Red Sun Setting, page 4
On 13 June the destroyer Melvin met the RO-36 near Saipan and pelted the sub with 5-inch fire and depth charges. The destroyer Wadleigh, with help from the Melvin, sent the RO-114 down on the 16th. The next day a Liberator of VB-109, flying out of Eniwetok, bombed and sank the RO-117 cruising on the surface. Another surfaced submarine, the I-184, ran afoul of an Avenger from the escort carrier Suwannee on 19 June and never returned to Japan to report the attack. A total of eleven Japanese submarines had been lost so far. Six more were to be sunk during this period, and all six belonged to the destroyer escort England.
The England, commanded by Lieutenant Commander Walton B. Pendleton, was a brand-new ship with only about ten weeks sea experience. At Purvis Bay (on Florida Island across Ironbottom Sound from Guadalcanal) she was assigned to Escort Division 39 along with the destroyer escorts Raby and George. The officer in tactical command (OTC) was Commander Hamilton Hains, riding in the George. Armed with excellent information on the NA line provided by American codebreakers, the three ships left Purvis Bay on 18 May and headed north to attack the line. However, the first unfortunate to test the England’s inexperienced crew was not a member of the NA line, but a submarine on a supply mission to Bougainville. At 1335 on the 19th, the England picked up the sub (the I-16) on her sonar. Five hedgehog attacks were made with hits being made on the second and fifth runs. Following the last attack, a violent explosion threw men to the deck and lifted the England’s fantail out of the water. At first the England’s crew thought they had been torpedoed; then they realized the I-16 had blown up.
Early on the morning of the 22nd the three destroyer escorts ran across the RO-106 cruising on the surface. The Japanese submarine dove, but it could not escape. When the George’s first attack was unsuccessful, the England took over and sent the enemy submarine to the bottom with two hedgehog salvos. Twenty-four hours later the RO-104 became the quarry. Detected on the surface, she plunged and then played cat and mouse with the Raby and George. As the hunters closed the wily submarine skipper “pinged” back at his “pinging” attackers, hoping to foul up their runs. He also maneuvered his vessel skillfully. The Raby spent over half an hour in fruitless attacks, and the George made five runs without hitting anything. Finally tiring of the game, the OTC ordered the England in. Her first pass was unsuccessful but on the second her hedgehogs tore the RO-104 apart. Shortly after this action another enemy submarine was detected, but this one was lucky; it escaped.
By this time Commander Charles A. Thorwall, commanding Escort Division 40 and riding in the England, was ready to change the England’s call sign from “Bonnie” to “Killer-Diller.”9
Moving south toward Manus, the three little ships had still more excitement ahead for them. A little after midnight on the 24th the George’s radar locked onto a surface target, range 14,000 yards. The target submerged, but at 0150 sonar contact was made. The captain of this sub was good, too—but not quite good enough. The England was forced to make two dry runs because of shrewd evasive tactics by the enemy skipper, but the third pass scored. At least three hedgehogs hit and only bits and pieces of the RO-116 surfaced again.
On 25 May this crack hunter-killer group received orders to proceed to Seeadler Harbor in the Admiralties, to refuel and load more hedgehogs. At 2303 the Raby’s radar picked up another sub 14,000 yards away. Within minutes the other two ships also had the target. When the range closed to 4,000 yards the sub dove. Sonar contact was quickly made, and the Raby was given first chance this time, but she muffed it. The England didn’t. Her first salvo snuffed out the RO-108’s life some 250 feet below the surface. At daybreak oil and debris were discovered gushing to the surface.
Arriving at Seeadler Harbor on the afternoon of the 27th, the three ships loaded more hedgehogs from their sister destroyer escort, the Spangler, which now joined them. After fueling, the four ships sortied the next afternoon to join a hunter-killer group built around the escort carrier Hoggatt Bay. Escorting the carrier were the destroyers Hazelwood and McCord.
