Description:
The famous Volunteer force collapsed somewhat abruptly and ignominiously in 1793; and a militia force was the only safeguard of peace in the country which was seething with sedition and evidently heading for rebellion. In 1796 a yeomanry force, cavalry and infantry, officered by local gentlemen was raised for preserving order.
