Which naval small arm saw the most action?
Short answerThe Brown Bess is a plausible firearm candidate, but cutlasses and especially long-lived boarding pikes broaden the answer beyond guns.
NotesThe Brown Bess is a plausible firearm answer, while the Lee-Enfield also had a long service life. The category then widens beyond guns to cutlasses and boarding pikes, which remained common across a much longer period. A boarding pike is a shortened polearm suited to the confined spaces of a ship. The answer distinguishes the service life of a weapon family from the number of particular naval actions in which one model appeared.
