My first assignment was on a light cruiser, Helena CL-50, at Pearl Harbor. . . . We were at 10-10 dock, which was the berth of the flagship of the Pacific Fleet, the USS Pennsylvania. The Pennsylvania had . . . moved from our buoy position to her position, to fix an anchor engine. When the Japanese attacked the next morning, their maps showed the Pennsylvania in our position; consequently, we caught the first torpedo. Alongside of us was a wooden minesweeper, the Oglala. The torpedo went under the Oglala, blew a hole in our after engine room, killing about sixteen, and tore the bottom out of the Oglala. She had to be towed in back of us, where she rolled over and sank. That was the extent of our damage during the attack.
