Mindanao Force is a corps size military unit defending the island of Mindanao the second largest Island of the Philippines from March 17, 1942, to its surrender on May 9, 1942. The force was already created when the Visayas-Mindanao Force was split into two in March 1942. It was initiated in February 1942 in the headquarters of US Army Forces in the Far East but took effect when General Douglas MacArthur departed for Australia on March 17, 1942.^[1]

Visayas-Mindanao Force (VMF) commander Major General William F. Sharp assumed command of the force since he moved his previous headquarters in January in that year. He retained his staffs from his previous VMF HQ to his Mindanao Force HQ and released Visayan Force to Brigadier General Bradford Chynoweth. Along with Luzon Force and Harbor Defense of Manila and Subic, both headquarters are to report directly to US Forces in the Philippines HQ in Corregidor under Lieutenant General Jonathan Wainwright IV.

Main mission of Mindanao Force is to protect Del Monte Field and construct more air fields around Mindanao so supplies from Australia can be flown in preparation for the relief of the Philippine Garrison by General MacArthur. This was not materialized due to the grip of the Japanese forces in the Philippines and its surrender on May 10, 1942.

Fort and ordered to relocate in Mindanao the following units, 73rd Infantry Regiment from Negros, 61st Infantry, 62nd Infantry, and 61st Field Artillery from Panay.^[2] He also had forces from Leyte which composed by 81st Infantry Regiment and 93rd Infantry Regiment that wasn't included during the transfer of 91st Division to Luzon.
