The Philippines Campaign, the Battle of the Philippines or the Liberation of the Philippines (Filipino: Kampanya sa Pilipinas, Labanan sa Pilipinas & Liberasyon ng Pilipinas), (Operation Musketeer I, II, and III) (Filipino: Operasyon Mosketero I, II, at III), was the American and Filipino campaign to defeat and expel the Imperial Japanese forces occupying the Philippines during World War II. The Japanese Army overran all of the Philippines during the first half of 1942. The liberation of the Philippines commenced with amphibious landings on the eastern Philippine island of Leyte on October 20, 1944. United States and Philippine Commonwealth military forces were progressing in liberating territory and islands when the Japanese forces in the Philippines were ordered to surrender by Tokyo on August 15, 1945, after the dropping of the atomic bombs on mainland Japan and the Soviet invasion of Manchuria.

By mid-1944, American forces were only 300 nautical miles (560 km) southeast of Mindanao, the largest island in the southern Philippines – and able to bomb Japanese positions there using long-range bombers. American forces under Fleet Admiral Chester W. Nimitz had advanced across the Central Pacific Ocean, capturing the Gilbert Islands, some of the Marshall Islands, and most of the Marianas Islands, bypassing many Japanese Army garrisons and leaving them behind, with no source of supplies and militarily impotent.
Aircraft carrier-based warplanes were already conducting air strikes and fighter sweeps against the Japanese in the Philippines, especially their military airfields. U.S. Army and Australian Army troops under the American General Douglas MacArthur, the Supreme Commander of the Southwest Pacific Theater of Operations, had either overrun, or else isolated and bypassed, all of the Japanese Army on New Guinea and the Admiralty Islands. Before the invasion of the Philippines, MacArthur's northernmost conquest had been at Morotai in the Dutch East Indies on September 15–16, 1944. This was MacArthur's one base that was within bomber range of the southern Philippines.
U.S. Navy, Marine Corps, and Army as well as Australian and New Zealand forces under the command of Admiral Nimitz and Admiral William F. Halsey, Jr. had isolated the large Japanese South Pacific base at Rabaul, New Britain, by capturing a ring of islands around Rabaul, and then building air bases on them from which to bomb and blockade the Japanese forces at Rabaul into military impotence.
With victories in the Marianas campaign (on Saipan, on Guam, and on Tinian, during June and July 1944), American forces were getting close to Japan itself. From the Marianas, the very long-range B-29 Superfortress heavy bombers of the U.S. Army Air Forces (USAAF) could bomb the Japanese home islands from well-supplied air bases – ones with direct access to supplies via cargo ships and tankers. (The earlier B-29 bombing campaign against Japan had been from the end of a very long and tortuous supply line via British India and British Burma – one that proved to be woefully inadequate. All B-29s were transferred to the Marianas during the fall of 1944.)
There had been a close relationship between the people of the Philippines and the United States since 1898, with the Philippines becoming the Commonwealth of the Philippines in 1935, and promised their independence in mid-1946. Furthermore, an extensive series of air attacks by the American Fast Carrier Task Force under Admiral William F. Halsey against Japanese airfields and other bases on the Philippines had drawn little Japanese opposition, such as interceptions by Japanese Army fighter planes. Upon Admiral Halsey's recommendation, the Combined Chiefs of Staff, meeting in Canada, approved a decision to not only move up the date for the first landing in the Philippines, but also to move it north from the southernmost island of Mindanao to the central island of Leyte, Philippines. The new date set for the landing on Leyte, October 20, 1944, was two months before the previous target date to land on Mindanao.
The Filipino people were ready and waiting for the invasion. After General MacArthur had been evacuated from the Philippines in March 1942, all of its islands fell to the Japanese. The Japanese occupation was harsh, accompanied by atrocities and with large numbers of Filipinos pressed into slave labor. From mid-1942 through mid-1944, MacArthur and Nimitz supplied and encouraged the Filipino guerrilla resistance by U.S. Navy submarines and a few parachute drops, so that the guerrillas could harass the Japanese Army and take control of the rural jungle and mountainous areas – amounting to about half of the archipelago. While remaining loyal to the United States, many Filipinos hoped and believed that liberation from the Japanese would bring them freedom and their already-promised independence.
