Folville was summoned with horses and arms to a Military Council before the King's teenage
son and
Lieutenant of England held at
Rochester, Kent in September 1297, a few days before the English defeat at the
Battle of Stirling Bridge. John was ordered to muster at
Newcastle Upon Tyne for service against the Scots in December.
King Edward soon returned from his expedition to
Flanders and took charge of matters in Scotland and gained revenge at the
Battle of Falkirk the next summer. In 1299 Folville helped defend
Edinburgh Castle and was again summoned in June 1301 to join the King in his two-pronged attack which aimed to capture the whole of Scotland. Folville served as
MP for Rutland in 1298 and 1301 and as
MP for Leicestershire from 1300 to 1306. In 1304 he was accused of breaking into the home of William Hubert of Teigh and carrying away charters and
muniments but appears to have been excused as in 1306 he was appointed as a commissioner to enquire into progress on the building of a prison in
Leicester. In December 1309 he was appointed as a Justice of Leicestershire to receive complaints of violations of the
Statute of Stamford. Folville died in 1310 and an inquisition held found that he owned Ashby Folville for the service of two
Knight's fees. Folville's wife Alice outlived him but found herself in trouble when she was imprisoned in
Lincoln prison in September 1332, perhaps in relation to some of her sons' activities. ==Family==
