Blue- A British deserter from the French Foreign Legion, 'Blue' fled to England after surviving the hellish Battle of Verdun in 1916 in which most of his fellow Legionaries were slaughtered. Charley reluctantly helps Blue to avoid capture whilst in Britain and later encounters him again during the infamous Etaples Mutiny in 1917. Despite his misgivings over Blue's desertion, Charley cannot help but feel a kinship with him due to their common resentment of the military hierarchy and Charley's realisation that, with less fortunate circumstances, he could have easily ended up the same way.
