Walter Devereux (1411–1459)
Following the death of Edmund Mortimer, 5th Earl of March, on 18 January 1425, Richard, 3rd Duke of York inherited his estates along the Welsh Marches. This brought Walter Devereux into the retinue of the Duke, and he remained his loyal supporter throughout the War of the Roses. Devereux had been knighted by 22 September 1429 when he first represented Herefordshire in Parliament. He probably was in attendance on the Duke when he travelled with Henry VI to France for his coronation on 16 December 1429. On his return Devereux represented Herefordshire again in Parliament on 16 January 1430. He was listed on the subsidy rolls for Herefordshire of 12 January 1431 as holding his 1/3 of half a fee in Byford.
Walter Devereux, 7th Baron Ferrers of Chartley
In December 1460 Walter Devereux accompanied Edward, Earl of March, to Wales to raise an army to counter a Lancastrian rebellion led by the Tudors. On 30 December, Richard, 3rd Duke of York, was killed at the Battle of Wakefield, and a Lancastrian army moved south towards London. Devereux fought on behalf of Edward, now the 4th Duke of York, at his victory in the Battle of Mortimer's Cross on 2 February 1461, and commanded his left wing. He remained at the side of the future Edward IV on his advance from Gloucester to London. The Lancastrian army marching south was again victorious at the Second Battle of St Albans on 17 February, and recovered Henry VI here. On 3 March 1461, Walter Devereux was present at the council held at Baynard's Castle where it was resolved that Edward would be made King, and rode at his side to Westminster where Henry VI was deposed in absentia and Edward IV proclaimed King of England.
