Vaniyambadi in Tamil Nadu derives its name and identity from mythological lore. Vaniyambadi is derived from Vaniampadi = Vani Ammai + Padi (Tamil: வாணி அம்மை + பாடி) which denotes "Vani Ammai" the name of the Goddess Saraswathi, and "Padi" refers the infinitive, "to sing". Legend has it that Saraswati sang on the banks of the Palar River for God Vishnu and God Shiva here, and hence it was named Vaniyambadi. Indeed, temples dedicated to Sundara Varadaraja Perumal (Vishnu) and Athitheeswarar (Shiva) dot both banks of the fast-flowing Palar River. Vaniyambadi, today, is surrounded by lovely hills with many a scenic hill station positioned on them, green farmlands crisscrossed by numerous water channels and a sleepy little town amidst it all.

Vaniyambadi is a well-known place in the history of fights against the British. Hyder Ali and his son Tipu Sultan have been known to have camped in Vaniyambadi during their battles against the British empire, also Vaniyambadi battle is first for Tippu at the age of 17 when his Father was ill.

The Mysorean army set off on its fresh round of campaigning in the beginning of November 1767. According to De la Tour, it was two days after Haidar's mother had departed with her retinue. The main army marched towards Vaniyambadi while another detachment had been sent earlier in the direction of Tirupattur which had again fallen into British hands. The scouting parties of cavalry and infantry had reported an easy approach to Vaniyambadi along the course of the Palar river which flowed past the town and the route was covered with thick undergrowth and trees. Also there was no need of digging trenches for the artillery due to there being a ridge which could serve as a position for the cannons. The garrison there consisted of 30 Europeans with 1000 sepoys, mostly irregulars. The Mysorean army reached the outskirts of the fort at dusk on November 6 and set up a battery of 12 cannons on the ridge at night. The European commander of the artillery received a light wound in the process. Haidar ordered him to rest in his tent and took over the personal command of the battery. Throughout the night he sat under a tree nearby and directed the setting up of the artillery unmindful of the firing by the British who had now noticed his approach. Though this is not mentioned in other sources it is certainly characteristic of Haidar's courage and he would repeat it during the siege of Ambur. He left when the commander returned. The cannons commenced firing soon after dawn on November 7 and soon the British garrison in Vaniyambadi capitulated, probably due to its inadequate strength though no breach had been made.
