Ketchum If You Can
It may not be the classic “pineapple” that you are used to seeing when you hear the term “hand grenade“. Think of these as the first revision.
This design was patented in 1861 by William Ketchum, the mayor of Buffalo, New York. The grenades were used, sometimes, by the Union army during the Civil War. Unlike the ones that you see today these didn’t have the classic, pull the pin and throw.
Instead, they contained a percussion cap in the nose. All you had to do was throw them and hope they landed nose-first. The fins were there to spin it and to make sure that happened. Of course, that did not always happen. As such, they did not always go off, which made them sort of useless. Needless to say, they were not popular.
During the war, they had documented use in the siege of Petersburg and Vicksburg and a number of specimens have survived. One of the most fascinating stories concerning these comes from the 1863 siege of Port Hudson, Louisiana where the Confederates rigged up a system using blankets to catch the devices, preventing them from going off. Then, of course, they would send them back leading to a high stakes game of hot potato.
With their dubious success, these weapons were relegated to the scrap heap of history and remain a footnote in the Civil War. In case you’re curious. The “pineapple” grenade that is seen in all the WWII movies came into service in Late 1917-18 and underwent a number of revisions before finally ending its service in the 1970s.
