In the harrowing summer of 1915, valor and horror dance a deadly ballet.

Canadian troops, most unaccustomed the horrors of war, endure trial by fire at the Second Battle of Ypres, confronted with a terrifying new weapon. The yellow-green fog of chlorine gas drifts across the battlefield, its insidious tendrils reaching into trenches, choking and blinding unsuspecting soldiers. Despite heavy casualties, they hold their ground, earning the respect of allies and igniting newfound Canadian nationalism.

Across the Atlantic, the tranquil lives of Americans are shattered as the Lusitania, renowned for its speed and luxury and considered unsinkable, is torpedoed, sinking beneath the waves and taking nearly 1,200 souls — many American citizens — into the depths of the ocean. The tragedy sends shockwaves across the United States, fiercely splitting the nation into camps of passionate war hawks and staunch doves and intensifying pressure on President Woodrow Wilson to abandon his policy of neutrality.

In this riveting continuation of the A Tale of Two Nations: Canada, U.S. and WW1 series, the struggles of ordinary people merge with the tumultuous tides of history. Drawing upon newspaper articles, 1915 offers a fresh perspective on a pivotal year in world history. It brings to life the experiences of ordinary people caught up in extraordinary circumstances, revealing the human cost of war and the enduring power of the human spirit.
