Because the battle consisted of a small force holding a piece of fortified territory against a vastly larger invasion for three days at great cost before being annihilated, Wizna is sometimes referred to as the "Polish Thermopylae". One of the symbols of the battle is Captain Władysław Raginis, the commanding officer of the Polish force, who 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 committed suicide by putting a grenade between his chin and neck.
