In the evening of July 18, 1917, the Germans attacked the French lines south of St. Quentin over a front of about half a mile. They succeeded in penetrating the first line, and held it for a brief period, when they were driven out. A few hours later the Germans made another strong attack over a front of about four miles, their objective being the same--the hillock known as Moulin-sous-Toutvent. This attack was broken up by the French artillery and machine-gun fire. Throughout the day of July 19, 1917, French and German artillery were active along the whole French front, but beyond inflicting some casualties for which they paid heavily the Germans gained no advantage. A general assault was launched by the Germans with important forces during the night of July 19, 1917, on the line along the plateau between Craonne and Vauclerc. Over the whole extent of the front there was hand-to-hand fighting, but everywhere the French succeeded in holding their positions. An energetic counterattack made between the Californie and Casemates Plateaus enabled the French to regain a trench line which the Germans had penetrated and held since the previous day. Fighting continued in the Hill 304 region, and in the Champagne, but the Germans failed to make any progress. [Illustration: The Somme Battle Front, August 1, 1917.] During these days of intense fighting on the French front the British had not been marking time, but they had far less to contend against than their valorous allies. The French had to bear the brunt of German fury throughout the week. The whole French line from Verdun to St. Quentin in this period had been subjected to almost continuous attacks. At the cost of enormous losses that had not been exceeded during the war, save at Verdun in the previous year, the Germans had only gained a slight advance on a front of 2,000 feet, at the foot of the slope leading to the Chemin-des-Dames between Vauclerc and Craonne. The French now held all the important heights of the Aisne which Hindenburg had declared were impregnable. The German High Command had given orders that the French positions on the heights must be captured at all hazards. Throughout the night of July 21, 1917, the high plateaus north of Craonne were shelled by German guns of the heaviest caliber. An attack was made at daybreak from Hurtebise to the east of Craonne. The two plateaus to the north, called the Casemates and Californie positions, are three-cornered in shape, projecting toward the north and joined by a narrow saddle. The approach to this is not so abrupt from the north as that to the plateaus themselves. The French artillery fire broke up the attack between Hurtebise and the Casemates Plateau before it could develop.
