Bombarding aircraft showed great activity during the night of the fourteenth. A squadron of ten machines dropped eighty-five bombs on the railway stations and the lines at Tergnier and Chauny, and on the station and the huts at Guiscard. Many of the bombs found their mark. A big fire was observed at Tergnier and the beginning of an outbreak at Guiscard. Another French squadron dropped forty bombs on the barracks at Stenay, where several fires were observed, and forty on the works at Rombach. One pilot got as far as Dillingen, in the Valley of the Saar, where he dropped eight bombs on a large workshop, causing a fire. During the same night the blast furnaces at Rombach received ten bombs, and the railway from Metz to Pont-a-Mousson four, which caused considerable damage. Later, it was learnt that besides the nine German aeroplanes brought down on the French front on the fifteenth, six other enemy machines were forced to come down in a damaged condition in their own lines after fights with French pilots. On September 17 it was confirmed that an enemy machine, which was attacked by machine-gun fire by Adjutant Lenoir, fell north of Douaumont. This was the eighth brought down by this pilot. It was also confirmed that Adjutant Dorme defeated his tenth enemy machine, which fell on September 15 between Erie and Ennemain. At a later date (September 23), French aviators fought fifty-six engagements on the Somme front, in the course of which four enemy machines were brought down, while four others were seen to fall in a damaged condition. During these fights Adjutant Dorme brought down his eleventh German machine (in the neighbourhood of Goyencourt), Lieutenant Deullin his seventh (south of Doingt), Adjutant Tarascon his sixth (south-west of Hergny). The fourth German machine reported as having been brought down fell south-west of Rocquigny. On the same day, in the region of Verdun, Adjutant Lenoir attacked a German machine at close quarters and brought it down in its lines north of Douaumont. This was the tenth machine brought down by Adjutant Lenoir. At a later date, the French pilot, Adjutant Baron, accompanied by a bombardier, left his aviation camp at 7.15 p.m. and reached Ludwigshafen, in the Palatinate (about 100 miles from the nearest point of the French border), where three bombs were dropped on military establishments. Continuing their route, the aviators dropped three more bombs on an important factory at Mannheim (ten miles farther east), on the right bank of the Rhine, where a vast fire and several explosions were noticed. The aviators returned safely at 12.50 a.m.
