Many American citizens flocked to join the Allied war effort against Germany during the First World War before their mother country eventually declared war in 1917. William Yorke Stevenson was one of their number, volunteering for service with the French Ambulance corps or Section Sanitaire. Never war from the frontlines in rather ramshackle old vehicles [the flivver of the title is a slang term for a run-down truck], these men risked their lives to evacuate and treat the wounded. The Author recounts his experiences of 1915-1917 based on his dairy of the period. It provides a day-by-day account of the medical services behind the lines during some of the heaviest French fighting of the war during the battle of the Somme. Illustrated throughout with the Author's own photos of the period, including his comrades, conditions and the battle damage of the towns and villages amongst which he worked and lived.
