Thomas was eventually released around 1427 in a prisoner exchange negotiated by his uncle, Cardinal Beaufort.
As an able male member of the Beaufort family, Thomas rejoined the fighting almost immediately.
He was granted the title Count of Perche in December 1427, his title being more a claim to land, rather than a recognized title since it was already held by the French Duke John II of Alençon.

During the 1430 royal coronation expedition of Henry VI, Thomas was granted a retinue of 128 soldiers and 460 archers.
