Around the World Submerged: The Voyage of the Triton

As I passed down through the conning tower into the control room, everyone sensed that this time my appearance heralded the time to dive. In the control room, Chief Radioman Joe Walsh, in charge of Triton’s radio gang, was Chief of the Watch. When he saw me, he put down the cup of coffee he was holding. Slight, with blond hair and aquiline features, Walsh had been one of the first to check out on our Ballast Control Panel. It must have been Walsh who had been operating the fathometer. No one was near it at the present time. Tom Thamm stood unobtrusively in the background. To Walsh’s left stood Bob Carter, Machinist Mate First Class, Auxiliaryman of the Watch. In build and size similar to Walsh, though darker and with jet black hair, Carter might have posed for illustrations of the lanky sailor so often characterized as the ideal man-o-war’s man. Career Navymen and submariners for years, Walsh and Carter both had thoroughly checked out Triton’s complicated equipment. We were in good hands.

Noting my attention, they self-consciously pretended unconcern. Inwardly, I smiled to myself. Diving was routine; Triton had already dived many times. But this was the start of our shakedown cruise, and they sensed that something out of the ordinary was planned. That this cruise was to be no ordinary cruise, this dive no ordinary dive, everyone on board must have realized.

I gripped the handrail of the ladder beneath the conning tower hatch through which I had just descended. Without even realizing they were doing it, Walsh and Carter ran their eyes over each of the individual controls before them, mentally checking them at the proper position and reviewing what they would do when the diving alarm sounded. For a moment or two nothing happened. Jim must be making a final check of the bridge, I thought. I hoped everything was tightly secured up there. Finally, I heard his voice through the bridge speaker system. “Clear the bridge. Clear the bridge!” Simultaneously, the diving alarm—an old-fashioned automobile horn—resounded through the ship.

Walsh’s hands flew to the controls for the hydraulic plants, started the stand-by pump, then waited, with his right hand hovering near the switch to the air inlet valve. It was a similar valve which somehow failed to close in 1939, when USS Squalus sank near the Isle of Shoals off Maine, losing nearly half her crew. In Squalus, this valve had been much larger than our own, for it supplied air to four great diesel engines in the engine room, whereas in our case it only provided ventilation below decks. But it was still important that it be closed when we dived.

The horn stopped; then came a second blast. I stepped clear of the hatch, and moments later a pair of legs clattered down the ladder, followed closely by another pair. Tom Schwartz, Torpedoman’s Mate Third—known variously as “the nose,” “the face,” or “the profile”—scrambled off the ladder and threw himself into one of the seats at the diving stand. William A. McKamey, Seaman, practically on Schwartz’s heels, settled himself at the other seat.

Jim Hay, as Officer of the Deck, would be the last man off the bridge. His next duty was to see that the watertight hatch leading to the bridge was properly shut. He would be up there right now checking it.

With the second blast of the alarm, Walsh snapped the switch to shut Triton’s main air valve. Then, playing upon the Ballast Control Panel as though it were an organ console, while intently eying the board of indicator lights glowing before him, he swept his hand swiftly and precisely across the face of the panel to open the twenty-two main ballast tank vents with which Triton was fitted. That done, he remained poised, one hand on the master switch which would shut at least half of the ballast tank vents, the other on the main air blow valve control. The bridge hatch still indicated open on his panel—as it should until completely closed. This is one of the crucial operations in diving; no skipper can completely divest himself of the urgent need to know that the bridge hatch has been properly shut. As soon as McKamey had passed me. I stepped back to the ladder and looked up into the conning tower. The ordered bustle there reassured me, as it always did, and as I looked up, Beacham’s voice sang out to Hay, “Hatch secured, sir!”

I cast my eyes quickly back to Walsh. He had relaxed ever so slightly. The red circle, indicating that the conning tower hatch was open, had been replaced by a single short bar.
