CAPTAIN (French capitaine, Italian capitano, from the Latin caput), literally a head, or chief officer; but the term is used in particular to denote an officer holding a certain rank in the army or the navy. In the army, a captain is the officer who commands a troop of cavalry, or a company of infantry, or of artillery. His full pay in horse regiments is 14s. 7d. a-day; in the infantry 11s. 7d. Captains in the Life and Foot Guards rank with the Colonels of other regiments, and their full pay is 15s. a-day.