The Australian government offered General MacArthur the use of the First Corps of the Australian Army for the Liberation of the Philippines. MacArthur suggested that two Australian infantry divisions be employed, each of them attached to a different U.S. Army Corps, but this idea was not acceptable to the Australian Cabinet, which wanted to have significant operational control within a certain area of the Philippines, rather than simply being part of a U.S. Army Corps. No agreement was ever reached between the Australian Cabinet and MacArthur – who might have wanted it that way. As a result, the Australian Army played virtually no part in the Philippines. However, units from the Royal Australian Air Force and the Royal Australian Navy, such as the heavy cruiser HMAS Australia, were involved.
During the American re-conquest of the Philippines, the guerrillas began to strike openly against Japanese forces, carried out reconnaissance activities ahead of the advancing regular troops, and took their places in battle beside the advancing American divisions.
On October 20, 1944, the U.S. Sixth Army, supported by naval and air bombardment, landed on the favorable eastern shore of Leyte, one of the islands of the Visayas island group, northeast of Mindanao. The Japanese miscalculated the relative strength of the naval and air forces, and they attempted to destroy the landing. This brought about the massive sequence of battles called the Battle of Leyte Gulf, fought on October 23 through October 26. This decisive victory by the U.S. Navy, its Fast Carrier Task Force, its surface fleet, and its submarines effectively destroyed the remainder of the Imperial Japanese Navy (IJN), which had already lost all of its effective aircraft carrier forces. The IJN had four of its carriers sunk (ships with depleted air squadrons – which were used only as decoys), numerous battleships and heavy cruisers, and a large number of light cruisers and destroyers. The IJN was never able to fight a major battle after this.
The U.S. Sixth Army continued its advance from the east, as the Japanese rushed reinforcements to the Ormoc Bay area on the western side of the island. While the Sixth Army was continually reinforced, the U.S. Fifth Air Force and the U.S. 3rd Fleet's Task Force 38 were able to devastate the Japanese attempts at air attacks and at landing new reinforcements and supplies, and also provide much support to the Army's ground troops during what is known as the Battle of Ormoc Bay from November 11 to December 21, 1944.
The Filipino guerrillas also performed valuable service in maintaining public order and in keeping the roads and highways free of congestion. After the American beachheads were established, the Leyte guerrilla groups were attached directly to the Sixth Army corps and divisions to assist in scouting, intelligence, and combat operations. With the initial U.S. Sixth Army landings on the beaches at Tacloban and Dulag, Colonel Ruperto Kangleon's units went into action. They dynamited key bridges to block Japanese displacement toward the target area; they harassed enemy patrols; and they sabotaged supply and ammunition depots. Information on enemy troop movements and dispositions sent from guerrilla outposts to Kangleon's Headquarters was dispatched immediately to Sixth Army.
During many torrential rains and over difficult terrain, the advance continued across Leyte and onto the major island of Samar, just north of Leyte. On December 7, 1944, the U.S. Army units made another amphibious landing at Ormoc Bay and, after a major land and air battle, the landing force cut off all Japanese ability to reinforce and resupply their troops on Leyte. Although fierce fighting continued on Leyte for months, the U.S. Army was always in control.
The U.S. 6th Army's second major target to attack was Mindoro. This large island is directly south of Luzon and Manila Bay, and MacArthur's main goal in taking it was to be able to construct airfields on it for fighter planes that could dominate the sky over the most-important island of Luzon, with its major seaport and capital city of Manila.
The Seventh Fleet's large invasion convoy from Leyte to Mindoro came under strong attack by kamikazes, but they could not delay the American invasion of Mindoro. Mindoro was only lightly occupied by the Japanese Army, and much of it was held by Filipino guerrillas, so Mindoro was quickly overrun. U.S. Army engineers set about rapidly constructing a major air base at San Fabian. Besides being close to Luzon, Mindoro has another advantage: good flying weather nearly all the time, because this is a part of the Philippines that is relatively dry – quite unlike Leyte which receives torrential rains most of the year, not only giving it poor flying weather, but making it very muddy and difficult to construct airfields.
