Over the doorway leading to the Memorial Chamber in the Peace Tower, this tympanum pays tribute to animals that served during the war – reindeer, pack mules, carrier pigeons, horses, dogs, canaries and mice. The inscription reads:
The tunnellers’ friends, the humble beasts that served and died.
Les amis des sapeurs ces humbles bêtes de somme qui moururent pour la cause.
The tympanum was designed by John A. Pearson and carved in 1927 by Cléophas Soucy in Indiana limestone.
