- USS Trigger (SS-237)
USS "Trigger" (SS-237) was a "Gato"-class
submarine , the first ship of theUnited States Navy to be named for thetriggerfish , any of numerous deep-bodied fishes of warm seas having an anterior dorsal fin with two or three stout erectile spines."Trigger"'s keel was laid down on
1 February 1941 atMare Island, California , by theMare Island Navy Yard . She was launched on22 October 1941 sponsored by Mrs. Walter N. Vernou and commissioned on30 January 1942 with Lieutenant CommanderJack H. Lewis (Class of 1927) in command.__TOC__The submarine sailed for
Hawaii on22 May and reachedPearl Harbor the following week. She sortied forMidway Island with Task Group 7.2 (TG 7.2) on29 May in anticipation of a Japanese attack on that island. Her station during the ensuingBattle of Midway was northeast ofMidway Island , and she remained there without contacting any enemy shipping until she was ordered back to Pearl Harbor on9 June .First patrol: June–August 1942
On
26 June , "Trigger" got underway for theAleutian Islands to patrol an area west ofCape Wrangell ,Attu Island . She encountered six destroyers, three freighters and a patrol boat, attacking none, before calling atDutch Harbor on8 August "en route" back toHawaii .Second patrol: September–November 1942
"Trigger"'s second war patrol, conducted from
23 September to8 November with CommanderRoy S. Benson (Class of 1929) in command, took her to Japanese Home Waters. In the early morning hours of5 October , the submarine sighted smoke on the horizon and headed for it. A vessel soon appeared, coming toward the submarine. As the target approached, the submarine identified it as a small ship. "Trigger" then surfaced and manned her machine guns. However, when the submarine neared the target, she learned that the Japanese ship was larger than she had at first appeared to be. Enemy shells soon began exploding close to "Trigger", and the 4000-ton ship turned and came on fast in an attempt to ram. The submarine barely avoided a collision as she submerged for an attack. "Trigger" fired two torpedoes and heard one hit. She then surfaced and gave chase, only to have the target again open fire. The submarine missed with three more torpedoes and then discontinued the pursuit.Before dawn on the morning of
17 October , "Trigger" made a surface attack on a freighter off theBungo Suido . She fired two spreads of torpedoes which sank "Holland Maru" with her guns still firing. That night, adestroyer came out of Bungo Suido and dropped a string ofdepth charge s near the submarine. "Trigger" fired three torpedoes "down the throat" at the onrushing destroyer and, one minute later, observed an explosion so powerful it threw enough flame and water into the air to obscure the target. When the air cleared, the enemy ship was still intact, suggesting "Trigger"'s first torpedo may have exploded prematurely, detonating the next two by its turbulence. The submarine fired one more torpedo as the enemy disappeared, but failed to score a hit.Near midnight of
20 October , "Trigger" fired a spread of four torpedoes from very close range, 900 yards (820 m), in a surface attack on a 10,000-ton tanker. Two torpedoes hit the enemy ship as it turned in an attempt to ram. The submarine went to 100 feet (30 m) to evade a counterattack and heard a heavy explosion as either gasoline, magazines, or boilers blew up. She then came up to periscope level but found nothing in sight. (This sinking was not confirmed byJANAC postwar.) Four days later, "Trigger" attacked a large enemy tanker in ballast. A spread of three torpedoes produced three observed hits, one near the target's stern. The screws of the enemy ship stopped, and she began emitting heavy white smoke aft. She soon got underway again. "Trigger" fired her last torpedo at the ship as it was moving off and missed. That night, she surfaced and began her homeward voyage.Third patrol: December 1942–January 1943
From
3 December 1942 to22 January 1943 , the submarine conducted a combined minelaying and offensive patrol in waters surrounding the Japanese home islands. On20 December , she began planting a minefield offInubo Saki ,Honshū . "Trigger" planted the northern half of the field and was working on the southern part when a cargo ship passed her, heading into the newly-laid mines. Five minutes later, a violent explosion rocked the freighter which sank as an escort circled her. The submarine later heard another explosion from the direction of the minefield and, when she surfaced the next day, found the field was covered by smoke.On
22 December , "Trigger" sighted a ship approaching fromUraga and made a surface attack. A spread of three torpedoes produced one hit forward of the bridge, and the target started to settle by the bow. The submarine fired one more torpedo into the ship and, when last seen, "Teifuku Maru" was awash forward with her screws nearly out of the water. On31 December 1942 , she attacked a cargo ship loaded with planes. "Trigger" fired three torpedoes from extremely close range, 700 yards (640 m), and watched two hit. The target began to list to starboard and was down by the bow. Sound reported a heavy secondary explosion. The submarine came up to periscope level and saw the freighter with her stern high out of the water and adestroyer approaching. She went deep and when she next came up for a look, there was nothing to be seen. (The sinking was not confirmed by JANAC postwar.)On
