In the afternoon of the following day, October 22, 1916, the British right wing advanced east of Gueudecourt and Les Boeufs and captured 1,000 yards of German trenches. On the same day British airmen bombed two railway stations behind the enemy's lines, hitting a train and working great damage to buildings and rolling stock. The British airmen in a series of engagements brought down seven German machines, damaging others and forcing them to descend. At the close of the day eight British machines were missing. CHAPTER IX FRENCH RETAKE DOUAUMONT On October 24, 1916, on the Verdun front a great victory was won by the French in the capture of Fort Douaumont. This stronghold, which had been termed by the Germans "the main pillar of the Verdun defenses," had been captured by the Brandenburgers in the last week of February, 1916. The French lost the fort, but they clung desperately to the approaches, which for weeks were the scenes of bloody struggles. The fort was retaken by the Allied troops on May 22, 1916, but after two days of furious bombardment and the attacks of fresh German troops they were driven from the place. From that time until the French recaptured it on October 24, 1916, it had remained in German possession. Shortly before noon of the last date the French launched their attack on the right bank of the Meuse after an intense artillery preparation. The German line, attacked on a front of about four and a half miles, was broken through everywhere to a depth which attained at the middle a distance of two miles. General Nivelle had intrusted the plans for the recapture of Fort Douaumont to General Mangin. Artillery preparation began on October 21, 1916, when the air was clear and favored observation by captive balloons and aeroplanes. For two days the fort and its approaches were subjected to an almost continuous bombardment of French guns. On October 23, 1916, the explosion of a bomb started a fire in Fort Douaumont. The shelters covering the quarries of Haudromont were destroyed and also the battery at Damloup, while the ravines were blown to pieces. Owing to the wide extent of the French attacks the Germans seemed to have been in doubt as to the point from which the main assault would be launched. Gradually the French "felt out" the positions of the 130 German batteries, a great number of which they destroyed.
