Bonny Light Horseman

I first heard this song sung by Eliza Carthy but this version came from Roy Palmer's book The Rambling Soldier which documents the life of the soldiers of the British Army from 1750 to 1900 through their writings and their songs. 

This song comes from the Napoleonic wars and according to the description in Roy Palmer's book was popular at the time of Waterloo and remained in oral circulation for a century afterwards.

The first verse describes Napoleon's basic tactics, particularly his use of cannon in his major battles. 

There are a variety of versions of this song in circulation with a number of different verses and with other tunes.