10 January 1943 , a Japanesedestroyer approached "Trigger", and the submarine fired three torpedoes from 1600 yards (1460 m). One hit under the well deck and folded the destroyer's forecastle up at a 45-degree angle, and another hit the target's stern. Soon, the "Minekaze"-class destroyer "Okikaze" sank on an even keel.Fourth patrol: February–April 1943
"Trigger" stood out of
Midway Island on13 February to patrol off thePalau Islands . Two weeks later, she fired four torpedoes at a freighter, but the target managed to steer between them. Heavy air cover prevented a second attack. On4 March , the submarine attacked a freighter in a rain squall, but all three of her torpedoes missed. On15 March , "Trigger" sighted a convoy steaming in two columns. There were two freighters in the right hand column and three in the left with an escort on the outboard bow of each. She worked her way between the two columns and fired three torpedoes at each of the leading ships. She hit the lead freighter in the left hand column twice but missed her target on the right because it unexpectedly changed course. "Trigger" then fired three more torpedoes at the right lead ship at just 700 yards (640 m) and observed two hits before the escorts forced her to go deep. When she surfaced again, there was nothing to be seen. "Trigger" was later officially credited with having sunk "Momoha Maru", a 3103-ton cargo ship.That night, the submarine fired six torpedoes at a ship that was being towed by a smaller freighter. Five of the torpedoes missed, and the sixth made a circular run and passed over the submarine's engine room. A shaken crew broke off the attack.
On
20 March , the submarine fired three torpedoes at the lead ship in a convoy of four cargomen. One hit caused the target to list ten degrees to port and stop, but it soon got underway and rejoined the convoy. "Trigger" terminated the patrol at the Submarine Base,Pearl Harbor , on6 April .Fifth patrol: April–June 1943
Between
30 April and22 June , the submarine made a patrol which returned her to Japanese home waters. Directed byUltra from Pearl Harbor, "Trigger" lay athwart the projected track ofAdmiral Koga returning fromTruk . Koga'stask force came in sight the morning of22 May , but zigged away, out of range, "a bitter disappointment". [Blair, "Silent Victory", p.428] On28 May , "Trigger" contacted two freighters offIro Saki and launched three torpedoes at the larger. One hit its target aft. When last seen, the ship was down by the stern. The next day, the submarine fired a spread of three torpedoes at a small cargo ship. Two missed and the third exploded prematurely. She then launched a fourth which apparently hit but failed to explode.On
1 June , the submarine was searching for Japanese shipping offSagami Nada when she sighted two columns of smoke. She closed the range toward a firing position, made out two cargo ships, and fired a spread of three torpedoes at each target. Hit in her stern, the lead ship, "Noborikawa Maru", sank immediately. The second ship saw the torpedo wakes, turned and passed between them. "Trigger" then fired a torpedo at the oncoming ship; but, if the torpedo reached the target, it failed to explode.Again alerted by Ultra, on
10 June (her last day on station), "Trigger" sighted anaircraft carrier protected by twodestroyer s. She closed and sent six torpedoes streaking onward against Koga's flagship from only 1200 yards (1100 m). The submarine heard four explosions as she went deep to avoid the escorts which kept her down for several hours. Yet two missed ahead, and one failed to explode. [Blair, "Silent Victory", p.430] The damaged "Hiyō" limped intoTokyo Bay and was out of action for almost a year. Lockwood, who knew "Hiyō"'s fate, was furious. Had the torpedoes functioned correctly, Benson would have claimed her. The next day, "Trigger" began her return voyage toPearl Harbor ; just after her triumphant return, theMark XIV torpedo 's defectivemagnetic exploder was ordered deactivated.Sixth patrol: September 1943
On
