Squadrons of tanks were active during the advance, while the French aviators distinguished themselves aloft by showering machine-gun bullets upon the German infantry from an altitude of not more than 100 yards. The capture of the Malmaison plateau by the French was of the first importance, for it was the key of the ridge between the Aisne and Ailette Valleys; an unrivaled observation point commanding the Laon plain. In gaining it the French really "turned" the Chemin-des-Dames Ridge, to the northern slopes of which the Germans had clung so long. [Illustration: The taking of Malmaison and Chemin-des-Dames.] On October 25, 1917, the French forces on the Aisne resumed the offensive, a general push being made beyond the positions reached in the last advance, extending to the Oise-Aisne Canal. The village and forest of Pinon were captured, and the hamlet of Pargny-Filain. South of Filain the fortified farms of St. Martin and La Chapelle Ste. Berthe were occupied. On the front between Mont des Singes (Monkey Mountain) and Chavignon French troops made further progress and reached Rohay Farm. The Germans counterattacked at various points on the fighting front, but were unable to make any progress. The French held securely all the new positions gained during the advance, and the number of German prisoners had now increased to over 12,000, of whom 200 were officers. Among the spoils captured were 120 guns, many of the heaviest description. On the British fronts in France and Flanders there were no important actions. During the night of October 24, 1917, British aviators made a successful raid on Saarbrücken. West of this place naval machines dropped three and one-half tons of explosives on the Burbach works, and other factories as well as railway communications were attacked with good results, many explosions being noted. A train proceeding from Saarbrücken received a direct hit from a big bomb and was destroyed. On October 26, 1917, the British and French armies north, northeast, and east of Ypres renewed the offensive. The attacks began in a cold rain that had been falling for several hours. Haig's troops first advanced from a point near St. Janshoek westward through the southern fringe of Houthulst Forest to the neighborhood of Nieuemolen. The other assault was on both sides of the Ypres-Menin highway along the Gheluvelt Ridge toward the town of that name. Bellevue Spur, west of Passchendaele, was crowded with machine guns, but the British entered it an hour after the attack began. The Germans concentrated a heavy artillery fire on Bellevue, while the British were fighting arduously with rifle, bomb, and bayonet among the concrete fortifications. Through Wolf Copse, near Bellevue, that had been the scene of many sanguinary struggles, the British swept on, gaining Polderhoek Château, north of Gheluvelt, where there was close, intense fighting before the Germans were forced to yield.
