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.

[3] Harry joined Sir John Cope at the Water of Nairn and when the army marched for Aberdeen on 4 September Loudon's Highlanders regiment included his three companies, while George Munro of Culcairn's detachment acted as scouts.

[3] Sir John Cope remained in Aberdeen where a fourth company of Loudoun's regiment joined the others until 14 September from where they sailed to Dunbar and had their infamous defeat at the Battle of Prestonpans.

[3] Harry was among 70 officers taken prisoner and for a time was imprisoned in Glamis Castle but by mid January 1746 he was among 31 men released who arrived at Edinburgh, where he learnt the news of the deaths of his father Robert and his uncle Duncan after the Battle of Falkirk (1746).

[3] The commander of British forces, Prince William, Duke of Cumberland, had no wish to have the support of any Highland troops at the time for he distrusted them all and deliberately gave the Earl of Loudoun no help to extricate himself from his difficulties with the Jacobites in the north.

[4] 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.

[3] 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.
