As we resume our advance, I hear what appear to be four bursts of static from an infiltration warning device speaker, followed by four violent blasts, probably the explosions of landmines buried in the area. Now there can be no delay. I blow the whistle for the assault. The results achieved are the destruction of 12 or 13 men, three medium field shelters and two 45mm mobile guns with their vehicles. We continue the advance, still seeking the enemy. Recovering from their shock, enemy soldiers oné by one commence firing from the ridge line extending in front of us. Undeterred, we continue to advance.
