Thomas had inherited the barony of Ros when he was barely four years old. His great uncle, Sir Robert Ros, knight, was deputed to perform the office of chamberlain to Archbishop Stafford, on the day of his installation at Canterbury; this office belonged to Lord Ros, from his tenure of the manor of Hethfield, in Kent. The fee for this service was the furniture of the room, and the basin and towel. The manor, and tenure on which it was held, came to the Ros family, from the marriage of an ancestor with Margaret Badlesmere.
Thomas Lord Ros was only eighteen years of age when he was put by the king into full possession of his father's estates. Having been faithful to King Henry VI of England throughout his disputed reign, he was rewarded with certain commercial privileges, consisting, chiefly, of an entire remission of the customary duties on exported wool. In 1456, he had permission to go on a pilgrimage, and in 1460, the king settled on him, as in part, a recompense for the expenses and losses incurred in his service, an annuity of £40, arising out of certain manors forfeited by the Earl of Salisbury.
By at least one near-contemporary account ("Whethamstead's Register"), in the same year he was part of the Lancastrian army which was victorious at the Battle of Wakefield.[3] In February 1461, he was one of the knights made after another Lancastrian victory at the Second Battle of St Albans by Edward of Westminster, Prince of Wales. Later that year he was with the king at York when news arrived of the Lancastrian defeat at the Battle of Towton, and he accompanied the king in his flight to Berwick.
As a loyal supporter of Henry VI, Ros was attainted in Parliament on 4 November 1461. He led a section of the Lancastrian army which attacked John Neville's army at the Battle of Hedgeley Moor on 25 April, where his men fled, and then took part in the Battle of Hexham on 15 May 1464. The Lancastrian army was crushed by Neville; Ros was subsequently found hiding with lord Hungerford in a wood. He was beheaded the next day at Newcastle for treason,[4] and the Ros lands were confiscated. Belvoir Castle was given to William, Lord Hastings.
