What can all this have to do with Prince Henry you may ask?
A great deal, we answer. For these bonfires all over England on the Fifth of November, commemorate an event in James the First's reign which had a great effect on our young hero's mind.
Certain persons in England, who hated King James for his hard treatment of the Roman Catholic party, resolved to take the law into their own hands. They thought that if the king, Prince Henry, and the Parliament could be destroyed at one blow, they might take possession of Prince Charles and Princess Elizabeth, bring about a revolution and put the government into the hands of the Roman Catholics who would be helped by Spain. Robert Catesby was the chief of the conspirators; and for eighteen months he and a small band of desperate men worked in the utmost secrecy at their hideous scheme. The day chosen for its accomplishment was the fifth of November, 1605, the day on which Parliament met at Westminster. Everything was in readiness. Thirty-six barrels of gunpowder (not fifty-two as the Hampshire rhyme has it) were stored beneath the Parliament House. And Guido Fawkes, a daring adventurer, was in waiting in the cellar to set a light to them, and blow up King, Prince, and Parliament. But at the last moment, in spite of all their well-laid plans, in spite of all their wonderful secrecy, the plot leaked out. Lord Monteagle, a Roman Catholic Peer, received a mysterious warning from Tresham, one of the conspirators, whose courage failed him. Monteagle instantly told the Earl of Salisbury and the king. At midnight on the eve of the fifth, the cellars under the Parliament House were searched. There was Guido Fawkes, with touchwood and matches upon him, only waiting for the signal which was to be given him in a few hours. He was seized, dragged before the king and consigned to the Tower. The great heap of wood and coals in the cellar was torn down, and the barrels of gunpowder found beneath it. The conspirators fled. All Protestant England was roused to a frenzy of horror and dread at the discovery of such a fearful crime. The guilty men were chased from county to county, till at last all of them were either killed fighting, or captured and brought next year to the block. And thus ended the Gunpowder Plot. But its memory is still kept alive in England by the yearly bonfires and fireworks and Guy Fawkes processions of the Fifth of November.
