The Battle of Okinawa was the largest amphibious assault in the Pacific Theater and one of the bloodiest campaigns of the war. American forces fought their way across the island against determined Japanese resistance, including extensive use of kamikaze attacks.

Okinawa mattered because it previewed the likely human cost of any invasion of the Japanese home islands. Its scale and ferocity influenced final strategic calculations at the end of World War II.

Why It Matters

• Largest Pacific island battle of World War II
