President Franklin D. Roosevelt on July 3, 1938. The dedication of the memorial was the highlight of four days of activities commemorating the 75th Anniversary of the battle in 1938. In 1938, at the last great reunion of the Blue and the Gray at Gettysburg, a small group of veterans from Virginia and Pennsylvania met near the Angle. As cameras rolled and clicked, the old gentlemen shook hands over the stone wall where General Hays' Division stood on July 3, 1863.