Early on the morning of the 30th, as the task group was steaming north, the Hazelwood made radar contact with the RO-105. The destroyer forced the sub to dive, but a depth-charge attack gave no conclusive results. The Hazelwood maintained contact until 0435 when the Raby and the George arrived to assist. The two destroyer escorts were asked to make attacks while the McCord acted as contact keeper. (These two destroyer escorts were still part of Escort Division 39, while the England and the Spangler were now Escort Division 40 under the command of Commander Thorwall.) By now the other destroyer escorts were getting an inferiority complex, so Commander Hains was trying to give them a chance at a kill. The Raby and George each made a number of passes over the unlucky RO-105 and several explosions indicated the sub was hit. But it was apparently only wounded. The two ships spent the rest of the day holding the RO-105 down.
Shortly after the sun dipped below the horizon, the Americans heard three heavy underwater explosions. No debris or oil floated to the surface, so it was thought the Japanese skipper had become cagy and had fired torpedoes to throw his pursuers off the track. The ruse did not work, for contact was soon regained and maintained the rest of the night. By now the task group really wanted this submarine, but it was decided to wait until daylight to make any more attacks.
When dawn broke the George, followed by the Raby and Spangler, attacked. They all missed. Time was growing short, for the ships had received word to clear the area, as they might get jumped by enemy planes. Finally, the OTC called in the England. This young “old pro” did not miss. At 0729 on the 31st her sonar operator reported contact with the sub. Six minutes later a full salvo of hedgehogs connected with the enemy vessel. A huge explosion followed and the RO-105 went down for the last time. Only an oil slick and a few pieces of debris marked her passing.
Six Japanese submarines had been sunk by the England in thirteen days. It was a masterful performance which earned the ship a Presidential Unit Citation. Commander Thorwall congratulated the England and her crew with the comment, “As a result of your efforts Nip recording angel working overtime checking in Nip submariners in joining Honorable Ancestors.”10
The submarine phase of Operation A-GO had completely miscarried. Not only were seventeen submarines lost, but no submarines would now be available for quick action against the U.S. fleet off the Marianas. The destruction of the NA line and other losses in the area also tended to lead Japanese officers back to their preconceived opinion that any American attack would be launched at the Palaus.
The Japanese were now rapidly becoming aware that a major American offensive was at hand. But where? Even with the submarine losses south of Truk indicating a drive west from there, more substantial evidence was needed. Task Group 58.6, consisting of the carriers Essex, Wasp, San Jacinto, five cruisers, and twelve destroyers, struck Marcus on 19 and 20 May. Results were not overwhelming, but the attack prompted Admiral Toyoda to place TO-GO in motion. However, when TG 58.6 raided Wake on the 23rd it was obvious that these two forays were not full-scale attacks and Toyoda cancelled TO-GO.11
Toyoda issued his preparation order for A-GO on 20 May. The Mobile Fleet was placed on a six-hour alert. Falling back on one of their favorite tactics, the “bait” force, the Japanese commanders ordered the battleship Fuso, cruisers Myoko and Haguro, and a pair of destroyers to be ready to sortie as a decoy force. They were to lure the Americans into the Palau–Ulithi area where they could then be destroyed by naval and air forces concentrated there. Finally, Base Air Force was ordered to intensify its reconnaissance efforts.
Base Air Force conducted several reconnaissance flights over American bases. On 27 May one plane flew from Truk via Buin (thought by the Americans to be knocked out) to Tulagi, where Rear Admiral Richard L. Conolly’s Southern Attack Force was staging for the Guam landing phase of the Marianas invasion. Two other Truk-based planes staged through Nauru to take a look at Majuro and Kwajalein, where most of the invasion forces were gathering. The day before TF 58 sortied from Majuro another intrepid pilot took a peek at the lagoon and reported an impressive array of warships there. The Japanese now had the Americans located, but they were not quite sure of what to do next.
