Somehow he regained the king's favour, and in 1460 was appointed Keeper of Henry VI's "great Wardrobe". After Henry's defeat at Saint Albans in 1461, Vaughan, along with Philip Malpas and William Hatclyf, sailed for Ireland with Henry's treasury, but were captured by French pirates.

After Edward IV died in 1483, Vaughan was accompanying Edward V from Ludlow to London when the party was intercepted by the future King Richard III, then Duke of Gloucester.
