Osowiec was a Russian pivotal fortress built 50 km from Białystok city. During 1914-1915 it was attacked by the German forces three times including a chemical attack. Russian army repulsed all the attempted assaults and withstood the 190-days siege. Defense of the Osowiec fortress is a perfect example of courage and valor of Russian soldiers.
In 1916, Russian forces commanded by General Alexey Brusilov inflicted a serious defeat on Austro-Hungarian and German armies and freed a major part of the Western Ukraine in the course of operation named the Brusilov Offensive.
