Most of the Allied force in that battle consisted of eager British volunteers. In one of the bloodiest battles in history, the fact that men kept “going over the top” to a coin toss chance of death against entrenched German forces.
To re-take French land, no less.
This a testament to determination and commitment to what they were fighting for. The Allied troops had poor equipment, little experience, dismal leadership, and clearly lacked the strength and resources had by their enemy…yet they kept going in the face of death, persevered, and changed the tide of WW1.
