This Day in History: 1317-04-21

Royal envoys visited Thomas of Lancaster, lord of Pontefract, at Donington between 21st April and 2nd May 1317, and again between 29th May and 12th June 1317. It may have been the latter embassy which delivered a writ of summons to the Earl to be at Newcastle on 8th July 1317 for a new campaign; was this summons intended as a final test of the Earl’s loyalty?
