The battlefield's 2nd largest monument, the Eternal Light Peace Memorial, was accepted by President Franklin D. Roosevelt and unveiled at the 1938 Gettysburg reunion that attracted over 300,000 battlefield visitors. In 1939, the 1st of the Gettysburg National Museum's 14 expansions was completed (the electric map auditorium was added in 1963 and closed April 13, 2008). Pitzer Woods was the site of the World War II Camp Sharpe, and McMillan Woods had a German POW camp (the latter was used for post-war housing of migrant workers for local production). Heads-of-state at the battlefield included a 1943 Winston Churchill auto tour with President Roosevelt, President Eisenhower escorting President Charles De Gaulle (1960), and President Jimmy Carter hosting President Anwar Sadat and Prime Minister Menachem Begin (1978).
