On January 8, 1944, Archerfish entered her assigned area, near Formosa. If any of her crew expected even this final lap of her 13,000-mile voyage to war to be a rest cure, they must have been disappointed, for every day of this two-week period was utilized for drill. Practice makes perfect.
To some extent a submarine is a weapon of opportunity. You cannot attack ships which do not arrive. If the seas are too rough, you have the devil’s own time keeping an efficient periscope watch, for if you run too close to the surface in order to increase your effective periscope height and see over the wave tops, you stand grave danger of “broaching”; that is, surfacing involuntarily as a result of wave action.
On her first patrol Archerfish and her disgusted crew fought heavy weather for two solid weeks, but finally she reported radar contact with four large and five smaller ships heading in the general direction of Formosa. The leading ship was attacked and sunk and Archerfish’s patrol report stated, “We had celebrated the first anniversary of our keel laying in right smart fashion.”
Months passed, and she was a veteran. The vast Pacific was her playground and her no man’s land. Then, as Joe Enright, her skipper, recorded in the fifth war patrol report of Archerfish, on November 28, 1944, she was patrolling submerged to the south and west of the western entrance to Sagami Nada, or outer Tokyo Bay. No ships had been sighted. No contacts of any kind (except fishing boats) had been made thus far in the patrol, which had begun twenty-nine days before.
At 1718 she surfaced, the visibility having decreased to such an extent that surface patrolling was feasible and desirable. With no premonition of the events which were to give him an enviable place in our naval history, the Commanding Officer ordered the regular routine of nighttime functions. A radar watch had of course been established the instant the ship broke water. Two engines were put on battery charge and one engine on propulsion at leisurely speed. Air compressors were started, and garbage was assembled, ready to be thrown over the side in burlap sacks. The crew settled down to the routine of alert watchfulness which is a concomitant part of night surface submarine operations in enemy waters.
At 2048 Fate finally uncovered her hand and brought together the characters she had been coaching for so long. Four years for Shinano and almost two years for Archerfish—time means little to the gods. How she must have sat back in her big, soft, easy chair, and chuckled. Having brought the two major characters of her play together, now she would leave it up to them, and see what would happen.
“Radar contact!” These words never fail to bring a shiver of anticipation to the submariner. From the size of the pip, the range, and the speed which the first few hasty moments of plotting show this target to be making, there is no doubt whatever in the minds of any of the crew of Archerfish that she is really on to something big. The word passes almost instantaneously throughout the ship, “Something big and fast!”
With the ease and sureness of long practice, tracking stations are manned. On the first word of radar contact, the Officer of the Deck had turned the bow of Archerfish directly toward the contact, and had stopped. This gave the plotting party an immediate indication of the direction of target movement. As soon as this had been determined, Archerfish roared off in hot pursuit, not directly at the target, but on such a course that she might have an opportunity of getting ahead of him. The main engine still on battery charge was replaced by the auxiliary engine, and all four great nine-cylinder Diesel engines were placed on propulsion. Within minutes after the initial contact, Archerfish was pounding along at full speed, 18 knots, throwing a cloud of spray and spume from her sharp knifelike bow as she hurried across the sea.
This is where the long, monotonous labor of patrol starts to bear fruit. Plotting and tracking the target is no simple matter. Every minute a range and bearing; every minute the singsong “Standby, standby, mark!” Every minute plotting parties plot the ship’s course and its position at the instant of the “mark”; then, from that point, they draw range and bearing, and thus locate the position of the enemy ship at the same instant. Your own ship twists and turns in the dual effort to gain firing position and to keep range to the target so that he will not sight her, or get radar contact on her, but keep close enough so that her radar will have no difficulty in keeping contact on his much larger bulk. After a few minutes of chase, the target’s course is determined to be roughly 210. The target’s speed is 20 knots; he is zigzagging, and by the size and strength of his radar pip is mighty big and mighty important. Radar also indicates four smaller vessels: one ahead, one on either beam, and one astern.
