In 1633 Koniecpolski thwarted the Turks' attacks on the Commonwealth, defeating their forces on 4 July at Sasowy Róg.
In 1635, in the short lived Sulima Uprising, after Cossacks under Ivan Sulyma captured and destroyed the Polish Kodak Fortress (near modern Dnipropetrovsk), Koniecpolski led an expedition that retook the fort and punished the insurgents.
