At the conclusion of the war in 1945, the Congress of the United States commissioned de Weldon to construct the statue for the Marine Corps War Memorial (called Iwo Jima Memorial) in the realist tradition, based upon the famous photograph of Joe Rosenthal, of the Associated Press agency, taken on February 23, 1945. De Weldon made sculptures from life of three (on June 23, 2016, John Bradley was not believed to be in the photo) of the six servicemen raising the replacement United States flag on Mount Suribachi, on Iwo Jima. The other three flag-raisers who were killed in action (on June 23, 2016, Harold Schultz was identified as a flag-raiser in the photo and was not KIA) later on the island were sculpted from photographs. De Weldon took nine years to make the memorial which was dedicated on November 10, 1954, and was assisted by hundreds of other sculptors. The result is the 100-ton bronze statue which is on display in Arlington, Virginia.
