Ship History
Built Electric Boat Company (Elco) in Bayonne, NJ. Laid down March 21, 1942. Launched July 3, 1942. Completed July 18, 1942. Delivered to the U. S. Navy (USN) as PT-112.

Wartime History
Assigned to Motor Torpedo Boat Squadron 5 (MTBRon 5) under the command of Commander Henry Farrow, USN. Assigned to the Panama Canal zone during September 1942.

On September 22, 1942 assigned to Motor Torpedo Boat Squadron Two (MTBRon 2) under the command of Lt Rollin E. Westholm, USN. During early October 1942, loaded aboard USS Tallulah (AO-50) as deck cargo along with PT-111 and shipped to the South Pacific.

On January 10, 1943 during the evening, PT-112 under the command of Lt. Westholm departed with PT-43, PT-40 on a mission to intercept eight Japanese destroyers expected off after midnight and patrolled off the north coast of Guadalcanal between Cape Esperence and Aruligo. Another group including PT-59, PT-46 and PT-36 patrolled between Tassafaronga to Doma.

Sinking History
On January 11, 1943 at 12:30am while patrolling off Guadalcanal a quarter mile offshore spotted four destroyers to the southeast a mile offshore, the last destroyer turned back towards Savo Island while the other three continued on their course. PT-112 motored in close to the target then fired all four torpedoes, one of which hit Hatsukaze, severely damaging the destroyer and putting a huge column of water into the air.

After the attack, PT-112 had to turn hard left to avoid a collision and passed astern of the Hatsukaze as other ships opened fire. Turning east under fire, PT-112 was hit twice at the waterline and near the forward bulkhead of the engine room. Damaged, Lt. Westholm ordered the crew to abandon ship and was the last to exit.

The crew deployed their life raft while PT-112 remained afloat. At 1:30am, Westholm attempted to return to the vessel and paddled to within 100' when the ship exploded and settled to the stern. By dawn, PT-112 sank into Iron Bottom Sound roughly one mile east of Cape Esperence on Guadalcanal.

Fates of the Crew
Afterwards, the crew was rescued by other PT Boats active that night and returned to duty.
