World War 2: Island Hopping Battles in the Pacific (2024)

Battles of WW2 in the Pacific

When Japan made a surprise attack on Pearl Harbor on December 7, 1941,President Franklin D. Roosevelt described it as a "date which will live in infamy." Over 2,400 American servicemen were killed in the devastating attack and America was immediately brought into World War 2.

The U.S. would be fighting a war on two fronts: in Europe and in the Pacific. Despite the Japanese attacking the U.S.,America's leading generals thought defeating Germany was the more pressing concern. That was where the majority of U.S. forces went at first.

General Douglas MacArthur and Admiral Chester Nimitz were in charge of U.S. forces in the Pacific. They devised a strategy of "island hopping" to defeat Japan.

The "island hopping" plan involved winning battles on Pacific islands togain military bases and moving across the Pacific Ocean and closer to Japan. This strategy would span three years and would take U.S. forces in almost a full circle around the Pacific.

In many ways, the Battle of Midwaywas the turning point in which the U.S. began putting this plan into action. In June 1942, the U.S. Navywon an important victory over the Japanese andinflicted devastating damage on its fleet. Aircraft carriers proved to be the most important resource in the Pacific and Japan lost four of them at Midway.

From April to June of 1945, American and Japanese forces engaged in the brutal 82-day Battle of Okinawa. The battle resulted in the highest number of casualties on both sides in the Pacificand was nicknamed the "kotetsu no hageshi kaze" or"typhoon of steel". In desperation, Japan utilized suicide kamikaze attacks and eventually saw over 100,000 killed.
