The Battle of Koporye took place on October 8, 1708 close to Koporye, in the Swedish Empire during the Ingrian campaign in the Great Northern War. A Swedish force consisting of 1,800 men[1] under the command of generals Carl Gustaf Armfeldt and Anders Erik Ramsay attacked a numerically stronger enemy of between 2,000 and 3,000 Russian forces. The battle ended in a Swedish victory with about 600 Russians killed and only 70 dead among the Swedish force.[2] After further campaigning, the Swedish–Finland army under the command of Georg Lybecker decided to evacuate his troops, having failed at his objectives.[3]
