The regiment embarked for Holland in August 1799 and saw action at the Battle of Alkmaar in October 1799 during the Anglo-Russian invasion of Holland, an intervention which was aimed to overthrow the Batavian Republic, a French client republic. It returned home later that month. The regiment embarked for Menorca in June 1800 and then sailed on to Abu Qir in Egypt in March 1801 to take part in the Egyptian Campaign. It saw action at the Battle of Mandora in 13 March 1801. This was a preliminary action before the Battle of Alexandria eight days later on 21 March. That morning, the regiment had been ordered to return to Abukir, having now only 150 effective men, because of illness and casualties sustained. However, on hearing the sound of firing, the regiment saw the commander-in-chief, Sir Ralph Abercromby, passing on his horse and called out to be allowed to return to the line of battle, to which he gave his assent. The regiment sailed for home in October 1801.
