[5] In the summer of 1942, Harris and two others left Whitcomb and attempted to sail to China in a motorboat, but the engine failed and the boat drifted for 29 days with little food or water.

[6] Harris headed towards Australia hoping to rejoin American forces he heard were fighting in Guadalcanal, but he was recaptured in June[7] or September 1943[8] by Japan on Morotai island, Indonesia, around 1,000 miles (1,600 km) from Bataan.

Harris experienced malnutrition and brutal treatment at the hands of his jailers, notably by Sueharu Kitamura (later convicted of war crimes).

[13][14] According to fellow captive, Pappy Boyington, Harris was knocked down 20 times with a baseball bat for reading a newspaper stolen from the trash.

Directing his Battalion in affording flank protection for the regimental vehicle train and the first echelon of the division trains proceeding from Hagaru-ri to Koto-ri, Lieutenant Colonel Harris, despite numerous casualties suffered in the bitterly fought advance, promptly went into action when a vastly outnumbering, deeply entrenched hostile force suddenly attacked at point-blank range from commanding ground during the hours of darkness.

With his column disposed on open, frozen terrain and in danger of being cut off from the convoy as the enemy laid down enfilade fire from a strong roadblock, he organized a group of men and personally led them in a bold attack to neutralize the position with heavy losses to the enemy, thereby enabling the convoy to move through the blockade.

Consistently exposing himself to devastating hostile grenade, rifle and automatic weapons fire throughout repeated determined attempts by the enemy to break through, Lieutenant Colonel Harris fought gallantly with his men, offering words of encouragement and directing their heroic efforts in driving off the fanatic attackers.
