Therefore, he created a Municipal Guard of Paris, a full-time gendarmerie which was strongly militarized. However, he did not abolish the National Guard but was content to partially disarm it. He kept the force in reserve and mobilised it for the defence of French territory in 1809 and 1814. In Paris during this period the National Guard comprised twelve thousand bourgeois property owners, serving part-time and equipped at their own expense, whose prime function was to guard public buildings on a roster basis. Between 1811 and 1812 the National Guard was organized in "cohorts" to distinguish it from the regular army, and for home defence only. By a skilful appeal to patriotism, and judicious pressure applied through the prefects, it became a useful reservoir of half-trained men for new battalions of the active army. After the disastrous campaign in Russia in 1812, dozens of National Guard cohorts were called up for field duty the next year; four cohorts being combined to form one line infantry regiment. The 135ème to 156ème Régiments d'Infanterie de Ligne were thus formed. Many of these fought in the campaigns in Germany in 1813 and the invasion of north-east France by Coalition forces in 1814. Existing National Guard units, such as those of Paris, were deployed as defence corps in their areas of recruitment. Mass conscription was extended to age groups previously exempt from military service, to provide more manpower for the expanded National Guard. Students and volunteers from gamekeepers and other professional groups formed separate units within the National Guard. Clothing and equipment were often in short supply and even the Paris National Guard was obliged to provide pikes as substitute weapons for some of its new recruits. These field and regional units were disbanded in 1814 after the abdication of Napoleon I. Six thousand national guardsmen took part in the Battle of Paris in 1814. Following the occupation of Paris by the allied armies, the National Guard was expanded to 35,000 men and became the primary force for maintaining order within the city. The Restoration Under the Restoration in 1814, the National Guard was maintained by Louis XVIII. Initially, the Guard, purged of its Napoleonic leadership, maintained good relations with the restored monarchy. The future Charles X served as its Colonel-General, reviewed the force regularly and intervened to veto its proposed disbandment on the grounds of economy by the Conseil Municipal of Paris. However,
