[1] The regiment was sent to join the Duke of York's army in the Netherlands in summer 1794 as part of the unsuccessful defence of that country against the Republican French during the Flanders Campaign.

[2] The regiment embarked for the West Indies in autumn 1795 and, after a difficult voyage, two companies took part in the capture of Grenada and the siege of Saint Lucia before returning to England in summer 1796.

[3] The regiment sailed from India for Egypt in December 1800 for service in the Egyptian Campaign reaching Cairo on the day that the French troops surrendered.

[5] The battalion sailed for South America in April 1807[5] and took part in the disastrous expedition under Sir Home Popham: it saw action in the unsuccessful attack on Buenos Aires in July 1807.

[8] Captain William Parker-Carroll remained in Río de la Plata and was well-treated by the Spanish troops.

[12] Then, at the Battle of Bussaco in September 1810, the battalion, under the command of Lieutenant-Colonel John Wallace, together with a detachment of the 45th Regiment of Foot, made a bayonet charge which sent the French troops reeling.

[15] The battalion, still under the command of Lieutenant-Colonel Wallace made another bayonet charge at the Battle of Fuentes de Oñoro in May 1811 and drove the French Army from the village.

Its service in the Crimean War was recognised by the presentation to the City of Galway of a pair of cannons which remain on public display.
