The Battle of Leyte (; ; ) in the Pacific campaign of World War II was the amphibious invasion of the island of Leyte in the Philippines by American forces and Filipino guerrillas under the overall command of General Douglas MacArthur. The combined forces fought against the Imperial Japanese Army in the Philippines led by General Tomoyuki Yamashita. The operation, codenamed King Two,Cutler, Thomas J., The Battle of Leyte Gulf: 23–26 October 1944, Naval Institute Press, 2001, p. 52 launched the Philippines campaign of 1944–45 for the recapture and liberation of the entire Philippine Archipelago and to end almost three years of Japanese occupation.
Background Japan had conquered the Philippines in 1942. Controlling it was vital for Japan's survival in World War II because it secured sea routes to Borneo and Sumatra in which rubber and petroleum were shipped to Japan.
For the U.S., capturing the Philippines was a key strategic step in isolating Imperial Japan's military holdings in China and the Pacific theater. It was also a personal matter of pride for MacArthur. In 1942, just a month before Japan forced the surrender of all USAFFE forces in the Philippines, U.S. President Franklin D. Roosevelt had ordered MacArthur to leave the Philippines and organize the U.S. forces gathering in Australia, which were meant to relieve the USAFFE. Those relief forces were non-existent; Roosevelt's true intentions in ordering MacArthur to flee the Philippines had been to prevent his capture by the Japanese. Still, MacArthur had vowed that he would return to the Philippines. He repeatedly stated that it was a moral obligation of the U.S. to liberate the Philippines as soon as possible. In March 1944, the Joint Chiefs of Staff ordered MacArthur to plan an attack on the southern Philippines by the end of the year, and Luzon in early 1945. In July 1944, Roosevelt met with MacArthur and Chester Nimitz in Hawaii, where the decision was made to invade the Philippines, from which land air bases could be used for the Pacific Theater of Operations.
Over the summer of 1944, planes from the aircraft carriers of the U.S. 3rd Fleet under Admiral William F. Halsey carried out several successful missions over the Philippines and found weak Japanese resistance. Halsey then recommended a direct strike on Leyte, canceling other planned operations, and the Leyte invasion date moved forward to October.
Leyte, facing the Pacific Ocean, has numerous deep-water approaches and sandy beaches which offered opportunities for amphibious assaults and fast resupply. The roads extend inland with Highway 1, that runs for along the east coast between Abuyog town to the north and the San Juanico Strait between Leyte and Samar Islands, providing avenues for tank-infantry operations, as well as suitable ground for airfield construction. American air forces based on Leyte could strike at enemy bases and airfields anywhere in the Philippines.
A heavily forested mountain range dominates the interior and separates two plains. The larger Leyte Valley extends from the northern coast to the long eastern shore and contains most of the towns and roadways on the island. The other, Ormoc Valley, situated on the west side, was connected to Leyte Valley by Highway 2 running from Palo town on the east coast, then west and then south through Leyte Valley to Ormoc bay, then along the western shore to Baybay. The road then turned east to cross the mountainous interior and connected it with Highway 1 on the east coast at Abuyog. South of these towns, the mountainous southern third of Leyte was mostly undeveloped. High mountain peaks over , as well as the jagged karst formations of the island offered formidable defensive opportunities. The timing late in the year forced combat troops and supporting pilots, as well as logistical units, to contend with monsoon rains.
Leyte's population of over 900,000 people—mostly farmers and fishermen—could be expected to assist an American invasion, since many residents already supported the guerrilla struggle against the Japanese. Japanese troop strength on Leyte was estimated by U.S. intelligence at 20,000; mostly of the 16th Division under Lieutenant General Shiro Makino.

Landings Preliminary operations for the Leyte invasion began at dawn on 17 October 1944, with minesweeping tasks and the movement of the 6th Rangers toward three small islands in Leyte Gulf. Although delayed by a storm, the Rangers were on Suluan and Dinagat islands by 08:05 am. On Suluan, they dispersed a small group of Japanese defenders and destroyed a radio station, while they found Dinagat unoccupied. The third island, Homonhon, was taken without any opposition the next day. On Dinagat and Homonhon, the Rangers proceeded to erect navigation lights for the amphibious transports to follow. Meanwhile, reconnaissance by underwater demolition teams revealed clear landing beaches for assault troops on Leyte. Independently, the 21st Infantry Regiment on 20 October landed on Panaon Strait to control the entrance to Sogod Bay.
