The Vendeans revolted against the Revolutionary government in 1793. They resented the harsh oppression imposed on the Catholic Church by the provisions of the Civil Constitution of the Clergy act (1790) and broke into open revolt after the Revolutionary government's imposition of military conscription. A massacre of Republicans at Machecoul in March was followed by guerrilla warfare, led at the outset by peasants who were chosen in each locale, and cost more than 240,000 lives before it ended in 1796 (190,000 Vendeans who were republicans or royalists and 50,000 non-Vendean republican soldiers; according to the Jacques Hussenet and Centre Vendéen de Recherche Historique's book "Détruisez la Vendée"). The Revolt in the Vendée must not be confused with the revolt of the Chouans, which took place at the same time in Maine and Brittany. In 1804, Napoleon I chose La Roche-sur-Yon to be the capital of the department. At the time, most of La Roche had been eradicated in the Vendée Revolt (1793–96); the renamed Napoléonville was laid out and a fresh population of soldiers and civil servants was brought in. Napoléonville had a square-grid street network and was designed to accommodate 15,000 people.
