[1] The Chola army went on to raid East Bengal and defeated Govindachandra of the Chandra dynasty and invaded Bastar region.

(He seized) Śakkarakkōţţam, whose warriors were brave; Madura-maṇḍalam destroyed in a trice, the prosperous city of Nāmaṇaik-kōṇam with its dense groves.

Pañcap-paḷḷi whose warriors (bore) cruel bows, Māśunideśa with its green fields; a large heap of family-treasures with many (other) treasures (which he carried away), after having conquered Indraratha of the ancient race of the moon, together with (his) family, in a fight which took place at Ādinagar, (a city) whose fame knew no decline; Oḍḍa-viṣaya which was difficult of approach on account of its dense forest defence; the good Kōśalai-nāḍu where Brahmins assembled; Taṇḍabutti in whose gardens bees abounded, (land which he acquired) after having destroyed Dharmapāla (in) a hot battle; Takkaṇalāḍam, whose fame reached (all) directions, (and which he occupied) after having forcibly attacked Raṇaśura; Vangāḷa-deśā, where the rain water never stopped, (and from which) Gōvindacandra fled, having descended (from his) male elephant; elephants of rare strength, women and treasure, (which he seized) after having been pleased to put to flight in a hot battlefield the strong Mahipāla by the sound of a conch from the deep sea; Uttiralāḍam (on the shore of) the expansive ocean (producing) pearls; and the Gangā whose waters bearing flagrant flowers dashed against the bathing places (tirtha)Sakkarakottam, the place from where Araiyan Rajarajan led the campaign into Bengal is identified with the town of Chakrakotya or Chitrakoot, in present-day Madhya Pradesh.

He was met by Rajendra I on the banks of the Godavari and the combined armies returned home after conducting Rajaraja Narendra's coronation as the king of the Eastern Chalukyas.

That the campaign was military in nature is suggested by the last line of the Thiruvalangadu plates which state that the king erected a Ganga-jalamayam jayasthambham or a "liquid pillar of victory" in the form of the Cholaganga tank.

According to R. D. Banerji, a Kannadiga chief who accompanied Araiyan Rajarajan on his campaign settled down in Bengal and founded the Sena dynasty.
