For a while the Cholas did not press their cause either in Vengi or Kalinga. However, in c.1054, the Cholas responded by invading Koppal (Koppam) where King Rajadhiraja Chola was killed and Someshvara I had to mourn the death of his brother Jayasimha. However, according to Sastri, the Cholas were able to convert defeat into victory when their crown prince Rajendra II (brother of Rajadhiraja) mounted a surprise counterattack and pushed the Chalukya armies back. Rajendra II crowned himself on the battlefield, mounted a victory pillar at Kollapura (modern Kohlapur) and returned to his capital Gangaikondacholapuram with much booty which including the Chalukya queens Sattiyavvai and Sangappai. Hostilities continued and in c.1059 Rajendra Chola II invaded the Chalukya kingdom but was defeated on the banks of the Tungabhadra river. Someshvara I constructed a temple at Annigeri in the modern Dharwad district to celebrate this success. However, according to Sen, in the battle of Mudakkarru on the banks of the Tungabhadra in c.1059, Someshvara I suffered another defeat.
