The Pallava king defeated the Chalukya army in the far south and recovered his kingdom, which Vikramaditya I had overrun as far as the Kaveri.
01The Chalukya return
Vikramaditya I spent his first years winning back his father Pulakeshin II’s kingdom, and then carried the war into Pallava country. He took Kanchi, and his Gadval copper plates of 674 were issued from his camp at Uragapura, the old Chola town of Uraiyur on the Kaveri. A Chalukya army was sitting in the heart of the Tamil country. Parameshvaravarman I, who seems to have withdrawn rather than stand siege, gathered his forces and met the Chalukyas at Peruvalanallur, a village near Tiruchirappalli.
02The Kuram plates
The battle is told in the Kuram copper plates, a grant Parameshvaravarman made to a temple at Kuram near Kanchi. They praise his part in the fight at Peruvalanallur in high verse and say the Chalukya king was put to flight with his vast army. Pallava records are not neutral, and the Pandya king Arikesari Maravarman also claimed a victory over the Chalukyas at Nelveli in these same years. What is certain is that Vikramaditya went home and the Pallavas held Kanchi again. The two houses fought on for another eighty years.
Peruvalanallur saved the Pallava kingdom in the generation that built the Shore Temple and the Kailasanatha at Kanchi.
