Saya mau tau Operation Ariel dari Pasukan Ekspedisi British (Perang Dunia Kedua). Jelaskan dalam bahasa melayu

From  following the military collapse in the Battle of France against Nazi Germany, British and Allied ships were covered from French bases by five RAF fighter squadrons and assisted by aircraft based in England to lift British, Polish and Czech troops, civilians and equipment from the French Atlantic ports, particularly St. Nazaire and Nantes. The Luftwaffe'' attacked the evacuation ships and on 17 June, sank the Cunard liner and troopship  in the Loire estuary. The ship sank quickly and vessels in the area were still under attack during rescue operations, which saved about  and crew but thousands of troops, RAF personnel and civilians were on board and at least  died.

Some equipment was embarked but lack of information about the progress of the German Army towards the coast, rumours and alarmist reports, 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 Operation Cycle from Le Havre, elsewhere along the Channel coast and the termination of Operation Ariel, another  troops were rescued, bringing the total of military and civilian personnel returned to Britain during the Battle of France to   British troops.
