During World War I, Vimy Ridge was a significant part of the German
defense system. At daybreak on April 09, 1917, four divisions of the
Canadian Corps, aided by the British 5th Division and a great number
of artillery units, started the push up the Ridge. By mid-afternoon most
of the Ridge had been taken. On April 12 the 4th Canadian Division and
the British 24th Division completed taking the northern end.
There were a total of 10,602 casualties of which 3,598 were Canadians.
