Three generations of Blackwoods have served the Royal Marines with distinction. Now it is the turn of young Jonathan Blackwood to take up arms and fight in his country’s most recent war, a conflict that has already embroiled all of Europe: World War 1. In 1915, he fights from the sea, supported by the Royal Navy in the battlefields of the Dardanelles and Gallipoli. Two years later in Flanders, Blackwood finds that Hell can get worse as he and his men are fighting on the horrifying Western Front.
