"The Gallant Forty Twa" is a traditional Scottish song associated with the 42nd Foot regiment known as the Black Watch.^[1] It is generally dated to the mid-19th century, although it may have been based on an older tune from Ulster. It was reportedly sung by soldiers from the regiment during the Dunkirk evacuation.^[2]

The song was revived by the Irish folk group The Clancy Brothers in the 1960s. It has also been recorded by Ryan's Fancy and Andy Stewart.
