Raised as personal bodyguards to the Maharaja of Travancore, the unit, though redesigned through the ages, continues to retain its individual identity with no history of disbandment or re-raising.

[2] The Travancore Army, known as the Nair Brigade, completely exterminated the superior and better equipped Dutch Forces which landed at Colachal in July 1741 during the reign of Anizham Thirunal Veer Bala Marthand Varma.

In the Battle of Colachel, during the Travancore–Dutch War, Capt Eustachius De Lannoy, a Commander of the Dutch fleet, was captured and was asked later to train the Travancore Army.

From 1741 to 1758, Capt De Lannoy remained in command of the Travancore Forces and was involved in annexation of small principalities.

The then-incumbent President of India, V. V. Giri, presented Colours to the battalion on 23 May 1970 at Barrack Square, Wellington at a solemn ceremony.
