The military organization of the Vigilance Committee, rank and file, numbered nearly 5,000 men. Several of the Executive Committee were alien residents who never became citizens; and in the Committee, serving as troops, as police, and in other lines, were a large number of aliens, not naturalized, many of whom had not acquired sufficient proficiency in the English language to speak it or understand it. The military body comprised four regiments--infantry and artillery--together with battalions of cavalry, pistol companies and guard of citizens. A medical staff was duly organized. The roster, as here given, is copied from a recent publication in the Alta, stated to be authentic.
