Harry Munro's company was one of three in the process of being raised in the North when the Commander in Chief in Scotland, General Sir
John Cope arrived at
Inverness on 29 August. Harry's uncle George Munro, 1st of Culcairn met Sir John Cope and agreed that the Munros "should instantly take arms and join the King's troops" and the next day Harry brought in 200 of his men in three companies. These three companies were raised by Harry Munro himself, Hugh Munro of
Teaninich and William Munro of
Achany. Three other companies of Loudoun's regiment raised in Argyll from the
Clan Campbell came under the Duke of Cumberland's command in his march north from
Stirling but they were used mainly as scouts and baggage guards. However, several of them, including one officer were killed when they fought at the
Battle of Culloden. Loudon's Highlanders Regiment was at Culloden but Harry Munro himself was listed as absent "by HRH leave" presumably to try to deal with the problems at
Foulis Castle which had been burned after the Battle of Falkirk. At the request of
Simon Fraser, 11th Lord Lovat, Harry Munro of Foulis and Ludovick Grant of Grant visited Lovat while he was imprisoned in the
Tower of London having received the death sentence. After the suppression of the rebellion, Loudon's Highlanders later took part in the
mopping up operations based at
Fort Augustus. The regiment remained in Scotland until May 1747 when they embarked at Bruntisland to join the allied army under Cumberland in
Flanders. The Munro company under Harry appears to have stayed in Scotland but in a letter from another officer in March 1748, Sir Harry is said to be going over to join the regiment. However, with the ending of the war in Flanders, Loudon's regiment was ordered back to Scotland and reduced at Perth in June of that year. ==Member of Parliament==
