Heavy Matchlock Musket (Wall Gun / Rest Gun)

Timeline

1. c. 1500–1535Gunsmithing centers of southern Germany · Southern GermanyIn the early 16th century German gunsmiths experimented with oversized matchlock long guns requiring a fork or wall rest, first used for firing from battlements and blocking key positions; their bore and charge far exceeded ordinary hook guns, forming the technical precursor to the heavy matchlock.
2. c. 1540–1550Free imperial cities and fortresses of the German Empire · Holy Roman EmpireIn the 1540s arsenals of city-states such as Nuremberg and Augsburg stockpiled large quantities of Volkewehr/Hakenbüchse heavy matchlocks, emplaced at wall embrasures and bastion gun positions, combining with light artillery to form layered positional firepower, and were used in combat in conflicts such as the Schmalkaldic War.
3. c. 1570–1620Europe · EuropeIn the late 16th century heavy matchlocks were also used for field breastworks and wagon forts, and some states organized them into independent support detachments; as light cannon and heavier smoothbore guns became widespread, rest guns gradually left front-line service but continued in fortress garrisons into the early 17th century.
