Another beautiful day but nothing much in the way of action has taken place. The units are still in place on the Reserve Battle Position, and there has been a certain amount of skirmishing, but no real action. The efforts of the Japs really seem to be centered in their efforts to make a successful landing on the west coast of Bataan. However, they have made no real effort to land in force. It is unusual tactics, to say the least, for they have these three isolated groups on the west coast, each one acting independently of the other. Of course, each one has a certain amount of nuisance value, for a larger force from our troops is required to clean it up. Then they operate differently from the usual procedure. Many of them get into trees, and they are hard to discover, even when the exact tree has been located. They tie themselves into the branches so they will not fall if hit, and the attacker never knows whether or not his fire is effective. However, the 57th Infantry and the 45th Infantry [PS] are going into these places today, and I believe they will clean up the small groups that remain. Am on duty tonight from 10:30 to 3 a.m., so have plenty of time to write. Another officer comes on to relieve me at 3 a.m. and he remains on duty until 7:30 a.m. tomorrow morning. Only one officer is required to be on duty during those hours, although I am usually here until 11:30.
