The comparison between the iconic Brown Bess British musket of the period and the French Charleville (although it was made in other arsenals besides the one at Charleville) might be interesting to discuss. The Royal Arsenals were at Charleville, Saint-Etienne, Maubeuge, and Tulle. New arsenals for arms production were opened at Mutzig, Versailles, Liege, and Turin as well as one for the production of bayonets at Klingenthal.
The Brown Bess, or more correctly, the Short Land Pattern and Long Land Pattern Muskets, were excellent weapons of .75 caliber that were used in various models from their inception. The Short Land Pattern became the standard during the War of the Revolution in America and the Long Land Pattern went out of production and those already made were no longer issued. The round, or ball, weighed slightly over one ounce.
French military muskets were generally known by their year of manufacture and not the place where they were manufactured. The term 'Charleville' came into usage in the United States as many of them that were sent to the Continental Army were manufactured there. The name more or less stuck with them. The French musket was of .69 caliber-eighteen French balls equaled one pound.
The last Royal Army model of musket was that of 1777. This model was improved and simplified in the System of the Year Nine (1800-1801) and was again improved in the Year Thirteen (1804-1805).
Both muskets were excellent weapons and gave good service during the wars. The Continental Army during the War of the Revolution began with the Brown Bess and after shipments of French muskets were received, the troops preferred the French model even though it fired a smaller ball. The 'Charleville' became the issue musket of the Continental Army. The excellent 1795 model Springfield musket was modeled on, if not a direct copy, of the French model 1777 musket. It saw service as the issue musket during the War of 1812.
The study of French and British small arms of the period also includes fusils, carbines, mousquetons, dragoon muskets, pistols and rifled long arms as well as rifled pistols.
