When did the Japanese Army attack Pearl Harbor?

The Japanese army attacked Pearl Harbor on December 7, 1941. This surprise attack on the American naval base in Hawaii was a crucial moment in the Second World War. Conceived by the Commander-in-Chief of the Japanese Combined Fleet, Admiral Isoroku Yamamoto, the operation was designed to neutralize American naval power in the Pacific.

On the morning of December 7, successive waves of Japanese aircraft attacked the warships and military installations at Pearl Harbor. In just under two hours, they inflicted considerable damage on the American fleet, sinking four battleships, damaging four others and destroying hundreds of aircraft. More than 2,400 American servicemen and civilians lost their lives, and around 1,000 others were wounded.

The consequences of the Pearl Harbor attack were immediate and far-reaching. The following day, December 8, 1941, President Franklin D. Roosevelt made a memorable speech to Congress, calling December 7 an infamous date. Congress then voted to declare war on Japan, marking the United States’ official entry into the Second World War.

This event radically changed the course of the war and consolidated the alliance between the USA, the UK and the Soviet Union against the Axis powers. The attack on Pearl Harbor is often studied as an example of military strategy and major geopolitical impact.

The Japanese army attacked Pearl Harbor on December 7, 1941, an event that led to the entry of the United States into the Second World War and had a significant impact on the outcome of the conflict.
