On March 20, 1945, President Roosevelt ordered the flag-raisers in Rosenthal's photograph to Washington D.C. after the battle. Pfc. Gagnon was ordered to Marine Headquarters in Washington on April 3 and arrived on April 7. He was questioned the same day by a Marine public information officer about the identities of the six flag raisers in the photograph. Gagnon identified the six flag raisers as Sgt. Strank, Pfc. Sousley, Navy corpsman John Bradley, Pfc. Ira Hayes, and Sgt. Henry Hansen, and himself. He also said Sgt. Strank, Sgt. Hansen, and Pfc. Sousley were killed on Iwo Jima. After Pfc. Gagnon was questioned, Pfc. Hayes and PhM2c. Bradley were ordered to Marine Headquarters in Washington D.C. Bradley, who was recovering from his wounds at Oakland Naval Hospital in Oakland, California, was transferred to Bethesda Naval Hospital at Bethesda, Maryland, where he was shown Rosenthal's flag-raising photograph and was told he was in it. Both Bradley (on crutches) and Hayes arrived in Washington on April 19. They both reported to the same Marine officer as Pfc. Gagnon and were questioned separately. Bradley agreed with all of the identities of the flag-raisers named by Gagnon in the photograph including his own. Pfc. Hayes agreed with all of the identities named by Pfc. Gagnon except Sgt. Hansen, who was at the base of the flagstaff in the photo. Hayes said that person was Cpl. Block. The Marine lieutenant colonel told Pfc. Hayes that the identities were made public on April 8 and would not be changed, and to not say anything about it anymore (the officer later denied that Pfc. Hayes ever told him that Cpl. Block was in the photograph).