1 September , after a yard overhaul, "Trigger" (now in the charge of CommanderRobert Edson "Dusty" Dornin {Class of 1935}) was ready to begin her sixth war patrol. It took her into theEast China Sea , off theChina coast, north of Formosa. On17 September , she made two hits on a Japanese freighter, one aft and one on the bow, but both torpedoes proved to be duds. The next day, she again contacted the same ship and fired four torpedoes at her. One struck "Yowa Maru", and the 6435-ton cargo ship slid beneath the waves.21 September was "Trigger"'s best day. She was patrolling some convert|30|mi|km north of theHoka Sho light when she sighted a convoy of three tankers and three freighters protected by Japanese planes. The submarine attacked the tankers first, firing three torpedoes at the leader and three at the second. One hit aft was seen on the lead tanker, and flames shot over 500 feet (152 m) into the air. Her crew, dressed in whites, could be seen running forward to escape the fire. One torpedo hit the second tanker amidships, and it broke in half beneath the stack and sank immediately. "Trigger" turned and fired three stern tubes at the third tanker. This target swung toward the submarine, and all three torpedoes missed. "Trigger" then fired another torpedo which hit the ship's starboard side. When the submarine went deep, her commanding officer slipped and fell into the periscope well as the quartermaster was lowering it. He supported himself on his elbows, and the quartermaster heard his shouts in time to prevent a serious accident. Sonar reported two more explosions before the submarine came up to periscope depth to resume the attack. "Trigger" fired two bow torpedoes at the third freighter in the column and scored two hits on the target which went down by the bow. The submarine then made two more attacks on the freighter, but all of her torpedoes either missed or were duds. During the three and one-half hours of action, "Trigger" sank two tankers, "Shiriya" and "Shoyo Maru", and a freighter, "Argun Maru", for a total of 20,660 tons of enemy shipping. The submarine returned toMidway Island on30 September to be refitted and rearmed.Seventh patrol: October–December 1943
The
East China Sea andYellow Sea were "Trigger"'s objective for her seventh patrol. She stood out ofMidway Island on22 October and proceeded to her patrol area. At 22:00 on1 November , she sighted a convoy that was steaming in two columns. When a ship in the nearer column overlapped one in the more distant group, she fired a spread of three torpedoes at them. One torpedo struck the nearer freighter in her bow and one hit the farther ship amidships. The submarine saw the nearer ship go down by the bow, before she herself was forced to go deep where she was severely depth-charged by two escorts.In the early morning of
2 November , "Trigger" fired three torpedoes at a freighter and scored one hit. At 00:50, she attacked the ship again with a spread of another three. Two of them hit forward, and "Yawata Maru" went down, bow first, in a vertical plunge. Two hours and 25 minutes later, "Trigger" fired three torpedoes at a 7148-ton transport. All torpedoes hit the ship, and "Delagoa Maru" disintegrated. On5 November , the submarine attacked a convoy of three cargo ships protected by onedestroyer and two planes. "Trigger" fired three bow tubes at the second ship in the convoy and one bow tube at the third before she went deep to avoid the escort which dropped 20depth charge s. Thinking she was clear, the submarine came to periscope depth and was greeted by five near bomb misses.On
13 November , "Trigger" made a submerged approach on a convoy of nine merchantmen and four escorts. After the Japanese ships zigged, the submarine found herself between two columns of ships—with empty bow tubes. She emptied her stern tubes at the last and biggest ship, believed to be a transport, from apointblank range, 800yd (730 m). The target, which carried a large deck cargo, took one hit aft and one under her stack. The submarine went deep, received a shortdepth charge attack, and came up to periscope depth to learn that her target had gone down. On21 November , "Trigger" sighted a cargoman and closed to 2000 yards (1800 m) before firing four torpedoes. Two hits started the victim down by the bow as the submarine's crew took turns at the periscope to watch "Eizan Maru" sink. More than a fortnight later, the submarine arrived atPearl Harbor on8 December 1943 .Eighth patrol: January–February 1944
"Trigger" stood out to sea on
New Year's Day 1944 to begin her eighth war patrol, this time in theTruk -Guam shipping lanes. On27 January , she sighted the conning tower of an "Ro"-class submarine dead ahead. "Trigger" set up to fire a bow shot from convert|800|yd. She came to periscope depth and saw the Japanese submarine, then less than convert|100|yd away, was preparing to attack. "Trigger" went to convert|150|ft|-1, expecting a torpedo at any minute, but sound heard no torpedo screws. She came up to periscope depth and saw the Japanese periscope so she decided to make an end around. When "Trigger" returned to periscope depth, the enemy had disappeared.Four days later, she contacted a convoy of three ships accompanied by two "Fubuki"-class destroyers. The submarine scored two hits on the coastal
minelayer "Nasami" which disappeared in a cloud of smoke and debris. The nearer destroyer began closing the range, and "Trigger" missed it with four aft tubes. She caught up with the convoy again and fired five torpedoes at the last ship. Two hits produced flames that reachedmasthead height and several secondary explosions that marked the end of the 11,933-ton convertedsubmarine tender "Yasukuni Maru". Over three weeks later, the submarine terminated the patrol when she arrived atPearl Harbor on23 February .Ninth patrol: March–May 1944
