Location
Mindanao Island is the southernmost major island and second largest island in the Philippines. Also known simply as Mindanao. Borders the Mindanao Sea (Bohol Sea) to the north.

Wartime History
On April 29, 1942 a Japanese invasion force arrived in Cotabato Bay and landed Japanese Army forces. By May 9, 1942 the Japanese captured Mindanao with the last U.S. forces surrendered three days later. Meanwhile, U.S. Army Col. Wendell W. Fertig escaped Japanese captivity and organized a guerrilla movement on Mindanao that was highly effective and had over 35,000 men at its height and were supplied by U.S. submarines. Their efforts restricted the occupying Japanese to the major cities and towns.

The Japanese anticipated an American landing on Mindanao and amassed many forces to defend the area.  Initially, the U.S. Army planned for Mindanao to be the first island liberated with an amphibious landing at Cotabato Bay scheduled for December 20, 1944 but after the capture of the "Koga Papers" aboard crashed H8K2 Emily that outlined Plan "Sho" or Plan "Z" and revealed Leyte was lightly defended and the invasion plans were changed. Instead, Mindanao became the last major island liberated during the Philippines campaign 1944–1945.

By April 1945, most of the troops had been withdrawn to fight elsewhere leaving only the Japanese 35th Army commanded by General Suzuki to defend the eastern part of the island, and holdout indefinitely with 43,000 troops. His troops were short on supplies and low on moral and faced ongoing guerrilla resistance. After General Suzuki was killed by an air attack while traveling by boat from Cebu back to Mindanao. Afterwards, replaced by Lt. General Gyosaku Morozumi.
