Battle of The Vorskla River - Vytautas' Expeditions

Vytautas' Expeditions

Vytautas gathered a large army which included Lithuanians, Ruthenians, Russians, Poles, Moldavians, and Wallachians. To enlist support from the Teutonic Knights, Vytautas signed the Treaty of Salynas, surrendering Samogitia to the Knights. Vytautas's son-in-law, Vasily I of Moscow, formally a Tatar vassal, did not join the coalition. The joint forces organized three expeditions into Tatar territories, in 1397, 1398, and 1399. The first expedition reached the Black Sea and Crimea. Vytautas took several thousand captives without much opposition. Half of these captives were settled near Trakai and awarded privileges to practice their faith. Communities of their descendants, Lipka Tatars and Crimean Karaites (Karaims), survive to this day.

In 1398, the army of Vytautas moved from the Dnieper River and attacked northern Crimea, reaching as far east as the River Don. In order to strengthen his position, Vytautas built a castle at the mouth of Dnieper. Inspired by their successes, Vytautas declared a "Crusade against the Tatars" and in May 1399 received blessing from Pope Boniface IX. The papal blessing for the crusade was an important political achievement for Lithuania, a country converted to Christianity only in 1387 and the subject of a hundred-year crusade. The campaign was organized from Kiev. In 1399, the army of Vytautas once again moved against the Horde along the Dnieper River. On August 5, his army met the Tatars at the Vorskla River just north of Poltava (almost same location as the Battle of Poltava of 1709).
