The coal torpedo was a hollow iron casting filled with explosives and covered in coal dust, deployed by the Confederate Secret Service during the American Civil War, and intended for doing harm to Union steam transportation. When it was shoveled into the firebox amongst the coal, the resulting explosion would at the very least damage the boiler and render the engines inoperable. At worst, a catastrophic boiler explosion would kill crewmen and passengers, start a fire, or even sink the vessel.
The Colt Revolving Belt Pistol or Navy Pistol, sometimes erroneously referred to as "Colt Revolving Belt Pistol of Naval Caliber" or "of Navy Caliber", is a cap and ball revolver that was designed by Samuel Colt between 1847 and 1850.

The family of Colt Pocket Percussion Revolvers evolved from the earlier commercial revolvers marketed by the Patent Arms Manufacturing Company of Paterson, N.J. The smaller versions of Colt's first revolvers are also called "Baby Patersons" by collectors and were produced first in .28 to .31 caliber, and later in .36 caliber, by means of rebating the frame and adding a "step" to the cylinder to increase diameter. The .31 caliber carried over into Samuel Colt's second venture in the arms trade in the form of the "Baby Dragoon"-a small revolver developed in 1847–48. The "Baby Dragoon" was in parallel development with Colt's other revolvers and, by 1850, it had evolved into the "Colt's Revolving Pocket Pistol" that collectors now name "The Pocket Model of 1849". It is a smaller brother of the more famous "Colt's Revolving Belt Pistol of Naval Caliber" introduced the same year and commonly designated by collectors as the "1851 Navy Model". In 1855 Colt introduced another pocket percussion revolver, the Colt 1855 "Sidehammer", designed alongside engineer Elisha K. Root.

A derringer is a small handgun that is neither a revolver nor a semi/fully automatic pistol. It is not to be confused with mini-revolvers or pocket pistols, although some later derringers were manufactured with the pepperbox configuration. The modern derringer is often multi-barreled, and is generally the smallest usable handgun of any given caliber and barrel length due to the lack of a moving action, which takes up more space behind the barrel. It is frequently used by women because it is easily concealable in a purse or a stocking.

The M1854 model was a single-action, pinfire revolver holding six rounds. It was a French military revolver chambered for the 12 mm pinfire cartridge, based on a design by Casimir Lefaucheux. The M1854 revolver spawned numerous variants, some of which were produced under license in other countries. It was widely exported during the 1860s and sold as both a military and civilian sidearm with either a short or long barrel. Most military models were produced only with single-action whereas civilian models were made primarily with double action.

The Lefaucheux M1858 was a French military revolver developed for the navy, chambered for the 12 mm pinfire cartridge, and based on a design by Casimir Lefaucheux and his son, Eugene.

The 1858 was later upgraded in the late 1860s as the Lefaucheux de Marine 1870. It was accepted by the French Navy, but only 150 copies were delivered by 1872. Models of the 1858 were also purchased by Spain, Sweden, Italy, Russia, and Norway.

The Model 1840 noncommissioned officers' sword was adopted by the United States military in 1840. Based primarily on a sword used by the French Army, the model 1840 NCO proved somewhat heavy hilted and ill balanced. For over 70 years, it was widely used by the Army; today its usage is restricted to ceremonial occasions. The sword had a 31-inch blade, a cast brass hilt resembling the more expensive wire-wrapped leather grips, and a leather scabbard rather than the steel used by cavalry troopers and officers, although some makers, such as Emerson and Silver, issued a steel scabbard rather than leather to protect from wear. Leather scabbards were phased out beginning in 1868.

A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.

The North-South Skirmish Association (N-SSA) is a historical and competitive organization whose goal is to maintain the knowledge of the unique firearms used during the American Civil War.

They are commonly, though inaccurately, referred to as the Model 1858 due to the patent markings on its New Model barrels, "PATENTED SEPT. 14, 1858/E. REMINGTON & SONS, ILION, NEW YORK, U.S.A./NEW MODEL."; although wide scale production did not start until 1861.
