"" About eight o’clock, Miller and I were cautiously pacing our district. We came to a fence and were trying to see what the Filipinos were up to. Suddenly, near at hand, on our left, there was a low but unmistakable Filipino outpost signal whistle. It was immediately answered by a similar whistle about twenty-five yards to the right. Then a red lantern flashed a signal from blockhouse number 7. We had never seen such a sign used before. In a moment, something rose up slowly in front of us. It was a Filipino. I yelled “Halt!” and made it pretty loud, for I was accustomed to challenging the officer of the guard in approved military style. I challenged him with another loud “halt!” Then he shouted “halto!” to me. Well, I thought the best thing to do was to shoot him. He dropped. If I didn’t kill him, I guess he died of fright. Two Filipinos sprang out of the gateway about 15 feet from us. I called “halt!” and Miller fired and dropped one. I saw that another was left. Well, I think I got my second Filipino that time..."--Private William W. Grayson, with another soldier, encountered three armed Filipinos on a bridge in San Juan del Monte near Manila."
