Russia subsequently suffered a series of disastrous defeats in the field. In 1512, Grand Hetman of Lithuania, Konstanty Ostrogski, ransacked the region of Severia and vanquished a Russian force of approximately 6,000 men. On 8 September 1514, Muscovy suffered a major defeat at the Battle of Orsha, which prevented the Russians to place all the former Kievan Rus' lands under their lordship. Poland exploited the battle for propaganda purposes with strong anti-Russian sentiment. A letter sent to Rome stated that "Muscovites are not Christians; they are cruel and barbaric; they are Asians and not Europeans; they are in league with Turks and the Tatars to destroy Christendom".
