known as KP duty. He noticed that one of his unit's 75 mm M1917 field gun had been silenced, and its crew killed. Without orders, he ran the across the shell-swept area to the inactive gun position. Once there, he organized a squad of volunteers who returned Japanese artillery fire. The position remained under constant and heavy fire for the rest of the afternoon. While Calugas and his squad maintained a steady fire on the enemy positions, other soldiers had time to dig in and defend the line. As the day ended and combat subsided, he returned to KP. For his actions on that day, his superiors recommended Calugas for the United States military's highest decoration for valor, the Medal of Honor. Before he could receive it, however, all American forces on Bataan surrendered to Japanese forces. Surrender of Bataan and the death march Arguably, the Battle of Bataan represented the most intense phase of Imperial Japan's invasion of the Philippines during World War II. During the final stage of the Battle of Bataan and after repeated assaults and artillery fire by Japanese forces, the communications and defenses of the allies on Bataan peninsula had been almost completely destroyed. On the last two days, the entire Allied defense collapsed, clogging all roads with refugees and fleeing troops. By April 8, the senior U.S. commander on Bataan, Major General Edward "Ned" P. King, Jr., recognized the futility of further resistance, and explored proposals for capitulation.

After the surrender, Calugas and the other prisoners marched from Mariveles to Camp O'Donnell, a prison camp in the province of Tarlac. The Japanese, having expected the fighting to continue, anticipated about 25,000 prisoners of war and were inadequately prepared or unwilling to transport a group of prisoners three times the size. The majority of the prisoners of war were immediately relieved of their belongings and endured a 61-mile (98 km) march in deep dust, over vehicle-broken macadam roads, and crammed into rail cars for the portion of the journey from San Fernando to Capas. En route, over 21,000 men and women died from disease, starvation, dehydration, heat prostration, untreated wounds, and wanton execution. The deaths of Filipinos
