query: How many casualties were there during the German attack on Vimy Ridge, 21 May 1916 ?
passage: German attack on Vimy Ridge, 21 May 1916
The Germans attacked on 21 May and were able to consolidate their objectives, before the British could conduct counter-attacks powerful enough to recapture the ground. In the attack and its aftermath the Germans suffered 1,344 casualties against the 2,475 British losses. A British plan to recapture the front positions and take the German side of the ridge was cancelled, because of the demand for men and equipment of the forthcoming Battle of the Somme, the attack on the Gommecourt Salient taking priority. British planning continued and became the basis for the much larger attack by the Canadian Corps at the Battle of Vimy Ridge (9–12 April 1917).
passage: 10th Battalion (Canadians), CEF
Vimy, 1917 — Intended as a diversion to draw attention away from French actions farther south, and often serving only as a footnote to the less successful overall Battle of Arras in 1917 waged by the British armies, Vimy was the greatest victory of the war for the Canadian Corps, which by 1917 numbered four divisions. In a dramatic assault on Easter Monday, the 9th of April, and representing the best in Canadian tactical ingenuity, military engineering, and technical innovation, the Canadians seized most of this dominating feature in a few short hours, and finally clearing the entire ridge in three days. The British and French had been unable to clear these heights since the Germans first seized them in 1914, and had lost more men in the process of trying than the Canadians as a whole started out with on 9 April. The 10th Battalion had its own role to play in this great drama, and reached all its objectives on time, at the cost of 374 casualties.
