After a long pause in open hostilities, Swedes purportedly undertook an attack against Novgorod in 1240. The only source of information on the attack is a Novgorodian chronicle. Soon after their fleet entered the mouth of the Neva River, the Swedes were roundly defeated in the Battle of the Neva by a young prince, Alexander of Novgorod, who would later be given the epithet "Nevsky" to memorialize this victory.
