They were opposed by defending forces consisting of 2/101st Infantry, 2/82nd Infantry, a battery of 75mm mountain guns from 101st Field Artillery of the 101st Division of the Philippine Army, and few Philippine constabularies under overall command of sector commander Lieutenant Colonel Roger Hilsman after few skirmishes they were overran and dispersed due to lack of coordination and fire power. Sakaguchi Detachment composed of 146th Infantry Regiment with one artillery and tank battalions under the command of Major General Sakaguchi Shizuo landed the following week to reinforced the Muira Detachment composed of 1/33rd Infantry under Lieutenant Colonel Muira Toshio. When Japanese gained a strong foothold, Sakaguchi Detachment left and landed in Sulu Island in preparation for Japanese invasion of Borneo where much needed oil are found, leaving Muira detachment in Davao area.

Split of command

On February 6, 1942, General MacArthur decided to take control of Mindoro and Panay Islands which are nearer to Luzon Island to manage the supply route and delivery of supplies. This made him decide that Visayas Islands should be separated from General Sharp's command. This took effect on the General MacArthur's departure to Australia on March 17, 1942.

Justice Secretary Jose Abad Santos was captured by the Japanese in Cebu who was making its way to reach Mindanao.

Main article: Mindanao Force

General Sharp activated 102nd Division to cover the defense of Northern Mindanao from units coming from Visayas Islands and provincial battalions. He selected Colonel William P. Morse as commander above the Taguloan river. Kawamura Detachment invaded Mindanao thru Northern Mindanao and Kawaguchi Detachment landed Cotabato and Malabang, Lanao. They were met by Filipino-American forces with fierce fighting but in the end the superior weaponry won and lack of artilleries guns and air support made the defenders easily dispersed from their position. General Sharp forces was still fighting and acknowledge he could not hold on much longer and communicated to General MacArthur's headquarters in Australia,

Reestablishment

Following the fall of Bataan in April 9, Corregidor islands was the focus of Japanese intense operations until May 6. General Wainwright still communicated directly to General Sharp for Visayas and Mindanao forces despite General Chynoweth being equal to General Sharp due to separation of commands. On April 19, 1942 with the subjugation of the island of Cebu by the Japanese, the Visayan Force of General Chynoweth could no longer function as a force due to lost of Cantabaco town where Visayan Force HQ located, it lost communication with other gartison in the Visayas. Wainwright ordered Sharp to reestablished the Visayas-Mindanao Force to take command of the remaining garrison of the Visayas islands. Before General Wainwright moved forward to seek terms of surrender to General Homma Masaharu commander of the 14th Army he released General Sharp from his command and ordered to report directly to General MacArthur. But later insisted no less the surrender of entire Filipino-American forces in the Philippines before he accepts the surrender. General Sharp was forced to abide the order of General Wainwright due to the pressure that forces in the Corregidor are held hostage and will be massacred should he not surrender his forces. He sent emissary Lieutenant Colonel Jessie Traywick to personally deliver his hand written order and ensure this order are carried by General Sharp. In turn Sharp sent emissaries to General Chynoweth commander of Visayan Force and to other commanders in major islands in the Visayas.
