According to the historian Kamath, soon after his coronation, Someshvara I interfered in the affairs of Vengi and invaded the region but faced defeat against the Chola monarch Rajadhiraja Chola (crowned in c.1044) at Amaravathi. The Cholas followed this by invading Chalukya territory. According to the historian Sastri, Rajadhiraja defeated Someshvara I in the battle of Dannada ("Dhanyakataka") on the banks of the Krishna river compelling the Western Chalukya armies to retreat, and the fort at Kollipakki (Kulpak) was razed to the ground. This was followed by victories at Kampili and Pundur. According to the historians Chopra et al., the details of the sack of Kampili is recorded in the Manimangalam inscription. A victory pillar with the Chola emblem was installed at Yetagiri (modern Yadgir in the Yadgir district). Finally, the Cholas plundered Kalyani, the Chalukya capital in c.1045. Rajadhiraja performed the "Virabhisheka" ("victory celebration") in the destroyed enemy capital and assumed the title "Vijayarajendra" ("victorious Rajendra"). However, according to Sastri and Sen, in a dramatic recovery, Someshvara I drove the Cholas out of Vengi by c.1050 and re-established his influence, not only in Vengi but also in Kalinga (modern day Orissa). Sen further claims Someshvara I took the battle right to the heart of the Chola empire. According to Kamath there was a Chalukya counterattack and a raid on Kanchipuram.
