Charles Lanrezac (31 July 1852 – 18 January 1925) was a French general, formerly a distinguished staff college lecturer, who commanded the French Fifth Army at the outbreak of the First World War. His army, originally intended to strike the Germans on their western flank, faced the brunt of the German march, stronger and further west than anticipated, through Belgium at the Battle of Charleroi. He was frustrated by the reluctance of his superior, General Joseph Joffre, who was initially preoccupied by French attacks into Lorraine and the Ardennes, to appreciate the danger of the German march through Belgium. Forced to retreat, at Joffre's insistence he made a successful counterattack at the Battle of Guise, but his apparent reluctance to counterattack led him to be relieved of command prior to the Battle of the Marne. He is particularly remembered in British writing as his army fought on the right of the small British Expeditionary Force, with whose commander-in-chief, Sir John French, he had a poor relationship. Early life Lanrezac was a Marquis, but did not use his title. He was of swarthy appearance (he had a “a dark creole face” in Barbara Tuchman's description) and was a native of Guadeloupe. Lanrezac attended the military school at Saint-Cyr in 1869 but when the Franco-Prussian War started in 1870, he was sent to fight as a lieutenant. He fought with the Armée de la Loire at Coulmiers and in the campaign around Orléans. In January 1871 he was transferred to the Armée de l'Est and following the failure of its campaign, he was interned in Switzerland. By 1876 he had been promoted to captain. He graduated from the École Militaire in 1879. During the following years Lanrezac served in various staff functions in the 113th Infantry Regiment and on a brigade staff in Tunisia. Lanrezac was promoted to colonel in 1902 and given command of the 119th Infantry Regiment. He became a brigadier-general in June 1906, commanding the 43rd Infantry Brigade stationed in Vannes. He served under Joffre with 6th Infantry Division and became Joffre's protégé. After this brigade command he was made a professor at the École Militaire. He was a brilliant lecturer, but caustic and ill-tempered. He became known as “the lion of the French Army”. Lanrezac was an opponent of Foch’s theories of offensive a l’outrance, writing that “if every subordinate commander has the right to ram home an
