Exclusion Crisis
The regiment was listed on the English military establishment as the First Foot or Royal Scots, a temporary measure during the Exclusion Crisis of 1679–1681. Four of its twenty-one companies joined the Tangier Garrison in April 1680, with another twelve in September. It was awarded a battle honour for 'Tangier' in 1908, but the colony and its garrison was evacuated in 1684. A war diary for 1680 was kept by its commander, Sir James Halkett, allegedly one of the first examples to survive.
