Napoleon's line infantry was founded upon that of the Ancien R gime. A total re-organisation began on 1 January 1791 with the abolition of the old regimental titles, and over the next two years an increasing number of conscript and volunteer battalions were formed. Their quality varied from the proficiency of the early National Guard regiments to the untrained and ill-equipped rabble of the lev e. To combine the discipline and steadiness of the regular army with the revolutionary fervour of the new army, the Amalgame was decreed on 21 February; by this measure each regular battalion became the nucleus of a new Demi-Brigade.
