In the summer of 1916, the Canadian Corps faced a brutal test of endurance and resolve during the battles of Mount Sorrel and Hill 70. As the German army launched a massive offensive to seize the high ground protecting the Belgian city of Ypres, thousands of Canadian soldiers, many of whom were volunteers with little combat experience, were thrust into a harrowing struggle for survival. Through the mud, the relentless shelling, and the devastating use of flamethrowers, these men held their ground, forging a legacy of courage and sacrifice that would define the Canadian contribution to the First World War.
