An article from the same site mentioning Sumner in Nov 1861:
DAILY CONSTITUTIONALIST [AUGUSTA, GA], November 21, 1861, p. 3, c. 3
Georgia Arms.
—
Wright’s Legion, commanded by Hon. A. R. Wright, the Representative from the 10th Georgia Congressional District, arrived here a few evening’s since, and are encamped in the vicinity. They number about a thousand men, and are all from the upper portion of the State. They are a fine body of men, and their arms, in some respects, different from those
of any other command in the service. Some three companies, or perhaps more, are armed with pikes, a most formidable weapon for close quarters, and of Georgia invention.
Long blades of steel are inserted in a handle of wood some six feet in length, and are suddenly thrown out by pressure on a spring or trigger at the opposite end. These blades or pikes are about two inches in width, and fifteen inches long. The field pieces of the Legion are also worthy of note. They consist of four beautiful rifled six pounders, three rifled twelve pounders, breech loading, with double chambers, and a rifled gun, mounted on wheels, with percussion attachments, and capable of throwing a ball with accuracy some four miles.
These pieces are all of Atlanta manufacture, and, except the first mentioned, the invention of Mr. W. Sumner, of the Georgia Railroad workshops. The design and workmanship
are both admirable, and we expect great execution from them when brought into action under the control of the gallant men of the Legion.
