On the last day of the month French troops in the Champagne made a new attack on both sides of Mont Carnillet, a commanding peak southeast of Mauroy. To the west the French captured several fortified lines of trenches from the heights as far south as Beine. East of the mount General Nivelle's men forced their way up the northern slopes of Mont Haut; and northeast of this position to the approaches of the road from Mauroy and Moronvilliers. This advance widened on the west and deepened the salient driven into the German lines between Prunay and Auberive, rendering exceedingly precarious their hold on ground east of Rheims. There was no important fighting on the British front on April 30, 1917, and General Haig's troops were not ungrateful for the brief respite afforded them. The Germans did not attempt any important attacks owing to a shortage of ammunition and military supplies. From documents found on prisoners the British learned that there was a dearth in all war material and that the supply of new guns to replace those worn out was very limited. During the night General Haig's troops improved their positions between Monchy-le-Preux and the Scarpe River, repulsing a feeble German attack on the new positions. While comparative quiet reigned in the fighting area on the last day of April, 1917, British airmen were active, and in the course of twenty-four hours a number of highly dramatic battles were fought in which the British brought down twenty German aeroplanes and lost fifteen machines themselves. During the night of May 1, 1917, the French consolidated their new positions on the wooded hills east of Rheims. In the course of the following day the Germans delivered two strong attacks against French lines northeast of Mont Haut, but were rolled back by the French barrage fire and machine-gun fire which broke the waves of assault and scattered the attackers. The report for the month of April, 1917, issued by the British War Office stated that in the course of the offensive operations in France 19,343 prisoners had been taken, including 393 officers. In the same period the British had captured 257 guns and howitzers, 227 trench mortars, and 470 machine guns. The French during the same period had captured over 20,000 prisoners. It was estimated that the Germans had 143 divisions in France, but only ninety-nine of these were in the actual line, the rest being held in strategic reserve. During the month of April, 1917, more aeroplanes were lost by the combatants than in any month since the fighting began. A careful compilation from British, French, and German communiques shows a total loss of 717 during this period. The Germans lost 369, the French and Belgians 201, and the British 147. On May 2, 1917, the French in the Champagne began to push their way slowly through the great forest south of Beine, which covers considerable territory from south of Mont Carnillet to La Pompelle Fort, the most easterly fortification of Rheims.
