CANADIANS AT ARRAS—NIVELLE IN COMMAND In the afternoon of December 20, 1916, Canadian troops made an important raid on German trenches north of Arras on a front of 400 yards and succeeded in putting out of action, temporarily at least, an entire battalion of German infantry. A British officer engaged in the raid thus describes the struggle after the German line was penetrated: "As we entered the trenches many Germans broke from the dugouts. All who did were subsequently well cared for. Each of our men was given definite instructions for his precise task and a map of the enemy's trenches, which proved absolutely correct. "Each man knew every detail of the proposed operation. They were delighted at this and entered the fight with great cheers. When they came out two hours later they were singing and as happy as schoolboys on a holiday. "The neatness and dispatch with which the raid was carried out were unique. The artillery cooperation of the British guns was perfection. Beautifully placed curtains of fire prepared our advance, and creeping forward protected us as they proceeded to demolish absolutely the enemy trenches and dugouts. The program had given the men an hour and a half for their work, but the clean-up was accomplished in an hour and ten minutes, when the raiders signaled that they were ready to return to their own trenches." During the night of December 19, 1916, British troops made a successful raid on German lines in the neighborhood of Gommecourt, where after doing considerable damage to the defensive works they retired without any casualties. Early in the morning of the following day the British made another successful raid on German trenches north of Arras, where they captured a number of prisoners. On the same date, December 19, 1916, a British contingent encountered a hostile patrol north of Neuve Chapelle. After a brief, sharp fight the leader of the patrol was killed and his men surrendered. German official reports of this date stated that, west of Villers-Carbonnel, Grenadiers of the Guard and East Prussian Musketeers forced their way into a strong British position that had been destroyed by effective fire, and after blowing up dugouts retired to their own lines, bringing away with them four officers and twenty-six men as prisoners. The Germans claimed that during various air engagements about this time along the Somme they destroyed six hostile aircraft. During the night of December 20, 1916, a strong German raiding party attacked the British line opposite Lens, but only a few succeeded in penetrating the trenches. After a short struggle these were ejected by the British troops and the raiding party was driven off. Southwest of ArmentiÈres a British raiding party entered German trenches and made some prisoners. On December 21, 1916, the French Government made public the official order summoning General Nivelle to the command of the armies of the north and northeast and signed by General Joffre.