San Fabian was also the location of another breakthrough: the first appearance during the War in the Pacific of USAAF squadrons flying the fast, long-range P-51B Mustang fighters – far superior to anything that the Imperial Japanese Army or Navy had.
Mindoro was a major victory for the 6th Army and the USAAF, and it also provided the major base for the next move of MacArthur's 6th Army: the invasion of Luzon, especially at Lingayen Gulf on its western coast.
On December 15, 1944, landings against minimal resistance were made on the southern beaches of the island of Mindoro, a key location in the planned Lingayen Gulf operations, in support of major landings scheduled on Luzon. On January 9, 1945, on the south shore of Lingayen Gulf on the western coast of Luzon, General Krueger's Sixth Army landed his first units. Almost 175,000 men followed across the twenty-mile (32 km) beachhead within a few days. With heavy air support, Army units pushed inland, taking Clark Field, 40 miles (64 km) northwest of Manila, in the last week of January.
Two more major landings followed, one to cut off the Bataan Peninsula, and another, which included a parachute drop, south of Manila. Pincers closed on the city. On February 3, 1945, elements of the U.S. 1st Cavalry Division pushed into the northern outskirts of Manila, and the 8th Cavalry Regiment (organized as infantry) passed through the northern suburbs and into the city itself.
As the advance on Manila continued from the north and the south, the Bataan Peninsula was rapidly secured. On February 16, paratroopers and amphibious units simultaneously assaulted the islet of Corregidor. Taking this stronghold was necessary because troops there could block the entrance of Manila Bay. The Americans needed to establish a major harbor base at Manila Bay to support the expected invasion of Japan, planned to begin on November 1, 1945. Resistance on Corregidor ended on February 27, and then all resistance by the Japanese Empire ceased on August 15, 1945, obviating the need for an invasion of the Japanese Home Islands.
Despite initial optimism, fighting in Manila was harsh. It took until March 3 to clear the city of all Japanese troops, and the Japanese Marines, who fought on stubbornly and refused to either surrender or to evacuate as the Japanese Army had done. Fort Drum, a fortified island in Manila Bay near Corregidor, held out until April 13, when a team of Army troops went ashore and pumped 3,000 gallons of diesel fuel into the fort, then set off incendiary charges. No Japanese soldiers in Fort Drum survived the blast and fire.
In all, ten U.S. divisions and five independent regiments battled on Luzon, making it the largest American campaign of the Pacific war, involving more troops than the United States had used in North Africa, Italy, or southern France.
Palawan Island, between Borneo and Mindoro, the fifth largest and western-most island of the Philippines, was invaded on February 28, with landings of the Eighth United States Army at Puerto Princesa. The Japanese put up little direct defense of Palawan, but cleaning up pockets of Japanese resistance lasted until late April, with the Japanese using their common tactic of withdrawing into the mountains and jungles, dispersed as small units. Throughout the Philippines, U.S. forces were aided by Filipino guerrillas to find and dispatch the holdouts, the last of whom, Hiroo Onoda, did not surrender until 1974, in the mountains of Lubang Island in Mindoro.
The U.S. Eighth Army then moved on to its first landing on Mindanao (April 17), the last of the major islands of the Philippines to be taken. Mindanao was followed by invasion and occupation of Panay, Cebu, Negros and several islands in the Sulu Archipelago. These islands provided bases for the U.S. Fifth and Thirteenth Air Forces to attack targets throughout the Philippines and the South China Sea.
