Battle of St. Julien

The battle of St. Julien, Belgium (April-May 1915), was the first major poisoned gas attack on allied forces. Canadian troops held off a strong German advance but at a significant cost.

Agar Adamson fought at St. Julien and was wounded at Frezenberg (May 1915). 

Recruitment posters and tags created after the attack were intended to inspire those back home to recall and avenge the great loss of Canadian soldiers who fell during the battle.
