Moored next to Helena at 1010 Dock, Oglala was severely
damaged when a torpedo passed beneath her and detonated against Helena. The concussion
from this explosion ruptured her port hull, causing extensive flooding. Moved astern
of Helena, Oglala capsized to port. Two attempts to raise her failed, but the third
attempt on July 3, 1942 was successful. Repaired in drydock, she sailed for the West
Coast in December and was converted into an engine repair ship. She was recommissioned
ARG-1 on February 28, 1944.
