Military Terminology

Over 150 years separate us from the Civil War. Some words had different meanings then; some words are not in our current lexicon; some words mean different things in military parlance than in the civilian world. "A Complete Dictionary of Military Terms and Science" Louis Le Grand's The Military Handbook & Soldier's Manual of Information, published in 1861, provides the initial input for this listing. Other terms will be added as documented 19th century meanings can be found. As always, contributions always welcomed

Each State has its separate military organization, by which all citizens liable to bear arms are enrolled, and mustered into divisions, brigades, regiments, companies, etc. In most States, even the commissioned general officers are elective, each division electing its commanding officers, who are commissioned by the Governor on their certificates of election. The Governor nominates the adjutant-general, quartermaster-general, inspectors, etc., as well as his own staff. The militia, in time of peace, are only required to attend the various annual or semi-annual musters ordered by State laws. In event of war, the general Government issued its proclamation announcing war and its causes, when the Secretary of War makes his requisition on the Governors of the States for the needed troops. The Governors then accept volunteers for their quota, and send them forward at command of the War Department. If volunteers do not offer in sufficient numbers, then the requisite force is obtained by drafting - The militia are mustered, and the white and black bean, drawn from a box, indicates the men.

Musketry Range - Effective musketry range of fire is when delivered against infantry from 200 to 250 yards, and against cavalry from 30 to 60 yards. The reasons that the range of a cannon or a musket-ball is limited when fired from rifled artillery and musketry, or from the smooth-bored cannon and musket, are, that its momentum gradually diminishes in its range or flight, and is subject to the friction of the air in its passage through it. A ball fired in vacuo would have thirty-four times the range which it was when fired in air. Another reason that musketry fire does so little execution when delivered by troops aligned, is, that owing to the curvature of the earth, at the distance of 800 yards, a man of ordinary stature, presents a mark of only one-tenth of an inch in altitude or height, and at 1,000 feet, but little more than a twelfth. Colonel Schliminback, of the Prussian service, from a number of calculations extending over a series of battles during the wars which sprung out of the French Revolution, ascertained that a man's weight in lead, and ten times his weight in iron, are consumed before he is put hors de combat! At the battle of Vittoria, nearly four millions and a quarter of ball cartridges and 6,570 round shot and shell were fired by artillery, but the killed and wounded of the French army, consisting of 90,000 men, did not amount to 8,000. The same was true in the Crimean struggle. Notwithstanding the terribly destructive nature of the contest, it is proven that two hundred and eight shots were expended for every man killed! This makes no account of the vast amount of shot and shell used. If even one in ten shot proved fatal, an army would soon be annihilated.
