On July 1st, 1913, four very different men are leading four very different lives. Exactly three years later, it is just after seven in the morning, and there are a few seconds of peace as the guns on the Somme fall silent and larks soar across the battlefield, singing as they fly over the trenches. What follows is a day of catastrophe in which Allied casualties number almost one hundred thousand. A horror that would have been unimaginable in pre-war Europe and England becomes a day of reckoning , where for Frank, Benedict, Jean-Baptiste, and Harry, their lives will change forever.
