"Oliver Cromwell had certainly this afflatus. One that I knew was at the battle of Dunbar, told me that Oliver was carried on with a Divine impulse; he did laugh so excessively as if he had been drunk; his eyes sparkled with spirits. He obtain’d a great victory; but the action was said to be contrary to human prudence. The same fit of laughter seized Oliver Cromwell just before the battle of Naseby; as a kinsman of mine, and a great favourite of his, Colonel J. P. then present, testified. Cardinal Mazerine said, that he was a lucky fool."
