Operation Hirondelle
Introduction '''Operation Hirondelle''' took place during the First Indochina War in July 1953.It was an airborne raid on Viet Minh supply depots near Lạng Sơn, involving parachute units of the French Army and Vietnamese National Army. Raids near the junction of Route Coloniale 4 and Route Coloniale 1 revealed supply caches hidden in caves, which were photographed and destroyed.The attack forces then retreated over land through Loc Binh, where other French units had been dropped on July 17 to repair and hold a river crossing for the retreating units; and then to form a rearguard for 20 miles. The entire force rendezvoused with Groupe Mobile Five, and was then extracted by sea on July 19, suffering from heat exhaustion. The average weight loss was 11 pounds.