Joe Enright is climbing all over his ship like a monkey. First up to the bridge to be sure all is under control, then down to Plot to get an idea of what it is doing. Next, a quick look at the radar scope for a personal evaluation of what the operators have on there; then a quick look at the TDC; then back to the bridge. Then the whole thing over again.
The well-drilled crew are responding beautifully and solving the problem like clockwork, but all the information collected by his attack party must be transmitted to the Captain. It must be weighed in his mind; he must collect all the tiny details, any one of which might suddenly assume tremendous proportions. In no type of vessel is the Commanding Officer so personally responsible for the actual handling of his ship as in a submarine.
What is the state of moon and sea? It is better to attack with the moon silhouetting the targets instead of the submarine. But torpedoes run better if fired down the hollow of the waves rather than across them. The two considerations must be evaluated; the best decision reached. Not content with the mere reports of progress from junior officers and crewmen working below, the Captain has to be personally sure that they are not making mistakes. In his climbing up and down from control room to conning tower to bridge, it is necessary that he protect his night vision, as it would not do to have him partially blinded on the bridge when the crucial moment comes. Therefore, all below-deck control compartments are blacked out. No lights are allowed except the dim red glow of plotting party lights and the orange and green lights of the radar. All is silent in the control party, except the hushed reports which are continually going back and forth.
Archerfish is logging only 18 knots. This will not be sufficient. The call goes down from the bridge: “Maneuvering, make all the speed you can! All ahead flank!”
Watching their dials carefully, the electrician’s mates in the maneuvering room slowly increase the rheostat settings, and the thrashing propellers increase their speed another 20 r.p.m. The pitometer log registers now a little more than 18½ knots.
Again word from the bridge, “Control, give her a five-minute blow! Blow safety! Blow negative!” The scream and grind of the low-pressure air-blowing pump fill the interior of the ship. This low-pressure pump is used in the latter stages of surfacing when a large volume of air is required to complete emptying the ballast tanks of water. In this case, the intention is to blow out what residual amounts of water night remain or have leaked back in, in order to speed up the ship. Negative tank and safety tank are always kept full of water in order to carry out their designed purposes. Negative tank is so built that when it is full, the submarine properly compensated, and the ballast tanks flooded, the sub has negative buoyancy and will sink. Thus she dives faster. Safety tank, on the other hand, is used to give the ship quick, positive buoyancy, if she should need it. Altogether, these two tanks carry approximately thirty-six tons of sea water. Emptying them, while it decreases the safety factor with which the ship ordinarily operates, also decreases the amount of weight she had to drag around with her and hence increases her speed.
But in spite of these measures, Archerfish’s speed quivers around 19 knots or possibly a shade more. Still not enough. A third time from the bridge comes the order: “Maneuvering, give her all you’ve got! To hell with the volts and amps! Watch your motor temperatures, but give me more speed!” Shaking their heads—this is foreign to their training and upbringing—the electrician’s mates care
fully manipulate their rheostats once more. By means of the engine remote-control governor linkage, the r.p.m. of the four huge main diesel engines have already been increased to the maximum, and they are racing just as fast as they possibly can. Doubtfully the generators are loaded a bit more, and the amperes flowing to the four straining motors increase a trifle. The propellers increase their speed by another five or six r.p.m. Archerfish has done all she can, and the pitometer log dial now indicates 19½ knots.
At about this point, approximately one hour after the initial contact, the patrol report states, “Saw the target for the first time, an aircraft carrier! From here on it was a mad race to reach a firing position.”
It is every submarine skipper’s dream to find himself in hot pursuit of such a target. The jackpot—an aircraft carrier! The biggest game of all! Archerfish, the huntress. Can she bring this monster down in his own environment?
The skipper is all over the ship again, and visits the control stations at frequent intervals. He calls for Lieutenant Rom Cousins, the engineer officer, sends him back into the engineering spaces with instructions to squeeze out every possible extra turn on the laboring screws. He sends Dave Bunting to be sure that all last-minute adjustments are made on his torpedoes. There might even be time to pull and check all fish. When you stick your neck in the mouth of the dragon in hopes of getting a shot at him, you want that shot to be good.
