On 9 April 1917, British Empire forces launched a major offensive around Arras. In the south some units advanced more than five kilometres into German-held territory, while to the north Canadian troops captured Vimy Ridge. During the following weeks, fierce German resistance and poor weather prevented any further significant advances. By the end of the offensive on 16 May, some 300,000 men on both sides were wounded, missing or dead.
