On April 3, the entire Orion-Bagac Line was subjected to incessant bombings by 100 aircraft and artillery bombardment by 300 artillery pieces from 9:00 a.m. to 3:00 pm, which turned the Mount Samat stronghold into an inferno. Over the course of the next three days (Good Friday to Easter Sunday, 1942), the Japanese 65th Brigade and 4th Division spearheaded the main attack at the left flank of II Corps. Everywhere along the line, the American and Filipino defenders were driven back by Japanese tanks and infantry. The next morning, April 9, 1942, General King met with Major General Kameichiro Nagano and, after several hours of negotiations, the remaining weary, starving and emaciated American and Filipino defenders on the battle-swept Bataan Peninsula surrendered. https://en.wikipedia.org/wiki/Battle_of_Ba...