The Communication Officer comes in for his share of attention. Joe Enright jots down a message on a piece of paper and hands it to him. Gordon Crosby disappears into the radio room, codes the message, and then stands watch on the radioman as he transmits: “NPM V W3TU—K . . . NPM V W3TU—K . . . Radio Pearl from Archerfish, I have an urgent message. . . . Radio Pearl from Archerfish, I have an urgent message.”
Straining their ears, the radiomen listen to the welter of dots and dashes filling the ether. Radio Pearl is busy; a lot of ships are calling it, and it is receiving a steady stream of messages. Archerfish must wait her turn. The answer from NPM says, Archerfish from Radio Pearl, Wait.
But this won’t do. “NPM V W3TU 000 K. . . . Radio Pearl from Archerfish, this message is really urgent!” There must be some means whereby a ship with an excessively important message can demand and receive immediate attention. Only in this way can any semblance of communication and traffic discipline be maintained.
Radio Pearl comes back immediately with a procedure sign to Archerfish. “Go ahead, we are ready.”
FROM ARCHERFISH TO COMSUBPAC AND ALL SUBMARINES IN EMPIRE AREAS AM PURSUING LARGE AIRCRAFT CARRIER FOUR DESTROYERS POSITION LAT 3230 N LONG 13745 E, BASE COURSE 240, SPEED 20.
NPM answers simply and very specifically, “R,” which means “Received, I assume responsibility, will forward this message to proper authority.”
By this time it is early morning at Pearl Harbor, but Admiral Lockwood has left orders with the duty officer to call him no matter where he may be, upon receipt of such a message. He hurries down to the office with his Operations Officer. It isn’t often that one of his submarines latches on to a prize of this kind. Together, with the large wall chart of the Japanese Empire before them, they lay plans to insure the destruction of Archerfish’s target. In less than an hour messages pour forth from Radio Pearl. The position, course, and speed of Shinano are given. All submarines which might be in a position to intercept her are ordered to proceed to various strategic points and there to lie in wait. Then a further message to Archerfish: KEEP AFTER HIM JOE YOUR PICTURE IS ON THE PIANO. The levity in this dispatch is not misplaced. Uncle Charlie knows his boys, and his boys know him.
On and on, on and on, straining every nerve, Archerfish pursues her quarry. The carrier is tracked at 20 knots. Archerfish can do no more than 19 or possibly a shade better. But the carrier is zigzagging. If Archerfish can detect his base course and parallel that, disregarding the zigs, she may be able to overtake him in spite of the disparity in speeds. But this is tricky, too, because on a zig toward Archerfish, the target group might approach close enough for one of the flank escorts to sight the laboring submarine. Conversely, a zig away might lead them out of radar range, where a course change would result in Archerfish’s pursuing in the wrong direction. So Archerfish cannot blindly charge ahead, but must conform to maneuvers of the target; she cannot lose him, nor can she let him get too close. With these considerations, resisting every move which might tend to increase the distance she must run, Archerfish doggedly sets about making an end around. Theoretically, it is possible to get around a target going faster than you are. It is possible, but mighty damn hard to do!
One hour before midnight the target group zigs toward, not enough to give Archerfish an opportunity to dive and attack on this leg, but sufficiently so that one of the flanking escorts approaches perilously near the submarine—6000 yards. Determined to take every conceivable, practicable chance to avoid being forced to submerge prematurely, the skipper orders all bridge personnel below, except for Lieutenant (j.g.) John Andrews, the Officer of the Deck. If Archerfish receives gunfire on the bridge, there will be only himself and Andrews up there to worry about.
But the escort ignores the submarine, and Joe Enright calls his lookouts back to the bridge.
At midnight the carrier force makes another big zig, to the west. Archerfish had expected that he was probably headed for somewhere in the Pacific, and therefore had chosen the left or southern flank of the convoy to trail from. A change of base course in the most probable direction, to the south, she hoped would drop the whole outfit into her hands. But such was not to be. The zig to the west puts the submarine even further out in right field, but doggedly she digs in and continues the chase.
