"The signal victory you gained", they say, "so as at one blow utterly to defeat the designs of the enemy against these provinces, is an event which does so much honour to yourself, Sir, in particular, and to all the officers and men under your command, and which, at the same time, is attended with such particular advantages to the Company, as call upon us to return you our sincere thanks."

For this important service Major Munro was immediately promoted to the brevet rank of lieutenant colonel.

In 1768, Returning home, he was elected as Member of Parliament for the Inverness Burghs, which he continued to represent for over thirty years, though much of this period was spent in India.
