The most famous British actions using gliders included the unsuccessful Operation Freshman, against a German heavy water plant in Norway in 1942; and the capture of the Caen canal and Orne river bridges in a coup-de-main operation at the very start of the invasion of Normandy. Other glider actions included Operation Dragoon (the invasion of southern France), Operation Market Garden (the landing at Arnhem Bridge to try and seize a bridgehead over the lower Rhine) and Operation Varsity (crossing of the Rhine). Out of the 2,596 gliders dispatched for Operation Market Garden, 2,239 were effective in delivering men and equipment to their designated landing zones.
