The attack at Verdun was entrusted to Guillaumat, and his bombardment began on 17 August. The Germans anticipated an offensive on the left bank of the Meuse, but not the extension which Guillaumat had planned on the right bank as well. The weather was as fair at Verdun as it was foul in Flanders, and while Haig's men floundered in seas of mud, the worst against which Pétain's had to contend was clouds of dust. Their artillery had destroyed the German defences on Mort Homme, and when the infantry advanced on the 20th they carried it, the Avocourt wood, the Bois de Cumières, and the Bois des Corbeaux, in a few hours with little loss. Simultaneously on the right bank of the river they captured Talou Hill, Champneuville, Mormont farm, and part of the Bois des Fosses. On the following day the Cote de l'Oie and Regnéville fell on the left bank, and Samogneux on the right. On the 24th the French took Camard wood and Hill 304 and advanced to the south bank of the Forges brook, which remained their line until the American attack in October 1918, while further progress was made east of the Meuse on the 25th until the outskirts of Beaumont were reached. A fortnight later another slight advance was made between Beaumont and Ornes, and on both banks of the Meuse the line was at length restored to almost its position before the great German offensive of 21 February 1916. But Brabant-sur-Meuse, Haumont, Beaumont, and Ornes remained in German hands, and no attempt had been made to recover the line the French had then held on the road to Étain (see Map, p. 194). Verdun might now have been thought quite secure but for the fact that equal success on the Chemin des Dames in October did not save it from the Germans seven months later.
