Vimy

On Easter Monday 1917 with a blizzard blowing in their faces, the four divisions of the Canadian Corps in France seized and held the best-defended German bastion on the Western Front - the muddy scarp of Vimy Ridge.

The British had failed to take the Ridge, and so had the French who had lost 150,000 men in the attempt.

Yet these magnificent colonial troops did so in a morning at the cost of only 10,000 casualties.
