The forces of Rajadhiraja Chola had been successful to sack Kollipakkai, Kampilli, Pundur, Yetagiri and the Chalukyan Capital Kalyani. But before 1050 AD, Someshwara was able to make a dramatic recovery. He was successful in driving out the Chola forces of his capital and he carried war in the heart of the Chola kingdom. In 1053-54 AD, Rajadhiraja and his younger brother ____________ed a campaign against the Chalukyas.
