The Earl of Argyll's Regiment of Foot was a 17th-century Scottish infantry regiment, raised from the men of Argyll, and based at Fort William. The Colonel in Chief was the Earl of Argyll, although this was a nominal appointment, and he did not exercise his command or take part in the regiment's actions. Private soldiers were also called Sentinels in Argyll's regiment of Foot. The regiment was a regular line regiment, rather than a highland militia, and was based at Fort William, under the command of Colonel John Hill, an experienced English officer who had fought with Cromwell during the English Civil War. Captain Robert Campbell of Glenlyon received 8 shillings per day as a senior officer.
