"One-four-oh-double-oh!" The scope dropped away.
"Angle on the how still the same. Starboard ten." Keith was spinning his TDC cranks with both hands.
"Any other ships in sight, Captain?" This was Jim. "No," I said, "no escorts."
"I have the dive, Captain, depth sixty feet." Tom had climbed up two or three rungs of the ladder to the control room, had his head at the deck level.
"Very well." I turned to Keith. "What's the course to close the track with about a thirty-degree angle?" Keith looked at his dials for a moment. "We're on it now, sir. Recommend no change. What kind of a ship is it, Captain?"
Jim had finished orienting the Is-Was, now crowded between Hugh Adams at the plotting table and Keith at the TDC. He looked at me with that same look of anticipated pleasure, that eagerness for combat that I had recently noticed.
"Can't tell yet. Buff superstructure, black stack, two masts. Some kind of a cargo vessel."
"Is he smoking?"
"No-no smoke at all."
"New ship then, Anyway, in good shape."
I nodded.
Up forward of the periscope hoist motors was the under- water sound receiver and control equipment for the sound heads under our bow. I leaned over alongside the earphoned sonar operator. His pointer was going around steadily and slowly. He shook his head at my inquiring glance'. I indicated the area on our starboard bow as the place for him to concentrate on, stepped back to the periscope, motioned with my thumbs.
"Zig to his right," I called. The angle on the bow, had changed, was now port twenty degrees, and I could see more of the enemy ship, a large new-type freighter. As I turned the periscope something, else caught my eye-a discontinuity in the horizon-another mast. It would indeed have been highly improbable that a large, valuable freighter should be coming out of port unescorted. I looked closely on the other side, then back again. There were two small masts, one on either side, both apparently abeam or a little distance astern. This would not be as easy an approach as I had for a short time been hoping. "He has two escorts, Jim,' I said.
"What kind?"
"Can't tell yet. They're a lot smaller and I can't see them.
Quin was watching me. He picked up the telephone mouthpiece, spoke into it briefly. I could visualize everyone in the ship getting the word: 'The skipper sees two destroyers up there!"
"Jim," I said, "have the ship rigged for depth charge.
Shortly before we fire we will go to silent running also."
"Right," said Jim, as he squeezed by me to relay the necessary instructions to Quin.
Several observations later the situation had developed more clearly. Our target was a single large merchantman with cargo hatches forward and aft and four large goal-post type derricks. She had a single low, fat stack rising out of an amid- ships deckhouse evidently fitted for passenger accommodations.
The ship had obviously come out of Bungo Suido and was headed south, perhaps bound for Guam or Saipan, making respectable speed and escorted by three old type destroyers.
One escort rode on either beam of the target and the third one, which I had not seen until some time later, was following astern.
I could feel Walrus tense up as the target drew steadily near her. He was zigzagging, presenting first one side and then the other. We were right on his base course and had only to maneuver for a shot as he went by. I could feel myself tense up as well as the crucial moment approached.
We closed off the ventilation system, the air-conditioning machinery, and all other equipment not absolutely essential to the progress of the business at hand. The sweat spurted out of my pores, ran saltily down my cheeks and into the comers of my mouth. I ran my hands ceaselessly through my moist hair, wiped them off on my trousers. Hugh Adams was bothered by sweat dropping off the end of his nose onto his carefully laid-out plot.
Through the periscope I could see the whole ship now, even her red waterline heaving in and out of the sea. I had directed Tom to run several feet deeper to reduce the amount of periscope exposed, leaving me just enough height to make observations between passing waves. The range had closed to about two miles when the target made another zig.
"Angle on the bow-starboard thirty-five," I sang out, as the periscope descended. "Keith, what's the distance to the track?"
"Two thousand yards, Captain."
"Torpedo run?"
"Two-seven-double-oh." Jim, detailed to the angle solver on firing, relayed this one for me.
"Are we ready to shoot, Jim?" Jim glanced upward at his check-off list. My eyes followed his. Every item on it but one — had been neatly checked off in grease pencil. "We're ready to shoot, Captain, except that outer doors are still closed."
According to the Pearl Harbor submarine base our torpedoes were prone to flood if left exposed in the torpedo tubes with the outer doors open for too long a period. It was advisable not to open them until just before firing.
I turned to Quin. "Open the outer doors forward."
"Open the outer doors forward," he echoed into his tele- phone transmitter. Up forward at the command the torpedo- men would speedily crank- open the heavy bronze torpedo tube muzzle doors. This was the last act in the preparation of torpedoes for firing.
I nodded for the periscope, crouched before it till it came up, rode it to its full extension, spun it around, lowered it.
"We're inside the screen," I said. "The near escort will pass astern, well clear." I failed to mention that the rear escort, a few hundred yards astern of the target, would lay no means pass clear. Within minutes after firing, he would be upon, us. No point in alerting or worrying our crew at this stage over something that could not be helped.
"We'll give him three torpedoes on a ninety track, or as near to it as we can!"
"Ninety track. Three fish spread!" echoed Jim.
"The next observation will be a shooting observation! Stand by forward!" My mind racing, I studied the slowly moving dials on the face of the TDC. We could already shoot at any time. It was only a matter of waiting until the situation was most favorable. The "correct solution light," a red F, was glow- ing brightly on the face of the angle-solver sector of the TDC.
The "torpedo run" was well within maximum range of the torpedo. It would only be a few seconds longer.
I could feel the taut expectancy of the ship, this was to be our first kill. In the forward part of the conning tower O'Brien, the sonarman, had put the propeller beats on the laud-speaker.
We could hear the "chug-a-chug, chug-a-chug, chug-a-chug, chug-a-chug," as the enemies screws came closer and closer.
Less distinct was the lighter, high-pitched beat of the nearest escort. "Thum, thum, thum, thum." The sonarman switched from one to the other, kept them both coming in. It looked about time.
"This is a shooting observation," I said again. "Up periscope!" The periscope handles met my outstretched hands.
I snapped them down, put my eye to the eye guard. "No change," I said. "Bearing-Mark!"
"Three-three-six."
"Range", — I turned the range knob-"Mark!"
"One-eight-five-oh."
"Shoot," I said, snapping the handles up as the signal for the periscope to start down. Quin had turned around facing the firing panel, had turned the switch of Number One torpedo tube to "On."
"Fire!" shouted Jim. Quin leaned on the firing key. Walrus shuddered. Over the sonar loud-speaker I could hear the torpedo whine out of the tube. Jim made an adjustment to the face of the angle solver with his right hand, held a stop watch in his left, watched it intently. "Fire Two!" he shouted.
Quin leaned on the firing key a second time.
Another adjustment by Jim, then "Fire Three!" and Walrus jerked for the third time. I motioned for the periscope again, took a quick look. Our torpedoes were running nicely.
