At that time, under ordinary circumstances, young gentlemen obtained commissions in the army in one of two ways. Free commissions were granted to a limited number of the sons of officers who had performed good service for their country, and all other commissions were purchased, upon the recommendation of two or more officers of high rank. There were no examinations or other means of ascertaining the standard of education of the would-be officer, and it may be taken that Sam Rice was better educated than most young officers who then joined the army. The greater number of commissions were obtained by purchase, but in times of war, when the supply of officers was short, colonels of regiments were allowed to employ the services of young gentlemen (usually ensigns of militia), who were termed "volunteers," and who hoped, by distinguishing themselves on active service, to be granted free commissions. During the many years of war which terminated with Waterloo, a vast number of officers entered the army in this way, and being, for the most part, men whose very livelihood depended upon their zeal, proved themselves valuable officers. The so-called purchase system, in one form or another, was almost as old as the British standing army itself, and dated back to the time when the colonel of a regiment was entirely responsible for his corps, which was known by his name. For many years there was no fixed scale of charges for commissions, the colonels charging more or less what they liked, and employing agents to sell the commissions, so that both the colonels and the agents feathered their nests very satisfactorily. In this manner many useless officers found their way into the army, and it was not until 1765 that the authorities took the matter up and issued strict regulations on the subject. Then the price to be paid to Government for a commission as Ensign, and for promotion to each subsequent rank, was clearly laid down, the colonels being forbidden to make any profit for themselves, though the matter of what was termed "over regulation" was not touched on, but left to the regimental officers themselves.
