There was, fortunately, a way to reach the outer skin of the ship itself, through the forward trim tank. Located in the space between the pressure hull and the outer hull, the tank had been built to withstand full test pressure and to meet the highest specifications of shock resistance. It also was accessible through a manhole cover at the bottom of the torpedo storeroom.
Tom Thamm adjusted the trim of the ship so that all water normally carried in the forward trim tank could be pumped out of it and into the midships auxiliary tanks. (Balance fore and aft was maintained by pumping an equal weight of water to auxiliaries from the after trim tank.) Then the tank was opened and tested for gas. After it had been pronounced clear, Lieutenant “Whitey” Rubb and Machinist Phil Kinnie descended into the heretofore sealed space, carrying our jury-rigged transducer with them.
Placing the new mechanism carefully against the skin of the ship, alongside the internal keel, they quickly made a connection to a cable from the fathometer transmitter nearby. After all was in readiness, we began the first test.
For a moment, we were greatly encouraged. We actually heard a sharp click, as the outgoing signal sped through our handmade transducer. But there was no returning echo. Various combinations were tried, including partially reflooding the forward trim tank so as to submerge the transducer and thus increase its ability to transmit through the bottom of the trim tank and to the water outside. But in the end, we were completely disappointed. The effort was unsuccessful.
“Whitey” was dejected. “I’m satisfied this isn’t going to work, Captain,” he said. “But I’d like to keep trying.”
The only bright spot of the day was receipt of our fifth babygram. A boy, Donald, Jr., for Engineman First Class Donald R. Quick.

Without too much fact on which to base my supposition, I have always assumed that John Eichmann had been slated for transfer to his own command, possibly to be brought back to the States for a new construction submarine as was the custom for people who had spent a long time in the war zone [and later happened, in time, to me], and that he had either been pursuaded to remain for one additional patrol, or very likely had volunteered to do so in order to provide some kind of continuity for the new skipper.
