along the Orion-Bagac Line, making them as the key unit to hold any southern movement of the Japanese forces through Trail 29. The 41st Division gave the stiffest opposition to the Japanese offensive, punishing elements of the opposing Japanese 65th Brigade's 141st Battalion. BGen. Lim at some point directed small and effective counter-offensives, only to be directed to return to the Bagac-Orion Line. The 141st Battalion by April 9 recorded that they have lost 70% of their manpower facing the 41st Division units. In exacting revenge after the Fall of Bataan, the 65th Brigade mistook the men of the 91st Division for the 41st Division, and had them summarily executed to now what is known as the Pantingan River massacre. The division held the extreme left of the II Corps line on the eve of the last Japanese offensive in Bataan on April 3, along with the 31st Division. Such was the effect of bombardment that even before the Japanese tank-infantry attack had begun to roll, the 41st Division had ceased to exist as an effective military organization. The units most affected by the bombardment and the assault were the 42d and 43d Infantry. The first, in the center of the division front where bamboo fires burned fiercely, had retreated in a disorderly fashion, some of the men following Trail 29 into the 41st Infantry area, and others drifting eastward to join the retreating 43d on the western slopes of Mt. Samat. Only the 41st Infantry on the extreme left of the line, which had escaped the full weight of the preliminary bombardment, had withdrawn in an orderly fashion. Despite the attempt to stem the Japanese advance, by 4 April the division was routed. On 9 April, the inevitable bitter end came. MGen. Edward P. King Jr., commander of Bataan Defense Force, surrendered to prevent the unnecessary slaughter of his war-torn troops, negotiating the surrender of the Bataan troops with the Japanese High Command. BGen. Vicente Lim and his division staff surrendered following MGen. Edward King's capitulation of Bataan. The division initially began marching from Pilar, Bataan on what would later be known as the infamous Bataan Death March all the way to San Fernando, Pampanga. They covered about 65 km under intense conditions of heat and brutality from the guards. Upon arrival in San Fernando 6,000 of them were herded in the city's cock pit arena. The following day,
