The strip follows Charley's life in the trenches and his experiences during the war. Colquhoun put a meticulous level of research into the already well-researched scripts which Mills provided. The strip rarely flinched from providing an extremely frank portrayal of the horrors of war, so much so that in some later reprintings some of the artwork was censored. Mills added a political slant in the strip not seen in British war comics and avoided the standard heroics common in war comics generally.
