In the talks with Austrian representatives in the village of Tešići near Niš on 24 July 1737, Petrović and Patriarch Šakabenta promised Field Marshal Seckendorff that they would mobilise the Kuči and other Highland tribes.
[5] Petrović asked Field Marshal Seckendorff that, in the event that the rebels won, he would oversee the troops in his stead.

Epic poems have been written about his life, including Ustanak sedmoro Brda i Arbanasa (The Uprising of the Seven Hills and the Albanians).
