The outcome of the battle.
The U.S. brought out their tanks and kept pushing, and pushing everyday until so many Japanese soldiers were killed, that Japan lost hope. Then, U.S. seized the island, and some of its people. Some of the people were used for labor. Like feeding the soldiers, doing laundry, and things like that.
The allies won because they fought so hard even though they lost a lot of soldiers too, they didn't give up like Japan did
