Question: Which lasted longer, Korean War or Battle of Mindanao? 

full_context: Document 1: Battle of Luzon: The Battle of Luzon, fought 9 January – 15 August 1945, was a land battle of the Pacific Theater of Operations of World War II by the Allied forces of the U.S., its colony the Philippines, and allies against forces of the Empire of Japan. The battle resulted in a U.S. and Filipino victory. The Allies had taken control of all strategically and economically important locations of Luzon by March 1945, although pockets of Japanese resistance held out in the mountains until the unconditional surrender of Japan. While not the highest in U.S. casualties, it is the highest net casualty battle U.S. forces fought in World War II, with 192,000 to 205,000 Japanese combatants dead (mostly from starvation and disease), 10,000 American combatants killed, and between 120,000 to 140,000 Filipino civilians and combatants killed.
Document 2: Borneo campaign (1945): The Borneo Campaign of 1945 was the last major Allied campaign in the South West Pacific Area during World War II. In a series of amphibious assaults between 1 May and 21 July, the Australian I Corps, under Lieutenant General Leslie Morshead, attacked Imperial Japanese forces occupying the island. Allied naval and air forces, centred on the U.S. 7th Fleet under Admiral Thomas Kinkaid, the Australian First Tactical Air Force and the U.S. Thirteenth Air Force also played important roles in the campaign. They were resisted by Imperial Japanese Navy and Army forces in southern and eastern Borneo, under Vice-Admiral Michiaki Kamada, and in the north west by the Thirty-Seventh Army, led by Lieutenant-General Baba Masao.
Document 3: United States in the Korean War: At the conclusion of World War II the Allied nations began the process of disarmament of Axis controlled regions. Japan occupied Korea at this time and had been in control since 1910. In 1945, the decision was made to have American Marines forces oversee Japanese surrender and disarmament south of the 38th parallel and the Soviet Union would facilitate the change of power to the north. At the time there was no political motivation and seemed to be a logical and convenient plan of action. The original agreement and intent was to create a unified and independent Korea out of the post Japanese occupation era. Instead each side of the 38th parallel established its own government under the influence of the occupational country; the United States in South Korea and the Soviet Union in North Korea. Both new Korean governments discredited the other and claimed to be the only legitimate political system. Tensions between the North and South escalated and each side began to petition foreign powers for resources and support. South Korea wanted weapons and supplies from Truman and the United States government while North Korea sought help from Stalin and the Soviet Union. The United States was still war weary from the disruptive World War II campaign and refused South Korea's request for weapons and troops. North Korea convinced the Soviet Union to supply them with the weapons and support they requested. This decision coincided with the United States withdrawing the last remaining combat troops from South Korea. North Korea saw its opportunity and attacked South Korean forces at the 38th parallel on June 25, 1950 and thus initiating the Korean War.
Document 4: Battle of Mindanao: The Battle of Mindanao was fought by United States forces and allied Filipino guerrillas against the Japanese from 10 March - 15 August 1945 on the island of Mindanao in the Philippines in a series of actions officially designated as Operation VICTOR V. It was part of the campaign to liberate the Philippines during World War II. The battle was waged to complete the recapture of the southernmost portions of the archipelago.
Document 5: Korean War: The Korean War (in South Korean Hangul: 한국전쟁 ; Hanja: 韓國戰爭 ; RR: "Hanguk Jeonjaeng " , "Korean War"; in North Korean Chosŏn'gŭl: 조국해방전쟁 ; Hancha: 祖國解放戰爭 ; MR: "Choguk haebang chǒnjaeng " , "Fatherland Liberation War"; 25 June 1950 – 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
Document 6: Second Phase Campaign: The Second Phase Campaign of the Korean War was an extended military offensive by the Chinese People's Volunteer Army during the last week of November, 1950, and the first two weeks of December. The two major engagements were battles near the Ch'ongch'on River in the Chinese-designated Western Sector and Chosin Reservoir in their Eastern Sector. The Chinese opposed United Nations-authorized forces composed of American military and various allied forces.
Document 7: Korean War POWs detained in North Korea: Tens of thousands of South Korean soldiers were captured by the North Korean and Chinese forces during the Korean War (1950–53) but were not returned during the prisoner exchanges under the 1953 . Most are presumed dead, but the South Korean government estimates some 560 South Korean prisoners of war still survive in North Korea. The issue of unaccounted South Korean POWs from the Korean War has been in dispute since the Armistice in 1953. North Korea continues to deny it holds these South Korean POWs. Interest in this issue has been renewed since 1994, when Lt. Cho Chang-ho, a former South Korean soldier presumed to have been killed in the war, escaped from North Korea. As of 2008, 79 former South Korean soldiers have escaped from North Korea.
