Designed by Admiral John Dahlgren as a replacement for the sword pattern bayonets then used on the 1861 Plymouth Rifle, the Dahlgren Bowie was made with an eye for the kind of brutal, up-close combat that unfolds during boarding actions, shore landings, and similar events. As such, Admiral Dahlgren's bowie was a combat knife first, and a bayonet second. 16 3/4 inches overall, with a 12 inch asymmetrical clip point blade, marked "USN/D.R/1864" and "(anchor)/P/G G" on the right ricasso and bearing the Ames address on the left. Brass and wood grip, with a "DR" cartouche on the pommel. Leather scabbard, with a brass throat and tip.

Fine, with spotting and dings on he blade, a mixed aged patina on the brass, and mild dents and scuffs on the grip. The Ames address has faded slightly, and some chips are present on the edge. Sheath is also fine, with some flaking of the leather and dents on the brass.
