The towns of the upper Mahanadi and Tel basins in the old Kosala: Sonepur (Suvarnapura), Binka (Yayatinagara), Patnagarh and Sambalpur.
English Wikipedia says the Ganga kings fought the Kalachuris of Ratnapura for the Sambalpur-Bolangir tract, failing under Kamarnava VII and winning it under Anangabhima III (after the battle at Seori Narayana near the Bhima). The campaign board marks Binka and Patnagarh "contested". In 1200 the tract is held by custom, not garrison.
