Crusade in the Pacific looks at the battle of Okinawa. American Army and Marine forces land unopposed and meet little resistance as they split the island in half. Later, as armies move north and south, fighting grows more fierce. Allied forces eventually capture the north half of the island. In the southern half, stiff Japanese resistance and rain bog down offensive operations. After weeks of fighting the advancing American troops eventually overwhelm defenders. In the end, the Battle of Okinawa proves costly for both sides.
