TALES OF VALOR HALF-HISTORY: Osowiec Fortress | On August 6, 1915, as usual Poland became a hotbed area of battles between the Russian Empire and Germany. When the Germans decided to unleash poisonous gas on the enemy to try and take the fortress they'd been attempting to get for 11 months, the Russians didn't go down without a fight that saved the fortress for another future fight. The Russian "attack of the dead" is the stuff of zombie scenes, as you'll soon hear!
