I think he was caught a bit north of where the big Tesco's is now, more up towards Tonyrefail near the Royal Mint (no English jokes please about 'The Hole with a Mint!)
The place is still known as 'Pant y Brad' (the hollow of the treachery) and a an old commemorative plaque used to be on the bridge there. Variations of the tale abound, but a monk from Penrhys Priory in the Rhondda was alleged to to have given him away. He had fled from the advance of his wife Queen Isabella (The She-Wolf of France) who had taken Roger Mortimer as her lover and Edward, with his boyfriend Huw Despenser the Younger, fled to Wales, staying five nights in Despenser's Caerphlly Castle, before fleeing further to Neath Abbey with his personal treasure. He left the there for some reason and came back eastwards - there is a story of him hiding up an oak tree at Llangynwyd nar Maesteg ( how many kings are alleged to hidden up oak trees?) Then he was caught near Tonyrefail and taken to Llantrisant Cstle, en route to Berkeley. The two Despensers, father and son, were hanged, drawn and quartered, Dad in Bristol and the son in Hereford, from a fifty foot scaffold.
If you want to read about the allegation that Edward survived and died in Italy, look up 'The Fieschi Letter ' on Wikipedia or read Ian Mortimer's controversial book.
Incidentally, in Victorian times, a doctor in Swansea treated an old lady and instead of a fee she gave him an old box, inside which was Edward Ii's marriage contract, perhaps left behind in Neath. It was in the Swansea Institution, but now in the Swansea Council Archives on Mumbles Road.
