It had cost Leicester some years and much labor to climb to the summit of his greatness; his descent was rapid beyond the calculation of the most sanguine among his enemies.  He had hitherto enjoyed the cooeperation of the powerful earls of Derby and Gloucester; but, if he was too ambitious to admit of an equal, they were too proud to bow to a fellow-subject.  Frequent altercations betrayed their secret jealousies; and the sudden arrest and imprisonment of Derby, on a charge of corresponding with the royalists, warned Gloucester of his own danger.  He would have shared the captivity of his friends had he assisted at the great tournament at Northampton; but by his absence he disconcerted the plans of his enemy, and, recalling Mortimer and the exiles, unfurled the royal standard in the midst of his tenantry.  Leicester immediately hastened to Hereford with the King, the Prince, and a numerous body of knights.  To prevent the effusion of blood their common friends intervened; a reconciliation was effected, and four umpires undertook the task of reconciling their differences.  But under this appearance of friendship all was hollow and insincere.  Leicester sought to circumvent his adversary; Gloucester waited the result of a plan for the liberation of Edward, which had been concerted through the means of Thomas de Clare, brother to the Earl, and companion to the Prince.

When Leicester received the news of Edward’s escape, he conceived that the prince was gone to join the Earl Warenne, and William de Valence, who a few days before had landed with one hundred and twenty knights on the coast of Pembrokeshire.  Ignorant, however, of his real motions, he dared not pursue him; but issued writs in the King’s name, ordering the military tenants of the Crown to assemble at first in Worcester, and afterward in Gloucester.  To these he added circular letters to the bishops, accusing Edward of rebellion, and requesting a sentence of
