On Tuesday I got two postcards: one from Canada and one from Thailand.
The card from Canada shows a graffiti carved into the stone wall of an underground tunnel near Vimy Ridge. Vimy Ridge is known for its underground tunnels. They were used during World War I as protection for Canadian soldiers and to place mines beneath the German trenches. In total there are about ten miles of tunnels, which were carved by around 1000 miners working as silent as possible to not be heard by the Germans. In the tunnels there are kitchens and bedrooms and they were supplied with water and fresh air.
The Battle of Vimy Ridge was fought in 1917 between the German Empire and the British Empire and is a part of the Battle of Arras. It was the first battle in which the four divisions of Canadian Expeditionary Force fought together. It ended with a victory of the British Empire.
With a related stamp:
Centenary of the Battle of Vimy Ridge (from set of two) (issued 08-04-2017)
It is a joint issue with France.
Thank You very much Kelly!
