king penetrated with his barons into Mid Wales, while the pope and
archbishop excommunicated Llewelyn and put his lands under interdict.
Yet neither temporal nor spiritual arms were of avail against the
Welshman. Henry's only exploit in this, his second Welsh campaign, was
to rebuild Maud's Castle in stone. He withdrew, and in December agreed
to conclude a three years' truce, and procure Llewelyn's absolution.
Hubert once more bore the blame of his master's failure.

On July 9, 1228, Stephen Langton died. Despite their differences as to
the execution of the charters, his removal lost the justiciar a
much-needed friend. Affairs were made worse by the unteachable folly of
the monks of Christ Church. Regardless of the severe warning which they
had received in the storms that preceded the establishment of Langton's
authority, the chapter forthwith proceeded to the election of their
brother monk, Walter of Eynsham. The archbishop-elect was an ignorant
old monk of weak health and doubtful antecedents, and Gregory IX.
wisely refused to confirm the election. On the recommendation of the
king and the bishops, Gregory himself appointed as archbishop Richard,
chancellor of Lincoln, an eloquent and learned secular priest of
handsome person, whose nickname of "le Grand" was due to his tall
stature. The first Archbishop of Canterbury since the Conquest directly
nominated by the pope--for even in Langton's case there was a form of
election--Richard le Grand at once began to quarrel with the justiciar,
demanding that he should surrender the custody of Tunbridge castle on
the ground of some ancient claim of the see of Canterbury. Failing to
obtain redress in England, Richard betook himself to Rome in the spring
of 1231. There he regaled the pope's ears with the offences of Hubert,
and of the worldly bishops who were his tools. In August, Richard's
death in Italy left the Church of Canterbury for three years without a
pastor.
