Alexandr Nevsky Lithuanian campaign

The Lithuanian campaign of Alexander Nevsky was the successful actions of the Pereslavl and Novgorod troops led by Alexander Nevsky against the Grand Duchy of Lithuania in 1245.

Prerequisites
Since 1219, Lithuania regularly raided Russian lands. As J. Fennel noted, the collapse of the Principality of Polotsk made it possible for the Lithuanians to launch raids on nearby lands, including Novgorod and Pskov.

The campaign
Russian princes decided to go on a campaign after the Lithuanians attacked the border area and robbed many peaceful Russians. Alexander Nevsky headed to Lithuania, where he freed all the prisoners and defeated the Lithuanians at Lake Zizicekoe. On the way back, the Lithuanians tried to take revenge, but were destroyed again.
