Mission History
On December 23, 1943 took off from Munda Airfield piloted by 1st Lt. Theo Lee Sparks armed with four 500 pound bombs as one of twenty-three Avengers on a mission against Japanese bivouac and supply areas on southern Bougainville.

The formation of Avengers was divided into four divisions: attacking four separate target areas: 1) Mawareka, 2) Motupena Point, 3) Aitara Mission and 4) Mamagata Mission. The weather was 4/10 cumulus clouds with bases at 2,000' mostly over land with broken clouds 10,000' to 15,000' over the target area. Before reaching the targets, two Avengers aborted the mission.

En route to the target over Bougainville, the formation encountered Japanese anti-aircraft fire. While flying at roughly 1,500', this Avenger was hit in one wing, burst into flames then dove into the sea 100 yards off Aitara Mission. When this aircraft failed to return it was officially listed as Missing In Action (MIA). This Avenger was the first loss during the second tour of duty of VMTB-232.
