Operation Aerial was the evacuation of Allied military forces and civilians from ports in western France. The operation took place from 15 to 25 June 1940 during the Second World War. The embarkation followed the Allied military collapse in the Battle of France against Nazi Germany. Operation Dynamo, the evacuation from Dunkirk and Operation Cycle from Le Havre, had finished on 13 June. British and Allied ships were covered from French bases by five Royal Air Force (RAF) fighter squadrons and assisted by aircraft based in England to lift British, Polish and Czech troops, civilians and equipment from Atlantic ports, particularly from St Nazaire and Nantes.
On 17 June, the Luftwaffe evaded RAF fighter patrols and attacked evacuation ships in the Loire estuary, sinking the Cunard liner and troopship HMT Lancastria which was carrying thousands of troops, RAF personnel and civilians. The ship sank quickly but nearby vessels went to the rescue and saved about 2,477 passengers and crew while under air attack. The death toll is unknown because the passenger count broke down in the haste to embark as many people as possible. Estimates of at least 3,500 dead make the sinking the greatest loss of life in a British ship. The British government tried to keep the sinking of Lancastria secret on the orders of the Prime Minister Winston Churchill.
Some equipment was embarked on the evacuation ships but alarmist reports about the progress of the German Army towards the coast led some operations to be terminated early and much equipment was destroyed or left behind. The official evacuation ended on 25 June, in conformity with the terms of the Armistice of 22 June 1940 agreed by the French and German authorities but informal departures continued from French Mediterranean ports until 14 August. From the end of Operation Dynamo at Dunkirk, Operation Cycle from Le Havre, elsewhere along the Channel coast and the termination of Operation Aerial, another 191,870 troops were rescued, bringing the total of military and civilian personnel returned to Britain during the Battle of France to 558,032, including 368,491 British troops.
