The siege of Belaya was the final military episode of the Smolensk War. The defense of the fortress by its small Russian garrison against a large Polish-Lithuanian army of King Władysław IV Vasa thwarted the king's plan to march against Moscow and made him sign the Treaty of Polyanovka in which he relinquished his claims to the Russian throne.
