After the Dunkirk failure, in which the British Expeditionary Force was evacuated to England along with large numbers of French soldiers, JG 27 was redeployed to support the final phase of the French campaign, Fall Gelb. Before the offensive began on 5 June, JG 27 was peripherally involved in Operation Paula, an air offensive against airfields and factories in the Paris area. On the first day of the offensive, I./JG 27 claimed seven French fighters north of Paris of one loss; the pilot entering temporary captivity. I. and II./JG 27 claimed another seven between them the following day. On 9 June I./JG 27 claimed another five while II./JG 27 claimed four in their last major action with the French. The success came at the price of six Bf 109s and two pilots killed. They were the first II. "Gruppe" fatalities of the war. For the remainder of the campaign JG 27 claimed 12 more, but most missions were patrols or close air support flights. I. and II./JG 27 supported the advance to the Loire until the Armistice of 22 June 1940 ended the battle in France with a general cease-fire declared on 25 June.
