Felix Cullen was born in 1889, in Renfrew, Ontario. A steelworker by trade, he enrolled in the Canadian Expeditionary Force in Toronto, on November 12, 1914. On May 13, 1915, he set sail for Europe and, a few weeks later found himself in France, in the trenches, under enemy fire. Felix Cullen fought at various places on the European Front, including St. Éloi and the Somme, where some of the war's most deadly battles took place.

From the first months of the war, trench warfare predominated. The military authorities adopted an offensive strategy, stressing control over the territory, maintained by building and capturing trenches. Life in the trenches was difficult, with much labourious and tedious work to be performed, interspersed with terrifying episodes that had the potential of killing thousands of soldiers in just a few hours. The trenches also had a devastating effect on the European countryside, and left their mark there for a long time to come.
