Earlier this month the Marine Corps announced the third change in the official identification of the six Marines who raised the Flag at Iwo Jima in the famous 1945 photo by AP photographer Joe Rosenthal. The findings of historians Stephen Foley, Dustin Spence and Brent Westemeyer using other period photos and film were confirmed by a special investigative board convened by the Marine Corps and by investigators from the FBI's Digital Evidence Laboratory.
They concluded that Cpl. Harold "Pie" Keller of Brooklyn, Iowa, and not Pfc. Rene Gagnon, was one of the flag-raisers in the Rosenthal photograph. The previous two “corrections” in the immortal line up were in 1947 when it was concluded that Cpl. Harlon Block was misidentified as Sgt. Hank Hansen, and in 2016 when it was concluded that Cpl. Harold Schultz was misidentified as Hospital Corpsman John "Doc" Bradley. The other three men in the photo that have been consistently identified since 1945 are Pfc. Franklin Sousley, Sgt. Michael Strank and Cpl. Ira Hayes.
Apparently, the origin of the flag in Rosenthal’s photo (the second and more famous of two photos taken) is claimed by the Navy to be LST 779, while the Coast Guard claims it originated from LST 758.
My question is this. Has the research been done to confirm which transports carried each of the Iwo Jim flag-raisers to Iwo Jima? I figured if anyone would know, it would be one of the Marine collectors/researchers here.
