Camp Griffiss was a US military base in the United Kingdom during and after World War II. Constructed within the grounds of Bushy Park in Middlesex, (now in the London Borough of Richmond upon Thames), England, it served as the European Headquarters for the United States Army Air Forces from July 1942 to December 1944. From here Dwight D. Eisenhower planned the D-Day invasion. Most of the camp's huts had been removed by the early 1960s, and a memorial tablet now stands on the site.
