In the Ypres sector during the first four days of March the fighting was confined to the usual round of violent artillery duels, mine springing, hand grenade skirmishing, intermittent hand-to-hand attacks and effective aircraft raids. On March 1, 1916, twenty British aircraft set out seeking as their objective the important German lines of communication and advanced bases east and north of Lille. Considerable damage was inflicted with high explosive bombs. One British aeroplane failed to return. From all parts thrilling, tragic and heroic aerial exploits are recorded. While cruising over the Beanon-Jussy road a German Fokker observed a rapidly moving enemy transport. Reversing his course, the pilot floated over the procession and dropped bombs. The motor lorries stopped immediately, when the aeroplane dropped toward the earth, attacked the transport at close range and got away again in safety. On the same day also a French biplane equipped with double motors encountered an enemy plane near Cernay, in the valley of the Thur, and brought it down a shattered mass of flame. North of Soissons, near the village of Vezaponin, a French machine was shot down into the German lines; another French aero was struck by German antiaircraft guns; with a marvelous dive and series of loops it crashed to earth. Both pilot and observer were buried with their machine. During the evening of March 1, 1916, the German infantry, after a furious cannonading north of the Somme, delivered a sharp assault on a line of British trenches, but were held back by machine-gun fire. Along the Ypres sector the same night violent gunfire took place on both sides with apparently small effect or damage. In a previous volume it was mentioned that the Germans had once more recaptured the "international trench" on February 14, 1916. For a fortnight the British artillery constantly held the position under fire and prevented the consolidation of the ground. At 4.30 a. m. the British infantry suddenly emerged from their trenches. The grenadiers dashed ahead, smothering the surprised Germans with bombs. The general disorder was increased by the fact that the trench parties were just being relieved. In a few minutes the lost ground was recovered, the German line dangerously pushed in and 254 prisoners, including five officers, fell to the British. At midday the Germans bombarded the line with fifty batteries for four hours. Then waves of assaulting columns were let loose against the British. The latter noticed that the front line of infantry hurled their bombs several yards _behind_ the British trenches and rushed forward with hands up. Immediately a hurricane of shells from their own guns burst among the German infantry. The survivors flung themselves on the ground and crawled into the British trenches for protection. This action was the more significant in that the men who thus surrendered were all very young and belonged to a regiment which, until then, had fought with
