In Philip Rogers' excellent book, "The Battle in Bossenden Wood" (OUP 1961), he mentions in a footnote a ballad composed about the event.

A deranged vintner from Truro, John Tom, had disappeared in 1837 while on a business trip, and reappeared in Kent as "Sir William Courtenay". Avoiding a sentence of transportation for perjury and released from incarceration as a lunatic, he gathered a band of followers with quasi-religious millenarian promises, and led them aimlessly around the North Kent countryside for a day, during which he killed a man who dared to stand up to him. Eventually the band was cornered by the militia, a skirmish followed, and Tom was killed, along with some of his followers and some soldiers. He was buried in an unmarked grave in Hernhill churchyard, while some of his surviving followers were transported to Australia.

The footnote says "...Julia de Vaynes, editor of a collection of Kentish broadsides, poems etc. printed in 1882 (The Kentish Garland),. In the index, under Courtenay (Vol. II, p. 900, she wrote..." (a criticism of the local vicar's failure to conduct a proper funeral ceremony).

Does anyone have access to this, or any other ballad about the event?
