The Battle on the Ice, alternatively known as the Battle of Lake Peipus, took place on April 5, 1242. It was fought largely on the frozen Lake Peipus between the forces of the Republic of Novgorod, led by Prince Alexander Nevsky, and the forces of the Livonian Order and Bishopric of Dorpat, led by Bishop Hermann of Dorpat. The battle represented a significant defeat for the Catholic forces during the Northern Crusades and brought an end to their campaigns against the Orthodox Novgorod Republic and other Slavic territories for the next century.
The Teutonic knights and crusaders charged across the lake and reached the enemy, but were held up by the infantry of the Novgorod militia. This caused the momentum of the crusader attack to slow. The battle was fierce, with the allied Russians fighting the Teutonic and crusader troops on the frozen surface of the lake. After a little more than two hours of close quarters fighting, Alexander ordered the left and right wings of his army (including cavalry) to enter the battle. The Teutonic and crusader troops by that time were exhausted from the constant struggle on the slippery surface of the frozen lake. The Crusaders started to retreat in disarray deeper onto the ice, and the appearance of the fresh Novgorod cavalry made them retreat in panic.
It is commonly said that “the Teutonic knights and crusaders attempted to rally and regroup at the far side of the lake, however, the thin ice began to give way and cracked under the weight of their heavy armour, and many knights and crusaders drowned”.
