Two were killed and others wounded on this venture. In the afternoon, a drum was sent to the castle saying that General Goring and Langdale were routed, and that Cromwell, Fairfax and Rossiter were coming to the besiegers' assistance.

- 1483 - On 15th July 1483, Richard III, lord of Sandal, appointed the Duke of Buckingham as Lord High Constable of England, a higher rank than given to John Howard, Duke of Norfolk. Cornelius Aurelius, author of the early sixteenth-century account, ‘Divisiekroniek’, written in the Low Countries, claimed that Buckingham was responsible for the fate of Edward IV’s two sons, the noted ‘Princes in the Tower’. Aurelius claimed: ‘the Duke of Buckingham killed these children hoping to become king himself….he had read a prophecy about a future King Henry of England….and he believed himself to be this for he was called Henry. And some say..that this Henry…killed only one child and spared the other….and had him secretly abducted out of the country. This child was called Richard…..he came to Brabant to Lady Margaret his aunt…the widow of Duke Charles of Burgundy.’
