Lanrezac declined to attack as Joffre wished on 21 August as the BEF were not yet in position on his left. With the French Third and Fourth Armies now attacking into the Ardennes, Lanrezac also declined to send reinforcements to Namur, which he had been warned would not hold out. On 22 August Lanrezac attempted to drive the Germans across the Sambre and failed. Later that day the German Second Army attacked the French Fifth Army and forced bridgeheads across the Meuse. Within a fortnight, Joffre had sacked one of the French corps commanders—General Sauret of III Corps, who had disappeared during the battle, leaving the corps artillery commander to take charge—and three of the four division commanders involved. Lanrezac had 193 battalions and 692 guns.
