Execution of William, 1st Baron Hastings. He was not attainted and his widow Katherine was placed under Richard’s protection. With Hastings were arrested John Morton, Bishop of Ely, Thomas Rotherham, Archbishop of York, and Thomas Lord Stanley. The reasons and circumstances for his sudden execution remain controversial. Peter Hancock’s theory that it was because Richard discovered that Hastings knew about the precontract between Edward IV and Eleanor Talbot, but had kept it secret from him, is certainly interesting.