Document 8: Battle of Bataan (1945): The Battle for the Recapture of Bataan from 31 January to 21 February 1945, by US forces and Allied Filipino guerrillas from the Japanese, part of the campaign for the liberation of the Philippines, was waged to secure the western shore of Manila Bay to enable the use of its harbor and open new supply lines for American troops engaged in the crucial battle for the liberation of Manila.
Document 9: Battle of the Visayas: The Battle of the Visayas was fought by U.S. forces and Filipino guerrillas against the Japanese from 18 March – 30 July 1945, in a series of actions officially designated as Operations Victor I and II, and part of the campaign for the liberation of the Philippines during World War II. The battle was waged to complete the recapture of the central portions south of the archipelago and secure them from remaining Japanese forces.
Document 10: Battle of Davao: The Battle of Davao was fought by Allied forces during World War II. It contained American and Philippine Commonwealth troops including locally organized guerrillas against the Japanese from May 3 to 18, 1945 at the city of Davao and its vicinity in the island of Mindanao in the Philippine Archipelago. It is part of Operation VICTOR V, an offensive operation against Japanese forces in Mindanao, and part of the campaign for the liberation of the Philippines during World War II. The battle was the decisive engagement of the Mindanao Campaign.
Document 11: South Korea–United States relations: Republic of Korea–United States relations (Hangul: 한미 관계 ; Hanja: 韓美 關係 ; RR: "Hanmi gwangye "; MR: "Hanmi kwan'gye " ) have been extensive since 1950, when the United States helped establish the modern state of South Korea, also known as the Republic of Korea, and fought on its UN-sponsored side in the Korean War (1950–1953). During the subsequent four decades, South Korea experienced tremendous economic, political and military growth, and significantly reduced U.S. dependency. From Roh Tae-woo's administration to Roh Moo-hyun's administration, South Korea sought to establish an American partnership, which has made the Seoul–Washington relationship subject to some strains, especially with the Anti-US/Korean sentiments. However, relations between the United States and South Korea have greatly strengthened under the conservative, pro-U.S. Lee Myung-bak administration. At the 2009 G-20 London Summit, U.S. President Barack Obama called South Korea "one of America's closest allies and greatest friends." In addition, South Korea has been designated as a Major non-NATO ally.
Document 12: Battle of Leyte: The Battle of Leyte in the Pacific campaign of World War II was the amphibious invasion of the Gulf of Leyte in the Philippines by American forces and Filipino guerrillas under the command of General Douglas MacArthur, who fought against the Imperial Japanese Army in the Philippines led by General Tomoyuki Yamashita from 17 October - 26 December 1944. The operation code named "King Two" 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.
Document 13: Foreign relations of North Korea: The foreign relations of North Korea – officially the Democratic People's Republic of Korea (DPRK) – have been shaped by its conflict with capitalist countries like South Korea and its historical ties with world communism. Both the government of the DPRK and the government of South Korea (officially the Republic of Korea) claim to be the government of the whole of Korea. The Korean War in the 1950s failed to resolve the issue, leaving the DPRK locked in a military confrontation with South Korea and the United States Forces Korea across the Demilitarized Zone. At the start of the Cold War, the DPRK only had diplomatic recognition by Communist countries. Over the following decades, it established relations with developing countries and joined the Non-Aligned Movement. When the Eastern Bloc collapsed in the years 1989–1991, the DPRK made efforts to improve its diplomatic relations with developed capitalist countries. At the same time there were international efforts to resolve the confrontation on the Korean peninsula, especially when the North acquired nuclear weapons after the demise of the Soviet Union, its main economic backer.
Document 14: Battle of Baguio (1945): The Battle of Baguio occurred between 21 February and 26 April 1945, and was part of the greater Luzon campaign during the Allied liberation of the Philippines at the end of World War II. During the battle, American and Philippine forces recaptured the city of Baguio on the island of Luzon from a Japanese occupation force. One of the last tank engagements of the Philippine campaign took place during the battle. Baguio later became the scene of the final surrender of Japanese forces in the Philippines in September 1945.
