Jacobs claimed he was reassigned from F Company to E Company, 2/28 Marines, on February 23, 1945, and he was the radioman ordered up Mt. Suribachi with Lt. Schrier and his 40-man patrol after a 4-man reconnaissance patrol from F Company went up and down Mt. Suribachi before hand. The other men involved in the patrol and first flag raising have all died. Annette Amerman, a historian with the Marine Corps History Division, said there are many that believe Jacobs was the radioman. However, there are no official Marine Corps records produced at the time that can prove or refute Mr. Jacobs' location. There has not been a Marine photo of Marshall to compare to Lowery's photos. There are however, photo comparisons of Jacobs that do verify he is the radioman with Lt. Schrier on Mount Suribachi, and several Los Angeles newspaper accounts (Associated Press Dispatch, beginning February 24, 1945) support Jacobs's testimonies that he was personally interviewed at Mt. Suribachi after the first flag-raising. His claims are also supported by his letters home.
