Owing to the weather conditions, little progress was made by the Allied forces on September 19, 1916. Raids were successful, however, on enemy trenches northeast of Bethune, and the French made some advance and took prisoners east of Berny. The Germans made five spirited attacks against the French front in Champagne where the Russian detachments were posted, all of which were repulsed with heavy losses by the guns and machine guns. From 9 in the morning until nightfall of the following day the Germans continued their assaults on the French lines, but only here and there did they make even temporary progress. On Thursday, September 21, 1916, the British line in the west was again advanced. A section of the German front about a mile long was attacked between Martinpuich and Flers. Two lines of German trenches were captured in this push. Meanwhile the French continued to develop their hemming in of Combles, nibbling their way forward, taking prisoners and guns, a slow but determined advance that the Germans could not restrain. British guns displayed great activity on Friday, September 22, 1916, when they destroyed ten hostile gun pits, damaged severely fourteen others, and blew up five ammunition pits. About the same time fifty aeroplanes raided an important railroad junction, destroyed several ammunition trains, and caused violent explosions and conflagrations. September 25, 1916, was a notable day in the history of the Allied advance in the west, when French and British forces again assumed the offensive. The German positions were stormed on a front of about six miles between Combles and Martinpuich to a depth of more than a mile. The strongly fortified villages of Les Boeufs and Morval with several lines of trenches were captured. Morval, standing on a height north of Combles, with its subterranean quarries and maze of wire entanglements, constituted a formidable citadel of defense. By the capture of these villages German communication with Combles was cut off. The British took a large number of prisoners and immense quantities of war material. About noon of the same date the French attacked the German positions between Combles and Rancourt and the defenses from the latter village to the Somme. Rancourt was taken after a sharp struggle, and the French lines were advanced to the northeast of Combles as far as the southern outskirts of Fregicourt. East of the Bethune road the French positions were extended for half a mile, while farther south several systems of German trenches were captured in the vicinity of the Cabal du Nord. On the second day of the Allied offensive the French and British continued their successful advance. Combles, which the Allied troops had been closing in on for some days, was captured. Here an enormous quantity of booty, munitions, and supplies which the Germans had stored away in the subterranean regions of the place fell to the victors.
