Canada goes to war
In 1914, Canada's external affairs were governed by the United Kingdom. This meant that once Britain declared war, Canada automatically followed. The First World War opened with great enthusiasm and patriotism on the part of many Canadians, with tens of thousands rushing to join the military in the first months of the conflict so they would not miss the action. They need not have worried as the war would grind on for more than four years, killing as many as ten million combatants in fighting that would be revolutionized by high-explosive shells, powerful machine guns, poison gas, submarines and war planes.
After the initial German advances of the war, the battle along the Western Front quickly turned into a stalemate of trench fighting, with the front-line zigzagging for nearly 1,000 kilometres from the coast of Belgium to the border of Switzerland.