For two and a half hours the pursuit goes on. Racing to crawl up the left flank of the task group, Archerfish finds that her top speed is just barely allowing her to pull ahead. But there is obviously no chance of attaining a firing position before dawn. Regretfully, the skipper composes another message.
URGENT—FOR COMSUBPAC AND SUBS IN AREA X TARGET COURSE 275 SPEED 20 X AM TRAILING LEFT FLANK X DO NOT EXPECT TO REACH FIRING POSITION BY DAWN X CONTINUING CHASE.
The answer is prompt, ARCHERFISH FROM COMSUBPAC X KEEP AFTER HIM JOE X ALL SUBMARINES IN THE FORCE ARE PULLING FOR YOU AND ARE BACKING YOU UP.
They are keeping a sleepless vigil at the operations office of ComSubPac, fortified by much coffee and Coca-Cola. But their encouraging message is never received by Archerfish.
For at 0300 the sands run out for Shinano. Base course is changed again, this time to nearly due south, and incredulously Archerfish finds herself almost dead ahead of the target. Fate picks up her dice and stows them away.
“Right full rudder!” The submarine changes course rapidly, heeling to port as she does so. At last Archerfish heads for the enemy.
Ah-oooh—gah! Ah—oooh-gah! The diving alarm seems more piercing than usual. “Dive! Dive!” “Flood negative! Flood safety!” “Battle stations submerged!” A few men dash through the ship to their battle stations, but most are already there.
“Hatch secured, sir!”
“Shut the induction!”
“Green board, sir!”
“Bleed air in the boat!” “Eight degrees down bubble!” “Easy on the bow planes!” “Blow negative!” “All ahead one third!” “Fifty-five feet!” Expertly each man does his job, and Archerfish smoothly slips beneath the waves. Radar gets a final range as the antenna goes under water: 11,700 yards, closing fast.
“Up periscope!” The long, shiny tube hums out of the periscope well. Squatting on his haunches before it, hands poised to catch the handles the moment they emerge, Enright resembles an ageless devotee of some obscure occult religion. Perspiration stands out unnoticed on his forehead, his face is immobile, his eyes staring. You would say he is in a trance, and in a trance he is, for his eyes do not see the crowded darkened conning tower around him. His eyes and mind already are on the surface of the ocean, watching the enemy task group as it comes closer—and closer.
. . .
Finally the periscope handles appear. Capturing and unfolding them with both hands, the skipper applies his right eye to the eyepiece and swiftly rises with the periscope to a standing position. He has become so accustomed to this procedure that he is entirely unconscious that he has performed quite a neat little stunt—for from the moment the periscope eyepiece appeared out of the periscope well he has been looking through it, has risen to a standing position with it, and has stopped rising smoothly as the eyepiece reached its upper limit. He slowly rotates the periscope from side to side, searching through the faint pre-dawn light.
“Down periscope! Target not yet in sight. What range do you have on the TDC?”
Since it still lacks more than an hour until dawn, the conning tower and control room are still darkened in order to make it possible to see through the periscope. The radar has been secured, and only the faint red glow of the TDC dial lights, the torpedo ready lights, and the sound gear dial lights are permitted. Dave Bunting consults the TDC range dial. “Range, eight oh double oh, Captain. Bearing two nine five.”
“Up periscope! Put me on two nine five!” The Captain snaps the command to his exec, “Bobo” Bobczynski, now functioning as Assistant Approach Officer. As the periscope comes up, the latter places his hands beside the Captain’s on the handles and swings the ’scope until the etched hairline stands at 295. The skipper looks long and hard, and infinitesimally rotates the periscope from one side to the other.
Throughout the ship the men are waiting for the answer to their unspoken questions: “Have we dived in the right place?” “Have we really outguessed him?” “Does the Captain see the target?”
Finally, in a low voice which hardly expresses conviction, and which certainly is far from showing the relief he feels, the Captain speaks. “I see him.”
The word flies through the ship. Men look at one another and smile, some a little shakily, but most, a tight-lipped grin of relief and pride. “We have him in the periscope!”
