Ferguson was inured by years of service to such hardships. His loyalty was rewarded on October 25, 1779, when he was promoted to the rank of major. A few months later, at the start of the British expedition against Charleston, he was given the temporary rank of lieutenant colonel. His ability and personal magnetism enabled him to win the respect of all his associates, and his success as an officer was as notable in the South as it had previously been in the North. This was his last campaign, and, in its course, he demonstrated a sense of fairness and a degree of humanity that earned him the respect of many of the people of the South. As the opportunity permitted, he attempted to persuade many of these Americans to renew their oath of allegiance to the King of England. His success won the admiration of his associates, among whom was General Stuart of Garth, who wrote upon the demise of this soldier: “By zeal, animation, and a liberal spirit, he gained the confidence of the mass of people....” Even more revealing of his character are the following lines written from America by Ferguson to his mother to calm her fears for his safety: “The length of our lives is not at our command, however much the manner of them may be. If our Creator enable us to act the part of honour, and to conduct ourselves with spirit, probity, and humanity, the change to another world whether now or fifty years hence, will not be for the worse.” _The Ferguson Rifle_ Great as Maj. Patrick Ferguson’s success was as a soldier, probably his most outstanding achievement was the development of the first breech-loading rifle to be used by troops in battle. This arm, which is known as the Ferguson rifle, was expected by its inventor to bring revolutionary changes to gunnery practices. In the patent, which was granted by the British Patent Office on December 2, 1776, Ferguson describes it as “... an arm which unites expedition, safety, and facility in using with the greatest certainty in execution, the two great dessiderata [sic] of gunnery never before united.” This rifle corrected many inadequacies of earlier breechloaders. Its center of interest was the screw-plug attached to the trigger guard which passed directly through the breech of the barrel from the bottom to the top. This plug had from 12 to 14 rapid twist threads so that with one turn of the trigger guard the loading aperture in the top of the barrel could be opened or closed. The single-screw thread on breech plugs of earlier breechloaders made it necessary to rotate the trigger guard three or four times to open or close the breech. The Ferguson screw-plug had the further advantage of being so designed that it never came completely out of its socket.
