There was a more satisfactory proportion of gains to losses in the more limited operations which characterized Pétain's substitution for Nivelle as French commander-in-chief. After Nivelle's comprehensive disappointment on the Chemin des Dames and Moronvillers heights in April, Pétain restricted the field of his attacks and took ample time to prepare them. It was not until August that the first was launched, and for a sphere of action Pétain reverted once more to Verdun. The victories of October and December 1916 were commonly represented as having recovered all that the Germans had won in the spring of that year; in fact they were confined to the right bank of the Meuse. No attempt had been made to wrest from the enemy his gains to the left of the river; and his line ran in August 1917 precisely where it had run twelve months before, a German gain at the Col de Pommerieux on 28 June having been recovered by the French on 17 July. Pétain was, however, a past-master in the art of limited offensives; his aims were less ambitious than those which Nivelle or even Haig had set before themselves, but he achieved them with scientific precision and without the devastating losses which had attended the larger and less successful projects. The terrain he selected was less affected by the vagaries of the weather, and either he was better served by his meteorological experts or was singularly favoured by fortune. His main object was not the tactical gains he secured, but the restoration of the confidence of French soldiers in their offensive capacity which had been severely shaken in April. During June and July they had been mainly engaged in repelling German attacks on the Chemin des Dames, though Gouraud, who succeeded Anthoine in the Champagne command, secured some valuable local gains on the Moronvillers heights.
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.
