In 1492, the border of Lithuania's loosely controlled eastern Ruthenian territory ran less than one hundred miles from Moscow. But as a result of the warfare, a third of the grand duchy's land area was ceded to the Russian state in 1503. Then the loss of Smolensk in July 1514 was particularly disastrous, even though it was followed by the successful Battle of Orsha in September, as the Polish interests were reluctantly recognizing the necessity of their own involvement in Lithuania's defense. The peace of 1537 left Gomel as the grand duchy's eastern edge.
