In December 1760, The
89th regiment embarked at
Portsmouth for the
East Indies, and arrived at
Bombay in November following. The
Duke of Gordon was desirous of accompanying the regiment, but, at the request of his mother,
George II of Great Britain induced him to remain at home to finish his education by telling him that, "there being only nine dukes in the Kingdom of Scotland", he could not be spared. The 89th had no particular station assigned to it, but kept moving from place to place until a strong detachment under Major Hector Munro joined the army under the command of Major
John Carnac, in the neighbourhood of
Patna. Major Munro then assumed the command, and being well supported by his men, quelled a formidable mutiny among the troops. After 20
Sepoys had been executed by Major Munro by blowing them off guns, and with discipline restored, he attacked the enemy at
Buxar, on 23 October 1764 in what became the
Battle of Buxar. Though the force opposed to him was five times as numerous as his own, he overthrew and dispersed it. According to historian
John William Fortescue, the Mughal troops had 2000 men killed, and left 133 pieces of cannon on the field; whilst Munro's troops had 289 killed, 499 wounded and 85 missing. Major Munro received a letter of thanks on the occasion from the President and Council of
Calcutta. "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. == Member of Parliament ==