Following additional landings on Mindanao, U.S. Eighth Army troops continued their steady advance against stubborn resistance. By the end of June, the enemy pockets were compressed into isolated pockets on Mindanao and Luzon where fighting continued until the Japanese surrender on August 15, 1945. However, some units of the Japanese Army were out of radio contact with Tokyo, and it was difficult to convince some of them that Japan had surrendered. As at many Pacific Islands, major Japanese officials, including members of the Imperial Family, visited in person to convince the soldiers that they must surrender by order of the Emperor.
|Central and Southern Philippines||2,070||6,990||9,060|
|Central and Southern Philippines||50,260||2,695||52,955|
The radio also stated that members of the Imperial family were being sent to Japan's numerous theaters of operations as personal representatives of the Emperor to expedite and insure full compliance with the Imperial order to cease hostilities.
The 460th Fighter-Interceptor Training Squadron is an inactive United States Air Force unit. Its last assignment was with Tactical Air Command's 325th Fighter Weapons Wing at Tyndall Air Force Base, Florida, where it was inactivated on 15 October 1982.801st Medical Air Evacuation Squadron
The 801st Medical Air Evacuation Squadron was a United States Army Air Forces (USAAF) unit that provided aeromedical evacuation and support services to front-line units in the Pacific Theater of World War II. From the latter part of the Guadalcanal Campaign through Operation Cartwheel it was attached to Marine Aircraft Group 25 and the South Pacific Combat Air Transport Command (SCAT).913th Air Refueling Squadron
The first predecessor of the squadron was organized in 1940 as the 13th Transport Squadron. During World War II, as the 13th Troop Carrier Squadron, the squadron served in the South West Pacific Theater of World War II, earning two Distinguished Unit Citations, a Navy Unit Commendation and a Philippine Republic Presidential Unit Citation for its wartime actions. Its last assignment was with the 403d Troop Carrier Group at Nichols Field, Luzon, Philippines, where it was inactivated on 15 October 1946.
The 913th Air Refueling Squadron was activated by the United States Air Force in 1958 at Barksdale Air Force Base, Louisiana, where it was last assigned to the 2d Bombardment Wing. The squadron responded to the Cuban Missile Crisis and provided Boeing KC-135 Stratotanker aircraft and aircrews to support the Viet Nam War. It was inactivated on 1 November 1981 and replaced by a squadron flying McDonnell Douglas KC-10 Extenders.
The two squadrons were consolidated in September 1985 but the consolidated squadron has not been active since.Alamo Scouts
The Alamo Scouts (U.S. 6th Army Special Reconnaissance Unit) was a reconnaissance unit of the Sixth United States Army in the Pacific Theater of Operations during World War II. The unit is best known for its role in liberating American prisoners of war (POWs) from the Japanese Cabanatuan POW camp near Cabanatuan, Nueva Ecija, Philippines in January 1945.Basilio J. Valdes
Basilio J. Valdes (10 July 1892 – 26 January 1970) was a Filipino Doctor, General and Minister. Valdes was Chief of Staff of the Philippine Armed Forces from 1939 and in 1941 he was appointed Secretary of National Defense by President Manuel L. Quezon. After the Japanese invasion of the Philippines at the beginning of the Second World War, he was one of the members of Quezon's war cabinet in exile.Colonel Jesus Villamor Air Base
Colonel Jesus Villamor Air Base, or simply Villamor Air Base (IATA: MNL, ICAO: RPLL), named for Filipino WWII pilot Jesús A. Villamor is the home of the Philippine Air Force (PAF) and shares runways with the Ninoy Aquino International Airport (NAIA). It is also known as Nichols Field or Nichols Air Base possible known as Nichols Freeport Zone. Chiefly used as a PAF transport/helicopter airbase, it is also the military installation that the Philippine president uses when departing for foreign or domestic trips, though foreign departures are mostly done at the Philippine Airlines-operated NAIA Terminal 2 (as PAL is the official charter airline for the Philippine president). Also, foreign dignitaries visiting Manila would usually arrive at the air base.Cyrus Vance
Cyrus Roberts Vance (March 27, 1917 – January 12, 2002) was an American lawyer and United States Secretary of State under President Jimmy Carter from 1977 to 1980. Prior to that position he was the Secretary of the Army and the Deputy Secretary of Defense.
