Sir Rhys ap Thomas KG (1449–1525) was a Welsh soldier and landholder who rose to prominence during the Wars of the Roses, and was instrumental in the victory of Henry Tudor at the Battle of Bosworth. He remained a faithful supporter of Henry and was rewarded with lands and offices in South Wales. Some sources claim that he personally delivered the death blow to King Richard III at Bosworth with his poleaxe.[1][2]
