Leyte Gulf

Relief map of Leyte Gulf and surroundings

Leyte Gulf is a somewhat exposed anchorage on the eastern edge of the Philippines, with a small port at Tacloban on Leyte. It was the site of an American invasion in October 1944 that led to a full-scale naval battle between the U.S. and Japanese fleets.

Battle of Leyte Gulf

Command arrangements for the Leyte campaign were muddled, as the Philippines lay close to the theater boundaries for the Southwest Pacific Area, Pacific Ocean Areas, and China-Burma-India theaters. Although MacArthur commanded Kinkaid's 7 Fleet in immediate support of the landing operations, distant cover was provided by the fast carriers of 3 Fleet, which was the main striking force of Pacific Fleet under Nimitz. This divided command would have important consequences during the battle. In particular, Halsey was under orders to make the destruction of the Japanese Fleet, not the protection of the amphibious forces, his highest priority.

The Japanese contingency plan for the defense of the Philippines, Sho-go, was activated on 22 October 1944 when word reached Tokyo that the Americans had begun landings at Leyte. Due to massive attrition and lack of fuel, the Japanese had virtually no aircraft and pilots for their remaining carriers (under the command of Ozawa), but they still had powerful surface forces (under Kurita) built around the Yamato and Musashi. These were based at Singapore in order to be close to their fuel supplies, while the carrier forces remained in the Inland Sea. In order to give Kurita a chance to reach and destroy the American amphibious force, Ozawa was ordered to deliberately allow his force to be spotted and pursued by 3 Fleet under Halsey. Kurita was to split his force, taking the main body through San Bernardino Strait north of Leyte Gulf while a detachment under Nishimura would enter Leyte Gulf through Surigao Strait to the south. Nishimura was  to be joined by Shima, who was coming south with a small force of cruisers and destroyers after eluding a trap set by Halsey off Formosa.

The Japanese plan was overly complex and went badly from the start. Kurita's force was discovered off Palawan on 23 October 1944 by submarines Darter and Dace, which sank Atago and Maya and severely damaged Takao. The American submarine commanders found their approach simplified by the low speed of Kurita's force, just 16 knots, and by Kurita's failure to station any picket destroyers ahead of his main force. Their contact report was the first indication to Allied intelligence that the main strength of the Japanese Navy was coming out to contest the Leyte landings. However, Darter ran aground in the poorly charted reefs of Palawan while maneuvering for a second attack (there had been no opportunity for a navigational fix in over 24 hours) and had to be scuttled, her crew being taken off by Dace.

The next few days saw the largest fleet action in history. Historians have generally divided the battle into four major engagements and a number of lesser engagements.

Battle of the Sibuyan Sea. All through 24 October 1944, Kurita's force was hammered from the air by strikes from Halsey's carriers. The giant battleship Musashi sank after taking 17 bomb hits and 19 torpedo hits. Her commander attempted to beach her, but she capsized at 1935 with 1,096 of her crew. Battleships Yamato and Nagato each took two bomb hits that inflicted significant damage to their upper works, hindering fire control and communications, and heavy cruiser Myoko took a torpedo hit that damaged two shafts and forced her to withdraw   Fighter protection from land bases was nonexistent, and the Japanese antiaircraft fire, while voluminous, was largely ineffective. Just 18 Allied aircraft were shot down out of 259 sorties against the Japanese force.  At 1600, Kurita finally reverse course while broadcasting pleas for help.

While the American combat air patrol was successfully driving off a Japanese strike of about 60 aircraft, a single Judy dive bomber broke through the cloud cover and put its bomb through the flight deck of light carrier Princeton. The blast ignited gasoline in the hangar deck and the flames began detonating torpedoes loaded on TBF Avengers. The crew fought the fire for almost six hours before the flames reached the torpedo magazine and a massive explosion blew up the stern of the ship. There were heavy casualties on cruiser Birmingham, alongside assisting with firefighting, and Princeton was scuttled shortly thereafter.

Meanwhile, Ozawa was trying to be detected by the Americans, unaware that his radio transmitter was malfunctioning and preventing his radio traffic from being heard by either friend or foe.  The Americans finally spotted him at 1540, and Halsey, overestimating the damage to Kurita's force and believing it was retiring for good, took off in hot pursuit of Ozawa with all his forces. Now it was the Americans whose plans were thrown into confusion. Halsey had transmitted a contingency plan for detaching his battle line as Task Force 34 to guard San Bernardino Strait. However, with Kurita seemingly in retreat, Halsey decided this was unnecessary. But the original message was the only one seen by other commanders (principally  Kinkaid with 7 Fleet in Leyte Gulf) and they were left with the mistaken impression that San Bernardino Strait was being watched.

