Henry Oliver Hansen

A third Marine Corps investigation into the identities of the six second flag-raisers concluded in October 2019, that Harold Keller was in the Rosenthal's photograph in place of Rene Gagnon (fifth from left). Gagnon who carried the larger second flag up Mount Suribachi, helped lower the first flagstaff and removed the first flag at the time the second flag was raised. The identities of the other five flag raisers were confirmed. Like Schultz, Keller did not ever say publicly he was a flag-raiser or that he was in the photograph.

President Dwight D. Eisenhower sat upfront during the dedication ceremony with Vice President Richard Nixon, Secretary of Defense Charles E. Wilson, Deputy Secretary of Defense Robert Anderson, and General Lemuel C. Shepherd, the 20th Commandant of the Marine Corps. Ira Hayes, one of the three surviving flag raisers depicted on the monument, was also seated upfront with John Bradley (incorrectly identified as a flag raiser until June 2016), Rene Gagnon (incorrectly identified as a flag raiser until October 16, 2019), Mrs Martha Strank, Mrs. Ada Belle Block, and Mrs. Goldie Price (mother of Franklin Sousley). Those giving remarks at the dedication included Robert Anderson, Chairman of Day; Colonel J.W. Moreau, U.S. Marine Corps (Retired), President, Marine Corps War Memorial Foundation; General Shepherd, who presented the memorial to the American people; Felix de Weldon, sculptor; and Richard Nixon, who gave the dedication address. Inscribed on the memorial are the following words:

The Marine Corps review board looked once more into the identities of the six second flag-raisers in Rosenthal's photograph, this time concluding in June 2016 that Harold Schultz was in the photograph and John Bradley was not. Franklin Sousley, not Schultz, is now in the position initially ascribed to Bradley (fourth from left) in the photograph and Schultz is now in Sousley's former position (second from left) in the photograph. The identities of the other five flag-raisers were confirmed. Schultz did not ever say publicly that he was a flag-raiser or in the photograph.

On March 14, an American flag was officially raised up a flagpole by orders of Lieutenant General Holland Smith at the V Amphibious Corps command post on the other side of Mount Suribachi where the 3rd Marine Division troops were located, and the second flag which was raised on February 23 on Mount Suribachi came down. Lt. Col. Johnson was killed in action on March 2. Sgt. Genaust was killed on March 4 in a Japanese cave on Iwo Jima, and his remains are still missing. Sgt. Strank and Cpl. Block were killed on March 1, and Pfc. Sousley was killed on March 21.

Hank Hansen is featured in the 2006 Clint Eastwood movie Flags of Our Fathers, where he is played by American actor Paul Walker. The movie is based on the book of the same title.

Sergeant Henry O. Hansen Park, in his hometown of Somerville, was named in his honor in June 2004.

The second flag-raising by six Marines was photographed by Associated Press combat photographer Joe Rosenthal and became famous after copies of his photograph appeared in the newspapers two days later. He was incorrectly identified in Rosenthal's flag-raising photograph as the Marine at the base of the flagstaff until the Marine Corps announced in January 1947 after an investigation which was initiated by one of the flag-raisers, that Corporal Harlon Block was that Marine. Hansen is one of three men who were originally identified incorrectly as flag-raisers in the photograph (the others being John Bradley and Rene Gagnon).

A Marine Corps investigation of the identities of the six second flag-raisers began in December 1946 and concluded in January 1947 that it was Cpl. Block and not Sgt. Hansen at the base of the flagstaff in the Rosenthal photograph, and that no blame was to be placed on anyone in this matter. The identities of the other five second flag-raisers were confirmed.

Hansen landed with the 5th marine Division on Iwo Jima, on February 19, 1945. He landed with his rifle company and battalion at the southern end of Iwo Jima where Mount Suribachi is located.

On February 23, 1945, Lieutenant Colonel Chandler W. Johnson, commander of the 2nd Battalion, 28th Marine Regiment, ordered a platoon-size patrol to climb up 556-foot Mount Suribachi. Captain Dave Severance, E Company's commander, assembled the remainder of his Third Platoon and other members of the battalion headquarters including two Navy corpsmen and stretcher bearers. First Lieutenant Harold Schrier, E Company's executive officer, was handed the Second Battalion's American flag from Lt. Colonel Johnson (or the battalion adjutant); the flag measured 28 by 54 inches (137 by 71 cm) and had been taken from the attack transport USS Missoula (APA-211) on the way to Iwo Jima by First Lieutenant George G. Wells the Second Battalion's adjutant in charge of the battalion's flags. Lt. Schrier was to it take a patrol with the flag up the mountain and raise the flag if possible at the summit to signal that Mount Suribachi was captured and the top secure. At 8:30 a.m., Lt. Schrier started climbing with the patrol up the mountain. Less than an hour later, the patrol, after receiving occasional Japanese sniper fire, reached the rim of the volcano. After a brief firefight there, Lt. Schrier and his men captured the summit.

Sgt. Hansen was killed in action on Iwo Jima on March 1. Sgt. Hansen, Platoon Sgt. Thomas, and the three second flag-raisers who were killed on Iwo Jima were buried in the 5th Marine Division cemetery on the island. The battle of Iwo Jima officially ended on March 26, 1945, and the next day the 28th Marines left the island for Hawaii. Hansen's final burial was at the National Memorial Cemetery of the Pacific near Honolulu on the island of Oahu in Hawaii.

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).

The Marine Corps War Memorial (also known as the Iwo Jima Memorial) in Arlington, Virginia, which was inspired by Joe Rosenthal's photograph of the second flag-raising on Mount Suribachi by six Marines on February 23, 1945, was dedicated on November 10, 1954 (179th anniversary of the Marine Corps). Harold Schrier, Charles Lindberg, and Lou Lowery, from the patrol that raised the first flag on Mount Suribachi, attended the dedication ceremony as guests.

Hansen volunteered for the Paramarines, which were formed in 1942, and became a Marine parachutist. He fought in the Bougainville Campaign in 1943. In February 1944, the Paramarines were disbanded and he was transferred to Third Platoon, Company E, 2nd Battalion, 28th Marines, 5th Marine Division at Camp Pendleton, California.

Hansen was born in Somerville, Massachusetts, with one sister and three brothers. He graduated from Somerville High School in 1938 and joined the Marine Corps.
