"The Bonny Bunch of Roses" (Roud 664, Laws J5) is a folk song written in the 1830s by an unknown balladeer from the British Isles, perhaps with Irish sympathies.
Napoleon was defeated because he failed to beware of the 'bonny bunch of roses' - England, Scotland and Ireland whose unity cannot be broken.
With this in mind, it should perhaps come as no great surprise then if Napoleon's bravery captivated the imagination of a segment of the Irish population, nor his defiance even in defeat.
On the other hand, the song stresses the unity of the English, Scots and Irish, suggesting acknowledgement of a common British identity in opposition to France and Napoleon among the soldiers from those three nations at the time.
