[9] Battery Fuger was named for Lt. Col. Frederick Füger, a Civil War Medal of Honor recipient.

The fort's garrison executed destruction procedures on their guns prior to their surrender and the Japanese occupation.

[1] American forces retook the fort from the Japanese during the liberation of the Philippines in 1945, beginning on 27 March 1945.

Initial assaults were unsuccessful; the terrain was such that tanks could not bring their guns to bear on the Japanese positions.

On 31 March an attempt was made to burn out the defenders by pouring diesel fuel down the only vent shaft accessible to the Americans.

On 5 April over 2,500 US gallons (9,500 L) of diesel fuel were pumped down the vent shaft and ignited using white phosphorus mortar rounds.

The next few days were occupied with probing infantry attacks and attempts to persuade the surviving Japanese to surrender.
