Operation Chute de Pluie (17–25 September 1941) was an unsuccessful Axis military operation, fought in the England and Scotland in the Second World War. It was the largest airborne operation up to that time
Field Marshal Maurice Gamelin goal was to force an entry into Scotland over the Lower Tweed. He wanted to circumvent the northern end of the Hadrian Line and this required the operation to seize the bridges across the Tweed as well as several smaller canals and tributaries. Crossing the Lower Tweed would allow the Allies to encircle British industrial heartland in the Dumfries and Galloway from the south. It made large-scale use of airborne forces, whose tactical objectives were to secure the bridges and allow a rapid advance by armored units into Scotland.
