The story, which was first published in 1915, centers on Harry Sandwith, the protagonist, as he enlists in the recently established British Army, and is set against the backdrop of World War I. The story starts when Harry enlists in the military and joins the New Army, a group established in reaction to the worsening fighting. The narrative follows Harry as he transitions from a citizen to a soldier, describing his training, his fellow soldiers' companionship, and the difficulties he encounters in combat. The work also highlights the collaboration between French and British forces during the conflict, as the title would imply. The protagonists participate in a range of military operations and encounter the hardships of trench warfare. A major component of the story is the friendship and struggles they share. Adventure story author Herbert Strang blends historical realism with a spirit of adventure and patriotism in "Fighting with French." The book's depiction of the valour and tenacity of troops during a turbulent historical period is meant to enthrall young readers.
