The siege of Fellin was one of the final events that took place in August 1560 during the Russo-Livonian War. Besiegers used artillery fire exclusively to capture the strong fortress. In July 1560, the Russian army marched on the Fellin fortress, the Livonian knights tried to resist it in the field, but they were defeated in the battle of Erms. On 17 August, the fortress was besieged and after three days of "hellish" shelling, it surrendered. As a result of this siege, the entire Livonian order actually disintegrated and was divided between its closest neighbors - Lithuanians, Poles, Swedes and Russians.
