part lodged at the Villa Poiret about a hundred yards away. Joffre held the conference of Chantilly from 6 to 8 December 1915 to makes battle plans with his Allied counterparts and to coordinate military offensives for 1916. General Headquarters moved to Beauvais in December 1916, and Chantilly became home to hospitals for soldiers wounded on the front, one in the hôtel Lovenjou, the other in the Egler Pavilion. One of the three camouflage workshops of the French 1st Engineers Regiment opened in 1917 in custom-built barracks on the petite pelouse near the racetrack. Up to 1200 women were hired, as well as 200 German prisoners of war and 200 workers from Annam in French Indo-China (then a French protectorate). They painted canvases which the army used to mask artillery and troop movements from view. The town grew in 1928 with the annexation of the Bois Saint-Denis from Gouvieux. In 1930 a monument was put up to Maréchal Joffre on the avenue which now bears his name. World War II The Wehrmacht entered the city on 13 September 1940, and occupied it. They used the Great Stables as a veterinary hospital for the horses they brought in from Germany, by some estimates the city was home to as many as 400 German horses during the war. The military command took over the hôtel du Grand Condé. Following the assassination of a collaborator, the parish priest, Abbot Charpentier, who authored a 1943 anti-Nazi sermon, was arrested along with several French Resistance fighters he had supported. He was deported to the Mauthausen camp, where he died 7 August 1944. The viaduct at La Canardière was bombed by Allied forces on 30 May 1944, and the town was liberated by American tanks on 31 August 1944. The American 8th Air Force in turn installed itself at the hôtel du Grand Condé. Post-war Chantilly Since the war, the city has developed new neighborhoods on the north side of town. Some hotels and villas at the center of town became residences; some stables were torn down to allow housing to be built. As this new housing was built, a new population moved in who mostly work in the Paris area, while the town lost almost all of its remaining industrial base when the Guilleminot factories shut down in 1992.
