Operation Manhole

'Manhole' was an Allied special forces gliderborne mission to deliver a Soviet liaison team from southern Italy into German-occupied Yugoslavia (23 February 1944).

General Leytenant Nikolai V. Korneyev and General Major Anatoli P. Gorshkov had refused to have their party delivered by parachute, so the British arranged to deliver them and their party in two Airspeed Horsa gliders under fighter cover.
