On the 26th, the Crown Prince renewed and developed the attack, which, on the 29th, extended from the Four-de-Paris to about two miles beyond the Binarville-Vienne-le-Château road. After a three days’ bombardment, he hurled at least 40,000 men into action, three times in succession. Against the salient from Bagatelle to the north of Four-de-Paris alone, on a front of about five miles, he launched two divisions. Thanks to a hail of shells and gas bombs, the enemy advanced and, through the corridor of the Biesme, came within five miles of their objective, the railway station of Les Islettes. The fire of the 75’s, however, barred the road, and the French reserves subsequently counter-attacked and retook the lost ground covered with enemy dead. After some local attacks on July 2 and 7, the Germans launched a fresh general attack on the 13th, from the Binarville-Vienne-le-Château road, as far as the Haute-Chevauchée. After a bombardment with more than 45,000 shells, five regiments of the XVIth Corps rushed the shattered trenches. It was a powerful thrust, especially on the east, where a few trenches were lost; but in the course of several days’ fighting the enemy was held, and on the 14th the French counter-attacked on the west, pushed the Germans back north of the Servon road, and held for a short time the Beaurain Wood to the west of this road. On September 7, the enemy once more threw two divisions against the western side of the forest; but in this attempt, as in the first, they failed to break through. In September, 1915, the French offensive in Champagne made itself felt in the Argonne. On the 25th, a subsidiary attack, designed to cover the flank of the main attack, was carried out between Servon and Gruerie Wood, over difficult ground, strongly entrenched by the Germans, and flanked by many machine-guns. After carrying the first German lines, the French troops, who had been counter-attacked and decimated by machine-guns on the western edges of the Gruerie Wood, were forced to retire on their original positions. However, this minor operation prevented the enemy from using the Argonne to launch a counter-offensive on the flank of the main attack. On the 27th, they attacked in the Fille-Morte and Bolante sector, doubtless to cover the despatch of reinforcements from the Argonne to Champagne.
