Archaeological findings in the wreck of the Danish royal warship “Gribshunden” have revealed a chest containing tools for producing lead ammunition for early handguns. This discovery suggests that naval warfare was undergoing significant changes in the 15th century, transitioning from close-quarters combat to long-range gunfire. The chest, identified as a “zeuglade” for ammunition production, also hints at the presence of German mercenaries on board the ship at the time of its sinking.