Following the receipt of “Start A-GO,” which actually meant “Begin preparations,” Admiral Ozawa held a meeting on his flagship Taiho for all his commanders. He reminded them that the coming action was to be decisive, and that they were to press on despite any damage suffered. Regarding the latter point, Ozawa declared that for A-GO to succeed, individual units had to be considered expendable. The officers present also discussed proposed tactics for the battle. A massed grouping of carriers much like the disposition used by the Americans was considered, or an “encirclement” using an inverted-V arrangement of three groups. But the final disposition chosen for the Mobile Fleet involved dividing the force into a Main Body and a heavily armed Vanguard.12
The Japanese now watched and waited. Then came the invasion of Biak on 27 May. The Japanese high command felt that this move should not go unchallenged. In the first place, the loss of the three airfields on this island off the coast of New Guinea would be a serious blow to the air units of A-GO. The Japanese also reasoned that an attempt by them to recapture Biak would lure the U.S. fleet into “The Decisive Battle near Palau.” But the Combined Fleet intelligence officer, Commander Chikataka Nakajima, was not convinced Biak was the major offensive. He thought the landings were just a subsidiary operation and the main American effort would be aimed at the Marianas. His superiors did not agree with him, though, and the Japanese prepared a relief operation for Biak designated Operation KON. The KON plan called for warships to transport about 2,500 troops to Biak from Mindanao. The battleship Fuso, the heavy cruisers Myoko and Haguro, and five destroyers were to act as the screen for a transport section of one heavy and one light cruiser, and three destroyers.
The movement of the enemy ships, coming mainly out of Tawi Tawi, did not escape notice. Allied intelligence officers, using “Magic” intercepts, already knew that a landing attempt would be made on Biak around the fourth or fifth of June and that the Fuso, Myoko, and Haguro would be in the force. The reports by the submarines Cabrilla and Bluefish of enemy vessels leaving Tawi Tawi merely confirmed the “Magic” reports.13
The transport section, now augmented by two minelayers and a small transport, picked up its troops at Zamboanga on 31 May and proceeded to Davao, where it rendezvoused with the heavy cruisers and three destroyers. The units then headed for Biak, the Fuso and two destroyers taking a more northerly course. On the morning of 3 June the submarine Rasher spotted part of the force and sent off a contact report. The message was intercepted by the Japanese, who were disturbed at being discovered so far from their target. When a Wakdebased PB4Y began shadowing them, the Japanese decided to call off the attempt.
But this abortive effort would not end happily for the Japanese. While the transport section proceeded to Sorong, on New Guinea’s western tip, to disembark troops, the Fuso, Myoko, Haguro, and two destroyers retired to Davao. As this force approached Davao on the night of 8 June, they ran into the path of the submarine Hake. Commander John C. Broach waited until a destroyer crossed his sights, then fired a spread of torpedoes that ripped open the 2,077-ton Kazagumo and sank her.
While the first attempt to reinforce Biak by sea had stalled, action in the air over the island had heated up considerably. Since the Japanese had been anticipating that the next major U.S. offensive would be in the Carolines—Palaus sector, much of their air strength was situated in or near this region. When the Biak landings “confirmed” their suspicions, they began rushing planes in to reinforce their 23rd Air Flotilla. A number of these planes came from the Marianas—reducing the air strength there at a time when they would most be needed.
This one fact illustrates the effectiveness of the Joint Chiefs’ concept of a dual thrust across the Pacific. No longer could the Japanese mass their forces in a particular area against an enemy thrust, for now they could be outflanked by another enemy movement.
A number of air strikes were flown against U.S. positions on Biak and Wakde; one attack in particular, on 5 June at Wakde, was very successful. But the Japanese could not keep up the intensity of their attacks and in the process lost planes that could have been used more profitably elsewhere. Also, quite a few pilots came down with malaria at this time, greatly limiting their usefulness.
The Japanese were not about to give up on Biak, though, and a second attempt to reinforce it was quickly mounted. On 7 June Rear Admiral Naomasa Sakonju led a force of six destroyers, distantly screened by two cruisers, on the reinforcement mission. Three destroyers carried six hundred troops, while the remaining destroyers provided an escort and also towed a landing barge each.
Sakonju’s second effort (he had led the first attempt) was to be even less successful. On the 8th ten B-25s from Hollandia, escorted by P-38s, spotted Sakonju’s ships sliding in toward Biak. In a low-level bombing and strafing attack, the B-25s sent the 1,580-ton Harusame to the bottom and damaged the Shiratsuyu, Shikinami, and Samidare. Sakonju pressed on, but not for long. At 2340 a lookout on one of Sakonju’s ships picked up an Allied cruiser and destroyer force, led by Rear Admiral Victor A. C. Crutchley, RN, which was out looking for just these ships.
