The song does contain one major innacuracy when it says "the leader was a Limerick man, Sean South of Garryowen". According to IRA histories the group was led by Sean Garland of Dublin, second in command was David O'Connell of Cork.                              

Garland was badly wounded and wanted to stay in the barn with South and O'Hanlon and shoot it out with the RUC to allow his men more time to get over the Border. However he was talked out of this and helped away. Earlier IRA histories say that about half the men were wounded but in the new book on Joe Cahill it says "another member of the Brokeborough raiding party revealed that all the volunteers on the operation had been wounded".
