In January 1914, the French Army had 47 divisions, composed of 777,000 French soldiers and 47,000 colonial troops. Another 2.9 million men were mobilized in the summer of 1914, and heavy losses on the Western Front forced France to conscript men up to the age of 45. At the end of the war the French had called up 8,317,000 men, including 475,000 colonial troops, and suffered over 4.2 million casualties, with 1.3 million dead.
