Harris, Barnes Wallis and various RAF officers waited at St Vincents before receiving confirmation that the raid had indeed breached Germany’s Möhne and Eder dams. In 1944 the building became the headquarters for the USAAF Air Force’s 9th Troop Carrier Command and the co-ordination centre for another major aviation milestone; the allied airborne assault for D-Day. 9th Troop Carrier Command remained there until mid-1945 to include brief joint tenancy arrangement with 7 Group Bomber Command, who oversaw all training units. Post-World War II the hall was retained by the Air Ministry, mainly on a Care and Maintenance basis until it was sold in 1978 to South Kesteven District Council. Today, St Vincents Hall is privately owned. Visits to the site by invitation. St Vincents Hall, Grantham RAF roundel in the grounds of St Vincents 39
