The Tharaud brothers became unique eyewitnesses to history when summoned in 1917 from the Western Front to Morocco by the Resident-General of the French Protectorate there, Lyautey. The colonial conquest of Morocco had been put on hold after the French army was summoned home in 1914. But in a delicate balancing act, Lyautey kept the peace by establishing a working alliance with some of the most powerful of the tribal lords of Morocco. It was part of a coherent policy to avoid the mistakes in Algeria and preserve Morocco's historical architecture, faith and culture intact for future generations.
