From same, p 92: "On July 15, 1262, the day after the kin
g sailed to
France, Earl Richard de Clare died. Two weeks later he wa
s buried at
Tewkesbury Abbey. The earl had not played a conspicuous rol
e in the baronial
movement since the settlement of 1261; he had been in ill h
ealth for some
months before his death, and rumors circulated that he ha
d been poisoned.
[Footnote by Altschul: "E.g., Dunstable, p. 219' *Annale
s Cambriae*, pp. 99-100, where "Gilbert" is wrongly given f
or "Richard." These chronicles have probably confused th
e earl's natural death with the alleged poison plot of 1258
."]" [Was Richard maybe poisoned at the instigation of Sim
on de Montfort or some of his allies?] Henry had settled w
ith the rebellious barons in 1261 (p 92). Richard de Clar
e had at first sided with the barons in the antiroyalist
movement which began in the summer of 1258 or thereabouts (
p 82-87), but
appears to have withdrawn support shortly after December 12
58 (p 87).
