1. Velanjeri Copper Plates: In this copper plate it is mentioned that TheAparajitha copper plate says that Aparajitavarman went to Setutirtha. The other set of parantaka copper plate in the same bunch also mentions Parantaka going to setu Theertha. Translation of Section 14 of Velanjeri copper plate of Paraantaka Chola I issued in the 25th year (that is, about 930 Common Era) is as follows: “This ruler (Paraantaka) performed tulaabhaara with gold acquired by his valour, at the beautiful Sriraamatirtha, where the ablest of monkey flocks built the bridge; at the Kanyaatirtha which subdued the southern quarters, and at Srirangam beautiful by the areca groves, where Sri Vishnu reclines on his serpent couch.” Sanskrit text in grantha script of this section reads as follows: “ramie sriramatirthe kavivara nikaraih baddhasetu prabandhe kanyaatirthe jitaanaamadaritamapi dis’e mandane dakshinasyaah srirange caahis’alyaas’ayitamurabhidi s’yaamapoogaabhiraame hemnaaviryaancitena kshitipatikarot yastulaabhaarakarma” http://www.tamilartsacademy.com/articles/article28.xml
2. Thiruvalankadu Copper Plates gives the lineage of Chola, related to Lord Rama. They also mention about their navy they claim to have used ships rather than building a bridge like Rama. ( could not get the text portion of the navy, and request members to give, if they have.)
