The French communiqué of September 24 recorded Lieutenant Guynemer’s seventeenth and eighteenth victories over German aircraft on the Somme front. As a matter of fact, Lieutenant Guynemer destroyed three aeroplanes on that day while extricating a brother aviator from the clutches of five enemy craft. Two of the latter took flight, and three remained. At 11.22 the first German was shot down. The second followed thirty seconds later, and the third, already in full flight, was destroyed at 11.25. A summing up of the French communiqués issued between July 1 and September 25 showed that 250 enemy aeroplanes had been destroyed or brought down out of control within their own lines; twenty-two observation balloons had been burned; 142 objectives within the territory occupied by the Germans had been hit; and 5,426 bombs had been dropped. Such figures bear eloquent testimony to the air services of our gallant Allies. Further good work was done in October of the same year. On the second day of the month Sergeant Sauvage brought down his fifth German machine. A few days later Adjutant-Pilot Baron and Adjutant Chazard bombarded at Stuttgart the Bosch magneto factory. Dense smoke was seen rising from this factory as the result of the bombardment. Stuttgart, the capital of Würtemberg, is 100 miles from the nearest point on the French frontier. The return journey, therefore, involved a flight of at least 200 miles. On the tenth day of the same month, in addition to numerous surveillance, reconnaissance, and range-regulating flights, French aeroplanes fought fifteen engagements in the Verdun region, fourteen south of the Somme, and forty-four north of that river. In the course of the latter engagements four enemy machines were brought down, one by Adjutant Dorme, who thus brought down his thirteenth machine. Six other enemy machines were seriously hit and fell into the German lines. It is noteworthy, as showing the unity of action between the French and British Air Services, that on October 13 a Franco-British squadron of forty aeroplanes bombarded the Mauser Works at Oberndorf on the Neckar. Four thousand three hundred and forty kilogrammes (over four tons) weight of projectiles were dropped, and their attainment of the objectives aimed at was noted. Six German aeroplanes were brought down in the course of fights into which they entered to defend their factories. The raid on the Mauser factory was one of a series of attacks on important works in Germany carried out by Allied aviators. During the previous three weeks military establishments, blast furnaces, and factories had been raided.
