The Marine Corps announced Wednesday that U.S. service members seen in another photo taken at Iwo Jima on Feb. 23, 1945 were also misidentified, two months after correcting the record on one of the most iconic images from World War II.

Amateur historians studied a number of photos shot during two flag-raisings atop Mount Suribachi during an intense battle between American and Japanese forces in 1945, and claimed the identifications made by the Marines of the six men in the famous photo by Associated Press photographer Joe Rosenthal included mistakes. In June of this year, after the review, the Marine Corps agreed.

A panel found that Private First Class Harold Schultz, of Detroit, was in the photo and that Navy Pharmacist's Mate 2nd Class John Bradley wasn't. 

That was the second U.S. flag-raising that day. The Marines then looked into a photo of the first flag-raising, and on Wednesday, officials said two men seen in the first photo were also misidentified.

The record now shows that 1st Lt. Harold G. Schrier, Plt. Sgt. Ernest I. Thomas, Jr., Sgt. Henry O. Hansen, Cpl. Charles W. Lindberg, Pharmacist Mate 2nd Class John H. Bradley and Pvt. Philip L. Ward were seen in the first flag-raising. Pfc. Louis C. Charlo and Pfc. James R. Michels were not in the photo, as previous records had stated, but officials said the two men were nearby.

Bradley, seen in the earlier photo but not the later photo, gained fame after his son, James, wrote a best-selling book about the flag raisers, "Flags of Our Fathers," which was later made into a movie directed by Clint Eastwood.

"My father raised a flag on Iwo Jima," James Bradley told The Associated Press in May. "The Marines told him way after the fact, 'Here's a picture of you raising the flag.' He had a memory of him raising a flag, and the two events came together."

More than 6,500 U.S. servicemen died in the battle at Iwo Jima, a tiny island 660 miles south of Tokyo that was deemed vital to the U.S. war effort because Japanese fighter planes based there were intercepting American bomber planes. The invasion began on Feb. 19, 1945, with about 70,000 Marines battling 18,000 Japanese soldiers for 36 days.

Besides those killed, about 20,000 Americans were wounded. Only about 200 Japanese soldiers were captured, with the others killed in the fighting.
