Battle on the Ice

The Battle on the Ice was fought between the Republic of Novgorod led by prince Alexander Nevsky and the crusader army led by the Livonian branch of the Teutonic Knights on April 5, 1242, at Lake Peipus. The battle is notable for having been fought largely on the frozen lake, and this gave the battle its name.

The battle was a significant defeat sustained by the crusaders during the Northern Crusades, which were directed against pagans and Eastern Orthodox Christians rather than Muslims in the Holy Land. The Crusaders' defeat in the battle marked the end of their campaigns against the Orthodox Novgorod Republic and other Slavic territories for the next century.

The event was glorified in Sergei Eisenstein's historical drama film Alexander Nevsky, released in 1938, which created a popular image of the battle often mistaken for the real events. Sergei Prokofiev turned his score for the film into a concert cantata of the same title, with "The Battle on the Ice" being its longest movement.

Background
Hoping to exploit Novgorod's weakness in the wake of the Mongol and Swedish invasions, the Teutonic Knights attacked the neighboring Novgorod Republic and occupied Pskov, Izborsk, and Koporye in autumn 1240. When they approached Novgorod itself, the local citizens recalled to the city 20-year-old Prince Alexander Nevsky, whom they had banished to Pereslavl earlier that year. During the campaign of 1241, Alexander managed to retake Pskov and Koporye from the crusaders.

In the spring of 1242, the Teutonic Knights defeated a detachment of Novgorodians about 20 km south of the fortress of Dorpat (Tartu). Led by Prince-Bishop Hermann of Dorpat, the knights and their auxiliary troops of local Ugaunian Estonians then met with Alexander's forces by the narrow strait (Lake Lämmijärv or Teploe) that connects the north and south parts of Lake Peipus (Lake Peipus proper with Lake Pskovskoe).

Battle
On April 5, 1242. Alexander, intending to fight in a place of his own choosing, retreated in an attempt to draw the often over-confident Crusaders onto the frozen lake. The crusader forces likely numbered around 2,600, including 800 Danish and German knights, 100 Teutonic knights, 300 Danes, 400 Germans and 1,000 Estonian infantry. The Russians fielded around 5,000 men: Alexander and his brother Andrei's bodyguards (druzhina), totalling around 1,000, plus 2000 militia of Novgorod, 1400 Finno-Ugrian tribesman and 600 horse archers.
