The aircraft warning serv- ice was put into operation, with civilians hurriedly manning their observation posts. Amateur radio stations were ordered off the air, and unnecessary civilian flying was prohibited. The War Department ordered the immediate movement of reinforcements for the Pacific coast by air and fast trains. The supply of heavy bombers was so limited that it was not found possible to immobilize any large number by assigning them to stations along the coasts. Locally based air units therefore consisted in large part of fighter aircraft, to which were added antiaircraft artillery, barrage balloons, and searchlights. The first reinforcement to reach the Pacific coast consisted of planes of the 1st Pursuit Group, which arrived at San Diego on 8 December; by 2 2 December this entire P-38 group had been transferred from Michigan to California. An additional augmentation of pursuir strength was pro- vided in mid-December by the temporary assignment to the Fourth Air Force of a Marine unit, Air Wing I . Meantime, antiaircraft artil- lery units had begun to reach the West Coast from inland stations, and some regiments which were at ports of embarkation were diverted to coastal defense as~ignments.~~ As these and other forces took up their defensive positions, coastal communities suffered from an “invasion fever” which first showed itself with the calling of an alert in San Francisco on 8 December. In the afternoon of the 8th, rumors of an enemy carrier off the coast led to the closing of schools in Oakland.“’ That evening, while residents of the Bay area were having dinner, radio broadcasting suddenly ceased, and this was followed by a blackout which lasted nearly three hours. In the absence of adequate preparations, sirens on police cars were used to warn the people, and self-appointed neighborhood wardens rushed from door to door to help enforce the blackout.
