Some battles, such as the Battle of Iwo Jima, had no civilians present, but Okinawa had a large civilian population. The civilians killed or injured in the battle were at least 150,000. American deaths were 18,900 killed or missing and 53,000 injured, more than double of the soldiers killed at Iwo Jima and Guadalcanal put together. Several thousand soldiers who died from wounds and other causes after the battle had finished, are not included. About a third of the civilian population of the island were killed.
