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.

[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.

The Lancastrian army was crushed by Neville; Ros was subsequently found hiding with lord Hungerford in a wood.
