Established in 1741, by 1745 the regiment was in Gibraltar and under the command of a Colonel Warburton, while two years later it was serving in Nova Scotia during Father Le Loutre’s War, the 45th being called out on active service. The regiment participated in the Siege of Louisbourg (1758) and the Battle of the Plains of Abraham. The 45th Regiment served for twenty years in Canada. The regiment also participated in the American Revolution, the Peninsular War, Burmese War, and the Kaffir War.

This was granted the same year, becoming the 45th (1st Nottinghamshire) Regiment.
The regiment returned to the Americas in 1786, spending the next 16 years, with one break, in the West Indies. During this time they saw action against the French as part of the French Revolutionary Wars, at Martinique, Dominica and Les Saintes.
After an expedition to South America in 1807, fighting at Buenos Aires, the 45th returned to Britain, to take part in Wellington’s Peninsular campaign. In this they fought in every major action, winning the nickname “Old Stubborns” at Talavera, and being commended at Busaco and Badajoz.
