Long War: Austria captures Transylvania in the Battle of Goroszló.
The Battle of Guruslu or Battle of Goroszl (Hungarian: goroszli csata) was fought on 3 August 1601, between the troops of the Habsburg monarchy led by Giorgio Basta, the Cossacks and Wallachia led by Michael the Brave on one side, and the Transylvanian troops led by Sigismund Bthory on the other side. It was part of a series of military encounters between the Ottoman Empire and opposing European states during 15911606 (see also The Long War).
The Long Turkish War or Thirteen Years' War was an indecisive land war between the Habsburg Monarchy and the Ottoman Empire, primarily over the Principalities of Wallachia, Transylvania, and Moldavia. It was waged from 1593 to 1606 but in Europe it is sometimes called the Fifteen Years War, reckoning from the 1591–92 Turkish campaign that captured Bihać.
In the series of Ottoman wars in Europe it was the major test of force between the Ottoman–Venetian War (1570–73) and the Cretan War (1645–69). The next of the major Ottoman–Habsburg wars was the Austro-Turkish War of 1663–1664. Overall, the conflict consisted in a large number of costly battles and sieges, but with little gain for either side.
