These three swords are presumed to have belonged to Captain Isaac Plumb. Acquiring a special sword is mentioned in Captain Plumb's correspondence with his uncle Henry Grant on December 20 and 29, 1862 and February 10, 1863; however, it is difficult to know if any of the swords in the collection are the ones referred to in the letters.

The first sword, circa 1848 to 1861, was made by Thomas Warren. It is 37.5 inches with a metal pommel, a metal crossguard with the guard wrapped in leather, and a grip wrapped in decorative wire. It's double-edge straight blade has decorative engraving and is stamped "Warren, 23 Cursitor St. London." The second sword is 40 inches with a metal pommel, a wooden grip, and a curved blade stamped "H & C" near the crossguard. The last sword is 31.5 inches with a metal pommel in the shape of a plumed helmet, a double-edged straight blade with decorative engraving, and a crossguard with a patriotic shield emblem.
