In 1787 he offered to raise a regiment on his own estates to be commanded by himself. The government declined his patriotic offer but accepted his services in procuring recruits for the 74th and 75th. On 19 May 1790 he renewed his offer but the government again declined his services. When war broke out in 1793 he offered for a third time and a letter of service was granted in his favour dated 7 March 1793 empowering him as Lieutenant-Colonel-Commandant to raise a Highland Battalion to be called 78th (Highlanders) Regiment of Foot.
