Illuminated Chronicle of Ivan the Terrible, Laptev volume: Life of Alexander Nevsky
In 1240, after taking possession of Koporye and Pskov, the Teutonic knights invaded the Republic of Novgorod. Alexander reclaimed Koporye then liberated Pskov. He attacked the knights' territories, but troops from Riga crushed the Russian vanguard, which retreated to Lake Peipus. Both sides then prepared for a decisive battle on the frozen lake. Believing victory to be at hand, the heavily armed Teutonic knights pursued Alexander over the ice, which cracked under their weight. They suffered a crushing defeat, and had to relinquish their conquests.
