Fortress” heavy bombers from the 11th Bomb Group (H) at Espiritu Santo, New Hebrides attack the convoy without success.
At about 1530, ARIZONA MARU and SHINANOGAWA MARUs are attacked by eight SBD dive-bombers from ENTERPRISE covered by 12 F4F fighters. Both transports are hit by 1,000-lb bombs and abandoned. Destroyer NAGANAMI rescues 570 survivors from SHINANOGAWA MARU and MAKINAMI rescues 1,020 survivors from ARIZONA MARU. 
In the last attack beginning about 1610, the planes sink transport NAKO MARU. Destroyer SUZUKAKE rescues 1,100 survivors. 
80 miles NW of Savo Island, Guadalcanal. A flight of four TBF torpedo-bombers of USMC VT-10 covered by six F4F fighters of USMC VMO-251 find ARIZONA and SHINANOGAWA MARUs dead in the water and nearby each other. The Marines also spot BRISBANE and NAKO MARUs further ahead. Two TBFs attack ARIZONA and SHINANOGAWA MARUs, but their unreliable Mark 13 torpedoes either miss or fail to explode. Another TBF drops a bomb and gets a direct hit amidships and sinks one of the transports. The other sinks shortly thereafter from previous damage. ARIZONA MARU sinks near 08-30S, 158-45E.
 Sources conflict as to ARIZONA MARU's secondary armament. Other Japanese sources say she carried 10 IJA Type 98 20-mm AA Machine Cannon.
 According to SORG, the attack was probably made by LtCdr William E. Ferrall's (USNA' 27) USS SEADRAGON (SS-194) at 16N, 120E. SEADRAGON fired one of BuOrd's unreliable Mark 14s.
 The Japanese lose about 450 men KIA in the 13 Nov '42 action, although troop losses and other casualties for individual ships are unknown. Altogether, the destroyers rescue more than 4,700 men.
Thanks go to Erich Muehlthaler of Germany, Gilbert Casse of France and the late John Whitman.
