THE ALLIED DEFENSIVE
Before 7 December 1941, while war was actively being waged
in Europe and the Far East, the United States, still a neutral, was
expanding its manufacturing facilities to meet the demands for
additional war materials, both for the growing U.S. forces and
those of the Allies. On 7 December the Japanese struck Pearl
Harbor in an attempt to so cripple U.S. naval power that future
Japanese conquest and occupation in the Pacific would meet with
little or no opposition. This attack dealt a serious blow to Navy and
Army Air Forces units stationed in the Hawaiian Islands. On the same
day two Japanese destroyers attacked the island of Midway, but were
beaten off by the defending troops. On 8 December Wake was
assaulted. The attacks on Wake were continued for two weeks and
the small U.S. garrison was forced to surrender on 23 December.
Another weak garrison on the island of Guam, unable to resist the
enemy attacks, fell on 10 December.
Early on the morning of 8 December the U.S. forces in the
Philippines were notified that a state of war existed and a full
war alert was ordered. On the same day the first Japanese aerial
attack on the Philippines took place. This was followed by others
and on 10 December enemy landings were made on Luzon. Expecting
an early victory, the Japanese sent a large force, but it was not
until 6 May 1942 that the Japanese were able to conquer the
American and Filipino defenders who fought a delaying action
down the Bataan Peninsula and made a final stand on the island
of Corregidor. All military resistance ended in the rest of the
Philippine Islands by 17 May except for small bands of guerrillas
who continued to fight the enemy until 1945 when the U.S. forces
landed in the Philippines. In March 1942 the commander of the
United States Army Forces in the Far East was ordered to move to
Australia by the President of the United States. Troops from the
1 See Louis Morton, The Fall of the Philippines, in preparation for the series U. S. ARMY
IN WORLD WAR II.
United States began arriving in Australia in December 1941 for
the build-up in preparation for the defense of Allied bases and
the recapture of enemy-held islands and bases in the Pacific.
While some Japanese forces were carrying out the attacks in the
Pacific, others were overrunning Malaya, North Borneo, and Thailand.
After eighteen days of fighting Hong Kong was captured on
25 December 1941. Thailand, unable to resist the Japanese, agreed
to co-operate with them. Early in 1942 the Japanese took Borneo
and by 15 February the British garrison in Malaya capitulated. In
the Netherlands East Indies the U.S. Navy inflicted damage on an
enemy convoy in the Battle of Makassar Strait, the first important
surface action of the war for the U.S. Navy. On 9 March 1942 formal
surrender by the Dutch ended all resistance in the Netherlands
East Indies. By these conquests in Asia and the Pacific, the Japanese
gained valuable territory rich in natural resources and were ready
to expand in other directions.
During the first six months of 1942 the U.S. Navy fought the
Japanese Navy in the Battle of the Coral Sea and the Battle of
Midway, and raided the Marshall and Gilbert Islands. Army Air
Forces medium bombers took off from a carrier at sea and bombed
Tokyo in April 1942 in a surprise attack. As part of the Midway
operations in June, planes of the Japanese Navy bombed U.S. installations
in Alaska and enemy troops landed in the Aleutian Islands
on Attu and Kiska.
The Allied defensive phase of the war in the Pacific ended on
6 August 1942, with the Allies ready to strike the enemy-held
islands in the South Pacific.
INFANTRYMEN DURING A FIELD INSPECTION in the Hawaiian Islands,
January 1941. From 1935 on the U.S. garrison in the Hawaiian Islands was larger
than any other American overseas outpost. However, by 1940 there was a
shortage of modern equipment and trained personnel, and not until February
1941 did troop reinforcements and up-to-date equipment begin to arrive in
Hawaii. The United States was not prepared for war and the men and equipment
did not meet the necessary requirements.

defense of the Hawaiian Islands had been set up and joint maneuvers (land, air,
and naval forces) were held periodically to test the various security measures.

Oahu, in the Hawaiian Islands. Early in December 1941 all the U.S. troops,
including antiaircraft batteries, were returned to their stations from field maneuvers
to await the signal for riot duty. Trouble was expected, and while Japanese
diplomats in Washington talked peace, their Pearl Harbor Striking Force was
moving eastward toward Hawaii. During this movement the fleet maintained
radio silence and was not detected as it approached the islands. (.50-caliber antiaircraft
machine gun, water-cooled, flexible.)
