The Battle of Vimy Ridge took place in the Nord-Pas-de-Calais region in France in 1917. The battle was part of the Battle of Arras during World War I, and it pitted four Canadian Corps divisions against the German Sixth Army.
The offensive began on Easter Sunday in April 1917 with the Canadian Corps engaging the Germans during a sleet storm. The Canadian victory was said to be a result of creeping barrage and excellent artillery preparation as well as the training and execution of the infantry. The defeat of Germany was blamed on sleet used as a cover, poor defensive plans on the behalf of Germany and the Canadians use of underground tunnels and caves during the engagement.
Also working for the Canadian's side was their numbers; they outnumbered the Germans by a ration of more than three to one, with Canada having 35,000 men to Germany's mere 10,000. Canada also deployed 1,130 guns for the fight.
Roughly 10,500 Canadian casualties resulted from the battle, with nearly all of the strength of the German forces lost as well as 4,000 prisoners. The skirmish lasted for three days and was considered a swift victory. It was the first time that the Allies' four Canadian divisions attacked in unison.
