The Ancre at Albert.
The Battle for Amiens.
The Allies consolidate their front and counter-attack.
After the fall of Montdidier, the fourteen divisions of von Hutier's army converged towards the pocket to the south-west.
Seven other divisions, marching against the British front between the Somme and Arras, suddenly turned south. On the 28th, 80,000 Germans made for the gap, through which 160,000 men of von Hutier's army were already pressing. In all, 240,000 men were about to attack on a seventeen-mile front.
General Humbert's left maintained an aggressive defensive.
On March 28, they counter-attacked. The 4th Zouaves captured Orvillers and Boulogne-la-Grasse, threatening the enemy on the flank at Montdidier. Seeing the danger, the Germans retook part of the conquered positions. The moral effect was, however, considerable, indicative as it was of the Allies' determination to re-act.