Sakonju decided that discretion was the better part of valor. After casting off the barges, his force fired a volley of torpedoes at the Allied ships and then high-tailed it to the northwest. Involved in a stern chase and having to dodge torpedoes occasionally, the Allied destroyers were unable to close the distance enough to be effective. The Shigure was hit five times by 5-inch fire and the Shikinami also had some casualties, but that was the extent of damage to both sides. Most of the troops—who must not have been very happy about what was taking place around them—were taken back to Sorong. The second attempt to reinforce Biak had been turned back.14
While the Japanese were vainly trying to reach Biak, a lone U.S. submarine was making her presence felt near Tawi Tawi. Commander Samuel D. Dealey was on his fifth patrol in the Harder. This patrol he had been assigned a dual mission: scout Tawi Tawi and pick up a group of guerrillas on northeast Borneo.
As the Harder was transiting Sibutu Passage (just south of Tawi Tawi) on the night of 6 June, a convoy of three tankers and two destroyers was picked up. Closing the convoy on the surface, the sub was suddenly spotlighted for the nearest destroyer, when the moon broke through the clouds. The Japanese destroyer charged in for an “easy” kill. Dealey waited until the enemy ship was only 8,500 yards away before submerging. When the ship got within 1,100 yards, Dealey let her have three “fish” from the stern tubes. The Minazuki, a 1,590-ton vessel, was stopped cold by two torpedoes, blew up, and went down fast. A second try at the convoy by the Harder was frustrated by the other destroyer, and Dealey turned back toward Sibutu Passage.
Shortly before noon the next day, Dealey saw another destroyer in the Passage. And the destroyer saw the Harder! This time Dealey let the 2,077-ton Hayanami come in close to point-blank range—650 yards—before firing three torpedoes “down the throat.” Two of them disembowled the Hayanami, and nine minutes after the first sighting she sank, stern first. But Dealey and the Harder were not home free. A second destroyer came boiling over to the spot and spent the next two hours rolling depth charges around the sub. None hit, but when six more Japanese destroyers showed up, Dealey decided it was time to leave. He cleared the area and on the night of 8 June picked up his group of guerrillas. He then returned through Sibutu Passage and took up station off Tawi Tawi.
Two more Japanese destroyers showed up in the Harder’s periscope the following night. Dealey made a submerged approach on the ships and when the targets overlapped, he fired four torpedoes. Two hit the 2,033-ton Tanikaze, which literally fell apart. The other two “fish” were thought to have hit the second destroyer, but there is no record of this ship being lost or even damaged.
Dealey and the Harder had made a big dent in Ozawa’s destroyer forces. Three destroyers had been sent to the bottom in four days by “The Destroyer Killer” (as Dealey was later nicknamed). The U.S. submarines congregated around Tawi Tawi had hurt Ozawa and, thus, Operation A-GO. Along with the destroyers Dealey had sunk, several others had been lost or would soon be. Destruction of these destroyers would mean that the Mobile Fleet would be inadequately screened by these critically important, versatile ships during the coming battle. It was a situation other American submarines would take advantage of in the Philippine Sea.
In the meantime, following the second failure to reinforce Biak, Ozawa was more determined than ever to force his way to the island and land troops that would push the invaders back into the sea. To this end he assembled a new force to carry out Operation KON. It was not a puny force. Included in it were the superbattleships Yamato and Musashi, three heavy and two light cruisers, seven destroyers, two minelayers, and a number of support and transport vessels.
Under the command of Vice Admiral Matome Ugaki, this force sortied from Tawi Tawi on the afternoon of 10 June. Their departure was noted by Sam Dealey. As the Harder closed in for an attack, the sub’s periscope was seen and a destroyer charged in. Dealey was not impressed and waited for the enemy ship to close the range. At 1,500 yards three torpedoes were fired “down the throat.”
As the Harder went deep, a series of explosions were heard. Dealey thought he had gotten another destroyer, but Japanese records do not confirm this. If not sunk, this unidentified destroyer must have been badly damaged. The other escorts and covering aircraft were not about to let the Harder off the hook, but she did escape after undergoing a succession of furious counterattacks. After dark, Dealey was able to surface and send a contact report about the enemy’s departure from Tawi Tawi.
