Just a couple of points.
First off, it turns out the conspirators overdid the thing, and there was enough gunpowder there to flatten half of London. Poor Guido wouldn't have reached his getaway boat and would likely have been killed.
It seems that Guido was no fool, as it is recorded that, when they put the rope round his neck, he deliberately jumped off the scaffold, breaking his neck and making sure he was dead before the drawing and quartering could happen.
Every time there's a conspiracy in English history, there's somebody called Catesby in the thick of it! That family are never happy, are they?
My lad and I have our Guy Fawks costumes ready. If any politician (probably Nigel Garbage) even whispers "England Prevails", we're all over it!
