French assaults by the German troops were repulsed on the following day when the French carried a wood between Genermont and Ablaincourt, taking prisoner four officers and 110 of other ranks, as well as a number of machine guns. The German aircraft were especially active on this day and the French fought seven engagements. In the Lassigny sector a German machine hit by French guns fell in flames behind its own lines. The clear weather which prevailed during the day of October 16, 1916, tempted British airmen to renewed activity. They bombed successfully railway lines, stations, and factories. During the numerous fights in the air three German machines were destroyed and one was driven to earth, while two kite balloons were forced down in flames. For these successful exploits the British paid somewhat heavily. One of their machines was brought down by German gunfire and six were missing at the end of the day. Heavy bombardments on both sides, trench raids, and counterattacks, which resulted in some successes for the Allied troops, marked the following days. On October 21, 1916, the Germans lost heavily in an attempt to recover Sailly-Saillisel from the French. Three regiments of the Second Bavarian Division recently arrived in this sector were shattered one after the other by French curtain and machine-gun fire. South of the Somme a brilliant little success was achieved by the French north of Chaulnes. Early in the afternoon the French infantry after a heavy bombardment of the enemy lines pushed forward and gained a foothold in the Bois Etoile which was held by troops of Saxony. The Chaulnes garrison attempted to come to the support of the Saxons, but were driven back by the destructive fire from French batteries. Generals Marchand and Ste. Clair Deville, who were wounded in fighting in the Somme region, continued to hold their commands and to direct the action of the French troops under them. Early in the morning of October 21, 1916, German troops in considerable force attacked the Schwaben Redoubt north of Thiepval occupied by the British, and at several points succeeded in entering the trenches. But in a short time the British troops by a vigorous attack drove them out, capturing five officers and seventy-nine of other ranks. A subsequent attack by the British, delivered on a front of some 5,000 yards between Schwaben Redoubt and Le Sars, advanced the British line from 300 to 500 yards. Sixteen officers and over 1,000 German prisoners were taken during this operation, while the British losses were said to be slight. On this same date British aircraft showed great activity, bombing German communications, an important railroad junction, and an ammunition depot, while there were several air duels in which the British destroyed three machines and drove others behind their lines. Two British aeroplanes were not heard from again.
