Venta River
Numerous rebellions against the Teutonic Order across all Baltic lands followed, including the Great Prussian Uprising, which lasted from 1260 to 1274. Zemgale rebelled for 30 years while Courland surrendered in 1267. The Curonians, together with the Samogitians, attacked Teutonic castles west of the Venta River. On 3 February 1261, on their way back, the pagans again defeated the knights near Lielvārde (Lennenwarden), killing 10. Oeselian rebellion was suppressed in 1261. These battles undid some 20 years of Livonian conquest and it took some thirty years for the Livonian Order to restore its control.
