For those on the west side of the international date line, the "date which will live in infamy" came on 8 December 1941. Few responsible military or naval men had believed that the Japanese would be able to strike in more than one place. The number and diversity of their attacks took the Allies completely by surprise. During the early morning hours of the 8th, Japanese naval and air forces struck almost simultaneously at Kota Bharu in British Malaya (0140), Singora, just across the border in Thailand (0305), Singapore (0610), Guam (0805), Hong Kong (0900), Wake, and the Philippines.
The duty officer at Asiatic Fleet headquarters in the Marsman Building in Manila on the night of 7-8 December (Philippine time) was Lt. Col. William T. Clement, USMC. At 0230 of the 8th (0800, 7 December, Pearl Harbor time), the operator at the Navy station intercepted the startling message, "Air Raid on Pearl Harbor. This is no drill." Recognizing the technique of the sender, an old friend stationed at Pearl Harbor, the operator brought the message to Colonel Clement. Within a half hour, it was in Admiral Hart's hands. He broadcast the news to the fleet immediately, and then, with his chief of staff, hurried to his office.
Shortly after 0330 General Sutherland received the news of the Pearl Harbor attack, not from the Navy but from commercial broadcasts. He passed the news on to MacArthur over the private wire to the general's penthouse apartment in the Manila Hotel, then notified all commanders that a state of war existed with Japan.
