 The Copenhageners had been forewarned by spies, so they had planned their defences well and stockpiled weapons and ammunition.The walls of Copenhagen bristled with about 300 pieces of cannon, mortars and other artillery, while a diverse mixture of weapons, ranging from muskets and arquebuses to morningstars, scythes, boiling water and tar had been readied for action.Craftsmen, students and other civilians were divided into nine companies, and each of these companies was allocated a part of the wall to defend.