Following four hours of heavy naval gunfire on A-day, 20 October, Sixth Army forces landed on assigned beaches at 10:00. X Corps pushed across a stretch of beach between Tacloban airfield and the Palo River. to the south, XXIV Corps units came ashore across a strand between San José and the Daguitan River. Troops found as much resistance from swampy terrain as from Japanese fire. Within an hour of landing, units in most sectors had secured beachheads deep enough to receive heavy vehicles and large amounts of supplies. Only in the 24th Division sector did enemy fire force a diversion of follow-up landing craft. But even then the sector was secure enough by 13:30 to allow Gen. MacArthur to make his dramatic entrance through the shore onto Red Beach and announce to the populace the beginning of their liberation: "People of the Philippines, I have returned! By the grace of Almighty God, our forces stand again on Philippine soil."
By the end of A-day, the Sixth Army had moved inland and five miles wide. In the X Corps sector, the 1st Cavalry Division held Tacloban airfield, and the 24th Infantry Division had taken the high ground on Hill 522 commanding its beachheads. In the XXIV Corps sector, the 96th Infantry Division held the approaches to Catmon Hill, and the 7th Infantry Division held Dulag and its airfield.
General Makino spent the day moving his command post from Tacloban, inland to the town of Dagami. The initial fighting was won at a cost of 49 killed, 192 wounded, and six missing. The Japanese counterattacked the 24th Infantry Division on Red Beach through the night, unsuccessfully.
Campaign in the Leyte Valley The Sixth Army made steady progress inland against sporadic and uncoordinated enemy resistance on Leyte in the next few days. The 1st Cavalry Division of Maj. Gen. Verne D. Mudge secured the provincial capital, Tacloban, on 21 October, and Hill 215 the next. On 23 October, Gen. MacArthur presided over a ceremony to restore civil government to Leyte. 1st and 2nd Cavalry Brigades initiated a holding action to prevent a Japanese counterattack from the mountainous interior, after which the 1st Cavalry was allowed to move on. The 8th Cavalry established itself on Samar by 24 Oct, securing the San Juanico Strait.
On the X Corps left, the 24th Infantry Division under Maj. Gen. Frederick A. Irving, drove inland into heavy enemy resistance. After days and nights of hard fighting and killing some 800 Japanese, the 19th and 34th Infantry Regiments expanded their beachhead and took control of the high ground commanding the entrance to the northern Leyte Valley. By 1 November, after a seven-day tank-infantry advance supported by artillery fire, both regiments had pushed through Leyte Valley and were within sight of the north coast and the port of Carigara, which the 2nd Cavalry Brigade occupied the next day after Suzuki ordered a withdrawal. In its drive through Leyte Valley, the 24th Division inflicted nearly 3,000 enemy casualties. These advances left only one major port on Leyte—Ormoc City on the west coast—under Japanese control.
From the XXIV Corps beachhead Gen. Hodge had sent his two divisions into the southern Leyte Valley, which already contained four airfields and a large supply center. Maj. Gen. James L. Bradley's 96th Infantry Division was to clear Catmon Hill, a promontory, the highest point in both corps beachheads, and used by the Japanese as an observation and firing post to fire on landing craft approaching the beach on A-day. Under cover of incessant artillery and naval gunfire, Bradley's troops made their way through the swamps south and west of the high ground at Labiranan Head. After a three-day fight, the 382nd Infantry Regiment took a key Japanese supply base at Tabontabon, inland, and killed some 350 Japanese on 28 October. Simultaneously two battalions each from the 381st Infantry Regiment and 383rd Infantry Regiments slowly advanced up opposite sides of Catmon Hill and battled the fierce Japanese resistance. When the mop-up of Catmon Hill was completed on 31 October, the Americans had cleared 53 pillboxes, 17 caves, and several heavy artillery positions.