On
23 March , "Trigger" (in the able hands of CommanderFrederick J. "Fritz" Harlfinger II {Class of 1935}, still with "Ned" Beach as exec) headed for thePalau Islands on her ninth war patrol. In the early morning of8 April , she contacted a convoy of approximately 20 large ships with an estimated 25 escorts and closed to attack. When she raised her periscope, she saw a destroyer convert|150|ft|m away firing at the scope and attempting to ram. The submarine loosed four torpedoes at the convoy and went deep as several more escorts joined the attack. On her way down, she heard four explosions. "Trigger" ran at convert|300|ft|m or more for 17 hours as six escorts dogged her trail and rained down numerousdepth charge s. Six exploded extremely close. When the submarine surfaced, her forward torpedo room was flooded to her deck plates, the hull air induction and most compartments were in about the same condition. The bow planes, trim pump, sound gear, and both radars were all dead. Her radio antenna was grounded, and the submarine could not transmit. The crew spent the next four days making repairs "by use of spares, baling wire, and considerable ingenuity."Fact|date=February 2007"Trigger" met submarine USS|Tang|SS-306|3 on
14 April and exchanged information by line gun. The next day, "Trigger"’s executive officer went on board "Tang" by a rubber boat, to borrow an air compressor part and to make plans for a coordinated search and attack. On18 April , "Tang"’s executive officer delivered spare parts for the air compressor to "Trigger", and she continued on patrol.Shortly before midnight on
26 April , the submarine contacted a convoy of six ships off the easternPalau Islands . She fired six torpedoes, from convert|2400|yd, at four ships that were closely bunched and overlapping. Four hits were seen and heard from a big explosion on each ship. Suddenly, a terrific explosion blew up one of the closer ships. One of the more distant ships stood straight up on her bow and then sank immediately. At six minutes after midnight, "Trigger" fired three torpedoes at a group of ships and heard one timed explosion. At 01:57, she fired four torpedoes at a damaged cargo ship and two at an escort. The cargo ship received two more hits. Five minutes later, the submarine fired three stern tubes at a group of three escorts, and the middle one disappeared in a cloud of smoke. During the attack, "Trigger" sank the 11,739-ton passenger-cargo ship "Miike Maru" and heavily damaged the destroyer escort "Kasado", the 9467-ton cargo ship "Hawaii Maru", and the 8811-ton cargo ship "Asosan Maru". "Trigger" returned toPearl Harbor on20 May and four days later, headed for theUnited States for a major overhaul. She arrived atSan Francisco, California , on31 May and, after overhaul, returned toHawaii on11 September .Tenth patrol: September–November 1944
On
24 September , "Trigger" got underway to take station off the east coast of Formosa and perform life guard patrol for bomber strikes due on12 October . The morning of the strikes, she rescued a pilot fromaircraft carrier USS|Bunker Hill|CV-17|3 whose burning plane had crash-landed nearby. On19 October , as the invasion of thePhilippines was about to begin, she contacted a convoy of two "Takao"-classheavy cruisers , one "Nagara"-classcruiser , two other light cruisers, and several destroyers with air cover. "Trigger" had no chance to fire but reported the contact. On30 October , she fired four torpedoes at a tanker but missed. She then fired another four from her stern tubes and heard one hit the target before running up the periscope to watch the other three blow off part of the stern, but the ship did not sink. "Trigger" went deep as 78depth charge s were rained down on her within the next hour, but caused no damage. The damaged 10,021 ton tanker "Takane Maru" was later sunk by submarines USS|Salmon|SS-182|3 and USS|Sterlet|SS-392|3. The next morning, "Trigger" received word from "Salmon" that she had been heavily damaged bydepth charge s and was unable to submerge. "Trigger" rendezvoused with "Salmon" that night and was joined by USS|Silversides|SS-236|3 and "Sterlet" to escort the damaged submarine toSaipan . They were provided with air cover from theMariana Islands and arrived atTanapag Harbor on3 November . A week later, "Trigger" departed with six other submarines but was ordered to discontinue her patrol on17 November and returned toGuam .Eleventh patrol: December 1944–February 1945
On
28 December 1944 , "Trigger" headed for the Bungo Suido-Kii Suido area to begin her 11th war patrol. At 21:05 on3 January 1945 , she sighted a light, and radar made a doubtful contact. Thirty minutes later, a torpedo passed by her starboard side. She reversed course and cleared the area but returned two days later. That day, she sighted a periscope at convert|2000|yd, and—realizing that instead of hunting, she was being hunted—she slipped away.On
