Canadian Corps Launches Assault on Vimy Ridge

Summary

In the midst of World War I's grinding stalemate on the Western Front, Allied commanders planned a major offensive near Arras, France, to relieve pressure elsewhere. The Canadian Corps, under British command but operating as a distinct national formation, received the critical task of capturing the heavily fortified Vimy Ridge, which had resisted previous French and British attacks. On April 9, 1917, after weeks of artillery preparation and innovative infantry tactics including creeping barrages, the Canadians advanced across no-man's-land under snow and sleet. They secured most objectives within hours despite fierce German resistance and high casualties. The immediate result was a rare clear victory that boosted Allied morale and demonstrated Canadian military effectiveness.
