Ketchum Grenade
The Ketchum Hand Grenade was a type of grenade used in the American Civil War. It was patented on August 20, 1861 by William F. Ketchum, a mayor of Buffalo, N.Y., and was partially adopted in the Union Army. They were used in battles such as Vicksburg and Petersburg (both major sieges in the war).
==Overview==
The grenades have the appearance of a cast-iron ball, or a skinny dart, having fins of cardboard to stabilize the flight. They assured landing on the nose, which was backed by a percussion cap that set off the main powder charge in the body. The grenades were largely inefficient because they had to land on their nose to detonate. In one incident Confederates caught them in blankets and hurled them back at the attackers.
Ketchums came primarily in 1, 3 and 5 lb. varieties. The most recognized Confederate copy is the Raines Grenade; it was even less effective. In most cases, the body was the same, but a long cloth streamer was substituted for the fins, and the plunger was a contact explosive.