29 January , she made radar contact from convert|23000|yd on a large convoy with six escorts and well covered by aircraft. As she closed, the moon came out bright and clear. An enemy bomber turned and started in as radar picked up another plane coming in astern at convert|5000|yd. The submarine went deep, and the convoy slowly pulled away. The next day, the ship was ordered to terminate her patrol, and she returned toGuam on3 February .Twelfth patrol: March 1945
"Trigger" (with new skipper Commander David R. Connole) stood out to sea on
11 March to begin her 12th war patrol and headed for theNansei Shoto area. On18 March , she attacked a convoy west of the islands, sinking the cargo ship "Tsukushi Maru No.3" and damaging another. The attack was reported on20 March , and the submarine was subsequently ordered to radio as many movements of the convoy as possible to help find a safe passage through a known mined area of theEast China Sea . On24 March , "Trigger" was ordered to begin patrolling west of the islands the next day, outside the 100 fathom curve, and to steer clear of restricted areas. On26 March , she was ordered to join a wolf pack called "Earl's Eliminators" and to acknowledge receipt of the message. A weather report came from the submarine that day but no confirmation of her having received the message. The weather report was "Trigger"'s last transmission. On4 April , she was ordered to proceed toMidway Island , but she had not arrived by1 May and was reported as presumed lost.Postwar records indicate she torpedoed and sank the repair ship "Odate" on
27 March . The next day, Japanese planes and ships joined in a two-hour attack on a submarine heard by "Silversides", USS|Sea Dog|SS-401|3, USS|Hackleback|SS-295|3, and USS|Threadfin|SS-410|3 in adjacent areas. "Threadfin" was the only one of these submarines attacked that day, and she reported hearing manydepth charge s and several heavy explosions east of her after the attack on her ceased. Postwar Japanese records showed a Japanese aircraft detected and bombed a submarine on28 March 1945 . Surface ships were then guided to the spot and delivered an intensive depth charging. After two hours, a large oil slick appeared."Trigger" was stricken from the
Naval Vessel Register on11 July 1945 ."Trigger" was immortalized and eulogized in Beach's 1952 book "Submarine!".
Awards
"Trigger" received 11
battle star s forWorld War II service and the Presidential Unit Citation for her fifth, sixth, and seventh war patrols. She is credited with sinking 18 ships (tied for seventh on the list of confirmed sinkings by number of ships with USS|Seawolf|SS-197|2 and USS|Rasher|SS-269|2), totaling 86,552 tons (seventh on the list of confirmed sinkings by tonnage), according to the officialJANAC accounting postwar.;Citation: "For outstanding performance in combat during her Fifth, Sixth, and Seventh War Patrols against the enemy. Employing highly daring and hazardous tactics, the USS TRIGGER struck at the enemy with consistent aggressiveness, seeking out and pursuing her targets with dogged determination regardless of unfavorable attack conditions. Her exceptionally notable record of severe damage inflicted on hostile shipping and the gallant fighting spirit of her officers and men reflect great credit upon the United States Naval Service."

The "Trigger" Maru
:"I'm the Galloping Ghost of the Japanese Coast"::by Constantine Guinness, Motor Machinist's Mate First Class (MOMM 1/c), United States Navy
:I'm the galloping ghost of the Japanese coast. :You don't hear of me and my crew :But just ask any man off the coast of Japan. :If he knows of the Trigger Maru. :I look sleek and slender alongside my tender.:With others like me at my side, :But we'll tell you a story of battle and glory, :As enemy waters we ride. :I've been stuck on a rock, felt the depth charge's shock,:Been north to a place called Attu,:and I've sunk me two freighters atop the equator :Hot work, but the sea was cold blue. :I've cruised close inshore and carried the war :to the Empire Island Honshū, :While they wire Yokahama I could see Fujiyama, :So I stayed, to admire the view. :When we rigged to run silently, deeply I dived, :And within me the heat was terrific. :My men pouring sweat, silent and yet :Cursed me and the whole damned Pacific. :Then destroyers came sounding and depth charges pounding :My submarine crew took the test.:Far in that far off land there are no friends on hand, :To answer a call of distress. :I was blasted and shaken (some damage I be taken), :my hull bleeds and pipe lines do, too :I've come in from out there for machinery repair, :And a rest for me and my crew. :I got by on cool nerve and in silence I served, :Though I took some hard knocks in return,:One propeller shaft sprung and my battery's done, :But the enemy ships I saw burn. :I'm the galloping ghost of the Japanese coast, :You don't hear of me and my crew. :But just ask any man off the coast of Japan, :If he knows of the Trigger Maru.See also
