Richard was deeply perturbed by this affront to his royal prerogative, and from February to November 1387 went on a "gyration" (tour) of the country to muster support for his cause [REF].
Richard now had no choice but to comply with the appellants' demands; Brembre and Tresilian were condemned and executed, while de Vere and de la Polewho had by now also left the country[REF]were sentenced to death in absentia at the Merciless Parliament in February 1388 [REF].
