The defence of the Dunkirk perimeter held throughout 29–30 May, with the Allies falling back by degrees. On 31 May, the Germans nearly broke through at Nieuport. The situation grew so desperate that two British battalion commanders manned a Bren gun, with one colonel firing and the other loading. A few hours later, the 2nd Battalion, Coldstream Guards of the 3rd Division, rushed to reinforce the line near Furnes, where the British troops had been routed. The Guards restored order by shooting some of the fleeing troops and turning others around at bayonet point. The British troops returned to the line and the German assault was beaten back.
