The siege of Calais (1940) was a battle for the port of Calais during the Battle of France. The siege was fought at the same time as the Battle of Boulogne, just before Operation Dynamo, the evacuation of the British Expeditionary Force (BEF) through Dunkirk. After the Franco-British counter-attack at the Battle of Arras (21 May), German units were held back to be ready to resist a resumption of the counter-attack on 22 May, despite the protests of General Heinz Guderian, the commander of the XIX Armee Korps, who wanted to rush north up the Channel coast to capture Boulogne, Calais and Dunkirk. An attack by part of the XIX Armee Korps was not authorised until 12:40 a.m. on the night of 21/22 May. By the time the 10th Panzer Division was ready to attack Calais, the British 30th Infantry Brigade and 3rd Royal Tank Regiment (3rd RTR) had reinforced the French and British troops in the port. On 22 May, the British troops had established roadblocks outside the town and French rearguards skirmished with German armoured units, as they advanced towards Calais. British tanks and infantry had been ordered south to reinforce Boulogne but were too late.
