A fortified defense line guarding the crossing of the Narew River was located near the village of Wizna. Captain Władysław Raginis had an infantry battalion, including a fortress company and an engineer company, at his disposal. The battalion occupied eight reinforced concrete bunkers, with the one located on Góra Strękowa serving as the headquarters.
Captain Władysław Raginis, swore to hold his position as long as he was alive. When the last two bunkers under his command ran out of ammunition, he ordered his men to surrender their arms and he himself then committed suicide by throwing himself on a grenade.
The lessons learned by the German Army in its operations in Poland were put to use in the later campaigns against the western Allies, the Balkan states, and the Soviet Union. Poland also formed the testing ground for new theories on the use of armored forces and close air support of ground troops.
