An original exhibition at the 14-18 Memorial Notre-Dame-de-Lorette brings attention to the often-overlooked role of dogs and cats during World War I. The display features photographs that reveal how these companion animals were present alongside soldiers in the trenches, offering both comfort and practical assistance. The exhibition aims to shed light on the emotional and functional contributions of these animals during the war. Dogs, for example, were used for tasks such as carrying messages, detecting gas attacks, and providing protection, while cats helped control rodent populations in military camps and trenches. Historical records suggest that the presence of these animals was not just a matter of companionship but also had a significant impact on the morale of soldiers. The exhibition includes rare photographs and personal accounts that illustrate how soldiers formed close bonds with their animal companions, often referring to them as family members. By showcasing these images, the exhibition encourages visitors to reconsider the roles of animals in wartime and their lasting legacy. It serves as a reminder of the diverse ways in which animals contributed to the lives of soldiers during one of the most challenging periods in history.
