This Day in History: 1321-01-10
The siege of royalist Tickhill Castle (whose constable was William de Aune) by Thomas of Lancaster, lord of Pontefract, in his rebellion against Edward II, provoked Edward to crush Lancaster finally. The siege had begun by 10th January 1321 and news of it was evidently brought to the king at Gloucester for, in the ten days that he was there, preparations were put in hand for a full-scale campaign. Lancaster’s siege was ultimately unsuccessful. A file of twenty letters under the privy and secret seals, dating from 14th September 1320 to 11th March 1322, shows the King constantly pressing Aune for news, enjoining the strictest secrecy, urging him to fortify his castle, and asking for full reports on the comings and goings of the barons in Yorkshire.
