Following the events at Dunkirk, the German forces regrouped before commencing operation "Fall Rot", a renewed assault southward, starting on 5 June. Although the French soldiers who had been evacuated at Dunkirk returned to France a few hours later to stop the German advance and two fresh British divisions had begun moving to France in an attempt to form a Second BEF, the decision was taken on 14 June to withdraw all the remaining British troops, an evacuation called Operation Ariel. By 25 June, almost 192,000 Allied personnel, 144,000 of them British, had been evacuated through various French ports. Although the French Army fought on, German troops entered Paris on 14 June. The French government was forced to negotiate an armistice at Compiègne on 22 June.
