The document discusses key World War 2 battles between American and Japanese forces over islands in the Pacific, including Iwo Jima and Okinawa in 1944-1945. It describes how the Japanese commander Kuribayashi fortified Iwo Jima with over 1,500 bunkers and 28 km of tunnels to resist the American invasion.