At 1935 a night reconnaissance flight from Independence found that Kurita's force had returned to a course for San Bernardino Strait. It is unclear why Halsey did not then detach Task Force 34 to cover the strait. Mitscher, possibly smarting from having been bypassed all day by Halsey (who issued orders directly to Mitscher's task group commanders), declined to radio such a recommendation to Halsey. Three of Halsey's task force commanders also wondered at the order, and Bogan went so far as to contact Halsey's staff with the information that the navigation lights in San Bernardino Strait were lit. He was brushed off, and made no further protest. Lee, the battle line commander, correctly deduced that Ozawa's force was a decoy with little striking power, but his signal to Halsey warning that Kurita was likely to come out of San Bernardino Strait was also brushed off. Halsey's failure to guard the strait must be judged one of the great blunders of the Pacific War.

Battle of Surigao Strait. Nishimura's force was sighted around 0950 on 24 October, but no strikes were launched against him and no further sightings were made that day. However, Kinkaid correctly guessed Nishimura's intentions to come through Surigao Strait during the night. Thinking his rear was covered, he ordered Oldendorf to take the heavy units of 7 Fleet to lay an elaborate trap for Nishimura's force. Nishimura's ships were attacked by waves of PT boats and destroyers even before coming within range of Oldendorf's waiting battle line. Only one destroyer escaped out of the original force of two battleships, a cruiser, and four destroyers.  Shima, the admiral who previously eluded Halsey's trap off Formosa, encountered the shattered remnants of Nishimura's fleet and prudently withdrew.

Battle off Samar. Meanwhile, Kurita had reversed course again and slipped through San Bernardino Strait, albeit seven hours later than the Japanese had originally planned. He found to his surprise that the strait was unguarded. As dawn broke, his lookouts spotted several escort carriers protected by destroyers and destroyer escorts, which he mistook for fleet carriers protected by cruisers and destroyers. The American ships were completely outgunned and at least twelve knots slower than Kurita’s cruisers, but fought fiercely, and American aircraft in the area made repeated passes against Kurita’s ships even after expending whatever munitions they were carrying. Kurita believed he was up against much stronger forces than was the case, and retreated back through San Bernardino Strait after sinking three destroyers and an escort carrier. He left one of his own cruisers sinking.

At about the same time, land-based air units carry out the first kamikaze attacks of the war, sinking the escort carrier St. Lo and badly damaging two others.

Battle of Cape Engano. Meanwhile, Halsey was in the process of annihilating Ozawa’s force (he had already sunk Chitose and Chiyoda) when a message reached him from Nimitz in Hawaii. The original message was a simple query: “Where is Task Force 34?” However, Nimitz’ communications technician, sensing a certain urgency in the query, saw fit to slightly strengthen the message. A further gaffe occurred due to a poor choice of padding: Like all coded U.S. messages, the message had been padded at its beginning and end with phrases that were supposed to be nonsense. The end padding sufficiently resembled part of the message that it was left in place by Halsey’s decoders, and the message ultimately handed to Halsey read: “WHERE IS RPT WHERE IS TASK FORCE 34 XX THE WORLD WONDERS”. Halsey reportedly threw his hat on the deck and started weeping with rage, then returned with his battleship force and one of his carrier task forces to San Bernardino Strait — too late to catch Kurita. It hardly mattered; the Japanese Navy was practically finished as a fighting force. Halsey's other two carrier task groups were able to finish off carriers Zuiho and Zuikaku and sink an additional cruiser and two destroyers before they, too, were forced to break off the pursuit.

The Battle of Leyte Gulf was a decisive American victory, yet it did not reflect all that well on the Americans, who had overwhelming superiority in numbers. Halsey's blunder (few historians now call it anything else) was the most serious mistake on the American side, but most of the men of 3 Fleet were exhausted from prolonged operations and it showed. The air strikes against Kurita on 24 October 1944 scored only 45 hits with 259 strike aircraft. On the other hand, the Japanese performance was even worse than that of the Americans. Kurita badly mismanaged the battle off Samar even before giving the command to retreat, and the Japanese gunfire against the American escort carriers was notably inaccurate. The battle resembled the final round of a heavyweight prize fight, with both boxers barely able to remain on their feet.