As Secretary of State, Vance approached foreign policy with an emphasis on negotiation over conflict and a special interest in arms reduction. In April 1980, Vance resigned in protest of Operation Eagle Claw, the secret mission to rescue American hostages in Iran. He was succeeded by Edmund Muskie.
Vance was the cousin (and adoptive son) of 1924 Democratic presidential nominee and lawyer John W. Davis. He was the father of Manhattan District Attorney Cyrus Vance Jr.Fort Drum (Philippines)
Fort Drum (originally known as El Fraile Island), also known as "the concrete battleship", is a heavily fortified island situated at the mouth of Manila Bay in the Philippines, due south of Corregidor Island. The reinforced concrete sea fort shaped like a battleship was built by the United States in 1909 as one of the harbor defenses at the wider South Channel entrance to the bay during the American colonial period. It was unique among forts built by the United States between the Civil War and early World War II, both as a sea fort and in having turrets. It was captured and occupied by the Japanese during World War II, and was recaptured by the U.S. after igniting petroleum and gasoline in the fort, leaving it permanently out of commission. 68 Japanese soldiers perished in the blaze. It took the U.S. soldiers days before they could even go into the fortress because of the heat.
The now-abandoned fort was named after Brigadier General Richard C. Drum, who served with distinction during the Mexican–American War and the American Civil War, and died on October 15, 1909, the year of the fort's construction. The island and the other former harbor defenses of Manila Bay fall under the jurisdiction of the City of Cavite in Cavite Province.Fort Hughes
Fort Hughes (Caballo Island, the Philippines) was part of the Harbor Defenses of Manila and Subic Bays built by the Philippine Department of the U.S. Army in the early 1900s. The fort was named for Major General Robert P. Hughes, a veteran of the American Civil War, Spanish–American War, and the Philippine–American War.Fort Wint
Fort Wint (known as Grande Island, the Philippines) was part of the harbor defenses of Manila and Subic Bays built by the Philippine Department of the United States Army between 1907 and 1920 in response to recommendations of the Taft Board prior to the non-fortification clause of the Washington Naval Treaty. Fort Wint was located on Grande Island at the entrance of Subic Bay, approximately 35 miles (56 km) north of Manila Bay. The fort was named for Brigadier General Theodore J. Wint. As specified in the National Defense Act of 1935, this was one of the locations where coastal artillery training was conducted. A battery of the 60th Coast Artillery (AA) was stationed here. Now owned by Jimmy and Jocelyn McCormick.Fortunato Abat
Fortunato Abat (June 10, 1925 – March 7, 2018) was a Filipino major general who served as the 20th Secretary of the Department of National Defense (DND), Ambassador to the People's Republic of China, and Commanding General of the Philippine Army.Hiroo Onoda
Hirō "Hiroo" Onoda (小野田 寛郎, Onoda Hirō, 19 March 1922 – 16 January 2014) was an Imperial Japanese Army intelligence officer who fought in World War II and was a Japanese holdout who did not surrender at war's end in August 1945. After the war ended Onoda spent 29 years holding out in the Philippines until his former commander traveled from Japan to formally relieve him from duty by order of the Emperor in 1974. He held the rank of second lieutenant in the Imperial Japanese Army. He was the penultimate Japanese soldier to surrender, with Teruo Nakamura surrendering later in 1974.Juan Pajota
Captain Juan Pajota (c.1914 – 1976) was involved in the Raid at Cabanatuan, an action which took place in the Philippines on 30 January 1945 by US Army Rangers and Filipino guerrillas and resulted in the liberation of more than 500 American prisoners of war (POWs) from a Japanese POW camp near Cabanatuan.Marine Aircraft Group 25
Marine Air Group (MAG) 25 was a United States Marine Corps combat air transport group that provided logistical support, including cargo and personnel transport and aeromedical evacuation, to forward units during World War II and the Korean War. During World War II it formed the nucleus of the South Pacific Combat Air Transport Command.Operation Musketeer
