Along with 2/82nd Infantry under 1Lieutenant Luis Jakosalem who came from Cebu, Davao PC Battalion under Major Gregorio Ferreols, and some volunteers that his force reached more than 2,000. Despite the large force, Colonel Hilsman don't have field artillery guns, coastal guns, and antiaircraft artillery pieces. Lack of training due to due limited supply of ammunition prevented soldiers to fire their rifles. To beefed up the leaderships Hilsman had Major Frank McGee who is retired Army officer turned planter in Malalag area, he also put Major Alvin T. Wilson in command of 2nd Battalion 82nd Infantry. On December 20, 1941 Muira and Sakaguchi detachments landed respectively in Tibungco in the northern part and Talomo in the southern part of the city. In less a day Colonel Hilsman's troops were routed and forced to retreat via Davao-Tigatto road. They undertook 15 days hiking through the thick jungle trek and deep ravine eating corn, monkey meat, and bananas.

He also ordered Frissell to look for the missing unit and Hilsman, word reached him from moros and soldiers from the unit that straggled in Davao area that Hilsman has gone to Bukidnon via the Callawa. Upon knowing Japanese has made another landing in Malalag, Frissell posted 1st Battalion 101st Infantry at west of Digos towards Malalag and 2nd Battalion 101st Field Artillery to the north towards Davao City. From January to February 1942, Frissell attacked Japanese who landed in Malalag and their supply warehouses in Padada. A detachment of 2.95inch Mountain Guns under Captain Manuel Acosta was sent from Malaybalay to provide fire support. This small detachment made a moral booster to the Filipino – American defenders. Japanese naval fire and air support prevented Frissell troops in attacking Japanese in Padada and Malalag. In the engagement it destroyed 2 of the artillery battery guns and killed Captain Acosta. The unit and guns were withdrawn back to Malaybalay as ordered by the Force commander.

He sent commando unit 101st Reconnaissance Battalion under Captain Narciso Del Rosario raided Japanese warehouses in Padada, resulting to destroying supplies and burning the warehouses.
