On 23 August Longwy's 2,600-man French garrison surrendered to 13,731 Austrians with 48 guns and 18,200 Prussians with 88 guns. Verdun's garrison of 4,128 men capitulated to Brunswick on 2 September. In the crisis, the new French army commander Charles François Dumouriez sent Arthur Dillon with an advance guard including the 12th Chasseurs on a false attack toward Stenay. Dumouriez marched the main army south from Sedan, reaching Grandpré on 3 September while Dillon raced ahead to occupy Les Islettes. On 12 September Brunswick broke through Dumouriez's defenses at La Croix-aux-Bois by beating Jean-Pierre François de Chazot's division.
