Capetian wet dreams

Taken me a while to track this down. Attached (first pic) is an entry from the Chronicle of Bury St Edmunds, describing the treason of Thomas Turberville in 1295.

This was one of the great scandals of the age. Thomas, a former household knight, had defected to the French and offered to raise a great rebellion in Wales and Scotland against Edward I. This would coincide with a full-scale French invasion of England. Once the British Isles were conquered - just like that, easy peasy - the French king, Philip le Bel, would reward Thomas by making him Prince of Wales. Philip would now be Emperor of the West, the stuff of Capetian wet dreams.

In the event Thomas was captured, interrogated and executed at Smithfield. I don't know anything about his ancestry or whether he had some kind of blood claim to the crown of Wales. Presumably he did.

Thomas had a competitor for the title in the shape of Madog ap Llywelyn, fifth cousin of Prince Llywelyn ap Gruffudd. Both seem to have regarded the removal of the senior branch of the House of Aberffrau as a vital first step: Madog served in the king's army against Llywelyn in 1277 (second pic) and Thomas served in the invasion of Gwynedd in 1282 (third pic).
