In August 1576 Bathory led 2,000 (Polish soldiers and mercenaries from Transylvania and Wallachia[REF]) men to Malbork (Marienburg), from there Polish units took control the area surrounding Gdansk, capturing Grabina and Głowa, two strategically important villages, thereby blockading Danzig's port from the east and the south.
With the coming of the spring of 1577, the fighting began anew.
