…The sub was left running at about 10 knots with her rudder jammed hard right and in just about full surface trim. The Pillsbury's boat had to chase the sub and cut inside the circle to catch her, which she did, and the boarding party, consisting of eight enlisted men and Lieutenant (j.g. [junior grade]) Albert Leroy David, leaped from the boat to the circling sub and took possession of it. On deck there was one dead man. They didn't know what was down below. They had every reason to believe, from the way the sub was still running, that there were still Nazis left below engaged in scuttling, setting booby traps or perhaps getting rid of confidential gear. At any rate David and two enlisted men, one named Knispel, the other Wdowiak, plunged down the conning tower hatch carrying hand grenades and machine guns ready to fight it out with anyone they found below. They very definitely put their lives on the line when they went down the hatch. However, they found no one below. They did find that water was pouring into the U-boat through a bilge strainer about 8 inches in diameter which had the cover knocked off, and that all the vents were open and the boat was rapidly flooding. When they found there was no one else below they called the other boarders below and went to work closing vents. They found the cover to this bilge strainer, slapped it back in place, screwed up the butterfly nuts on it and checked the flooding, just in the nick of time. In the meantime another boarding party from the Guadalcanal arrived under the command of Commander Earl Trosino, Chief Engineer of the Guadalcanal, and took charge of the salvage operations. At this time the sub was so low in the water that to prevent the swells from washing down the conning tower hatch they had to close the hatch on the people who were working below. Those people down below wouldn't have had any chance whatsoever to escape in case the sub had gotten away from us….
