Major Battles of WWII in the
Pacific
Date: April to May 1942
Who was involved: Japan vs. Philippines and
U.S.
Significance: Facing starvation, this marked the
surrender of the Philippines to Japanese forces.
Results: 75,000 U.S. and Filipino soldiers were
forced to march 65 miles. Thousands of troops
died because of the brutality of their captors, who
starved and beat the marchers, and bayoneted
those too weak to walk.
Bataan Death March
Date: May 1942
Who was involved: Japan vs. U.S.
Significance: This battle prevented the
Japanese from invading Australia

sides more than half of their planes. Both
sides also lost aircraft carriers.
Battle of the Coral Sea

carriers in the battle.
Battle of Midway

marines with their first taste of jungle warfare.
Battle of Guadalcanal

destroyed what was left of the Japanese navy.
Battle of Leyte Gulf
Date: Feb. – March. 1945

of the war and showed that the closer the U.S. was

inevitable allied invasion of the Japanese islands at
the time.

Okinawa. Japanese pilots had flown nearly 2,000
Kamikaze attacks against the U.S. fleet.
