The Second Battle of Copenhagen (or the Bombardment of Copenhagen) (16 August – 5 September 1807) was from a British point of view a preemptive attack on Copenhagen, targeting the civilian population to yet again seize the Dano-Norwegian fleet. But from a Danish point of view, the battle was a terror bombardment on their capital. Particularly notable was the use of incendiary Congreve rockets (containing phosphorus, which cannot be extinguished with water) that randomly hit the city. Few houses with straw roofs remained after the bombardment. The largest church, ''Vor frue kirke'', was destroyed by the sea artillery. Several historians consider this battle the first terror attack against a major European city in modern times.
