About 14,000 Army and Marine Corps personnel were killed, wounded, or missing in action. Almost the entire Japanese force of about 30,000 were killed.
There were so many people charging the Americans that machine-gunners could hit people anywhere they fired. Thousands of people died. It was over, but it inflicted pain and terror. At the end of the battle the U.S. suffered the total casualties of 14,224 troops (out of which 3,144 were killed, 128 missing and 10,952 wounded in action). But almost every single Japanese soldier died in the futile but determined attack.
