An actual quote from William of Malmesbury's Chronicle of the Kings of England, a near-contemporary account of this occurrence from the conquests of William the Conqueror: 

Quote

Favoured by God’s assistance, he [William] easily reduced the city of Exeter, when it had rebelled; for part of the wall fell down accidentally, and made an opening for him. Indeed he had attacked it with the more ferocity, asserting that those irreverent men would be deserted by God’s favour, because one of them, standing upon the wall, had bared his posteriors, and had broken wind, in contempt of the Normans.
