Jacobs participated in the Battle of Iwo Jima which began on February 19, 1945. On February 23 at 8 AM, First Lieutenant Harold Schrier, the E Company executive officer, led a 40-man combat patrol from Third Platoon, E Company, 2nd Battalion, 28th Marines up Mount Suribachi to siege and occupy the crest. Accompanying Schrier was Jacobs, a radioman from F Company who was assigned to him for the patrol. Schrier was to raise an American flag he was given to signal that the mountaintop was captured. Once on top of the volcano, a section of a Japanese water pipe was found that became the flagstaff for the flag. Schrier and two other Marines attached the flag to the pipe which was then carried to the highest spot on the crater. At approximately 10:20-10:35 a.m., Lt. Schrier, Platoon SergeantErnest Thomas, and Sergeant Henry Hansen, raised the flag. Seeing the raising of the national colors immediately caused a reaction of loud cheering from the Marines, sailors, and coast guardsmenon the beach below and from the men on the ships near the beach; the ships whistles and horns went off too. Hansen was killed in action on Iwo Jima on March 1, and Thomas on March 3. On March 10, 1945, Jacobs was wounded by enemy mortar fire and was evacuated off Iwo Jima. The actual raising of the first flag on Mount Suribachi had not been photographed. In the early afternoon, a larger replacement flag was brought up Mount Suribachi by the Easy Company runner which was then attached unto another Japanese steel pipe. This flag was raised by six servicemen while the first flag was lowered. A photograph of the second flag raising by Associated Press photographer Joe Rosenthal appeared in the newspapers, became renowned world-wide, made the second flag-raisers and Rosenthal famous, and led to the creation of the huge Marine Corps War Memorial in 1954, in Arlington, Virginia.
Post World War II
Jacobs was honorably discharged from the Marine Corps in 1946. He then went to work as a reporter, news anchor, and news director for KTVU in Oakland, California for 34 years before retiring in 1992. In 1950, Jacobs was called up for Marine Corps service during the Korean War. He served as a Marine instructor in California until he was honorably discharged with the rank of sergeant in 1951.
World War II photo claim
Jacobs and his family spent his later years trying to prove that he was the Marine radio operator who was photographed several times by Staff Sergeant Louis R. Lowery, on top of Mount Suribachi, standing beneath the first American flag. Although Jacobs's face is not visible in Lowery's most widely circulated photograph of the first flag flown on Mount Suribachi, his claim that it is definitely him was based on other photographs of him taken by Lowery and other combat photographers near the first flag with Lieutenant Schrier. The radioman in the most famous of Lowery's photographs was assumed for years to be an unknown Marine, an F Company Marine rifleman named Louis Charlo, or Pfc. Gene Marshall, the E Company radio operator. Marshall, who died in 1987, claimed he was on Mount Suribachi, on February 23. Jacobs disputed the official identifications in Lowery's picture and asserted that it should be: Pfc. James Robeson, Pfc. Raymond Jacobs, 1st Lt. Harold Schrier, Sgt. Henry Hansen, unknown Marine, Platoon Sgt. Ernest Thomas, PhM2c. John Bradley, USN, Pfc. James Michels, and Cpl. Charles Lindberg. 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 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. Due to an agreement with the Associated Press and the Marine Corps over Rosenthal's photo of the second flag raising on Mount Suribachi the afternoon of February 23, Lowery's photos taken on Mount Suribachi were not released until 1947, when 16 of his pictures appeared in Leatherneck Magazine.
