At 6 a.m. General Sutherland phoned me that the Japanese had treacherously attacked Pearl Harbor at 5 a.m. and consequently the U.S. and Philippine Forces were in a state of war with Japan. I notified by phone all the members of my General Staff. Rushed to the office. At 9 a.m. I received news that Japanese planes had bombarded Davao Harbor and Airfield, destroying them. At 12.20 p.m. the Air Raid alarm was sounded. Japanese planes bombarded Clark field killing and wounding many and destroying 17 bombers and other smaller planes.
