The regiment was deployed briefly to Ireland and southern England, then to Flanders in 1794 where it took part in an unsuccessful campaign under the command of the Duke of York during the French Revolutionary Wars. On its return to England the 79th Foot was listed for disbandment, with the men being drafted into other units. In the end the regiment was reprieved, being instead posted to the West Indies in 1795; after a two-year tour the 79th returned to England again. The regiment was again in action against the French at the Battle of Alkmaar in October 1799 during the Helder Campaign. In 1800 the 79th was part of a force that took part in a failed assault on the Spanish coast at Ferrol.
