Operation Cycle is the name of the evacuation of Allied troops from Le Havre, in the Pays de Caux of Upper Normandy from 10–13 June 1940, towards the end of the Battle of France, during the Second World War. The operation was preceded by the better known rescue of 338,226 British and French soldiers from Dunkirk in Operation Dynamo (26 May – 4 June). On 20 May, the Germans had captured Abbeville at the mouth of the Somme and cut off the main Allied armies in the north. South of the river, the Allies improvised defences and made local counter-attacks, to dislodge the Germans from bridgeheads on the south bank and re-capture river crossings for an advance northwards to regain contact with the armies in northern France and Flanders.
