We were all astounded today to learn of the bombing of Hawaii by Japanese planes. First information was very meager. Naturally, only one conclusion is to be drawn—we are at war with Japan even though no announcement of any kind has been made. In our office, immediate steps were taken to shift all troops into their defense positions, and I held a conference this a.m. on plans for supply. Railheads are to be established at once, and automatic supply begins within 48 hours. Troops moving into position are taking with them two days of Class I [rations]. Troops are being moved to new positions by buses which are being assembled from the big fleet operators. Everyone wants transportation, and my office is having a trying time in an effort to meet demands.
