The 26th Cavalry of the Philippine Scouts really distinguished themselves. A Lutenaant made the mistake of lighting a cigarette early one morning. An ambushed machine gunner yelled that was the wrong thing to do and they were riddled by the Japanese, losing about 500 hundred mounts, eight officers, and many unlisted men. They were covering the flank. The Philippine Army retreated and left them cut off. They had to take to the mountains around Lingayen and get reorganized.
