The Treason of Bartholomew de Badlesmere
He was indebted to the crown for numerous charters for fairs throughouthis
extensive manors; and he held the high office of steward of the householdfor
a great number of years; but notwithstanding his thus basking in thesunshine
of royal favor, his allegiance was not trustworthy, for joining thebanner of Thomas, Earl of Lancaster, and other discontented nobles ofthat period, he went into Kent without the king's permission; where,being well received, he put himself at the head of some soldiers from hiscastle at Ledes, and thence proceeded to Canterbury, with 19 knights,having linen jackets under their surcoats, all his esquires being inplate armor, and thus repaired to the shrine of St. Thomas, to theamazement of the good citizens. While Lord Badlesmere remained atCanterbury, John de Crumwell and his wife sought his lordship's aid, and, pledging himself to afford it, he hastened to Oxford, where the baronsof his party had been then assembled. In the meantime the King beingapprised of the baron's proceedings, dispatched the Queen to Ledes, andupon admission being denied her, the castle was regularly invested byAdomere de Valence, Earl of Pembroke, and John de Britannia, Earl ofRichmond, to whom it eventually surrendered, when Lord Badlesmere's wife,young son, and daughters, all falling into the hands of the besiegers,were sent prisoners to the Tower of London. The baron and his accomplicesafterwards were pursued by Edmund, Earl of Kent, and John de Warren, Earlof Surrey, and being defeated and taken prisoners at the battle ofBoroughbridge, his lordship was hanged, drawn, and quartered atCanterbury, and his head set upon a pole at Burgate. At the time of thebaron's execution upwards of ninety lords, knights, and others concernedin the same insurrection, suffered a similar fate in various parts of thekingdom. He married Margaret Clare, one of the daughters and co-heiressesof Thomas de Clare, 3rd son of Thomas de Clare, 2nd son of Richard deClare, Earl of Gloucester. His widow continued as a prisoner in theTower, until, through the influence of William Roos, Lord Roos, ofHamlake, and others, she obtained her freedom. Whereupon she went to thenunnery of Minoresses, outside of Adgate, in the suburbs of London. Shehad 2-shillings a day for her maintenance, to be paid by the sheriff ofEssex; she subsequently, however, obtained a large proportion of thedeceased lords' manors as her dowry.
