Richard was probably born in the later years of Richard II’s reign as the son of one of the leading landowners in Dorset. Like many of his peers, he sought to while away the time until he should come into his inheritance by seeking military glory on the battlefields of France. He is not known to have participated in the Agincourt campaign, and may thus have cut his teeth serving in Sir John Blount’s expeditionary force in July 1417.
In May 1421 Stafford indentured once more to serve in France for half a year, with a personal retinue of ten men-at-arms and 30 mounted archers,
Sir Richard now settled down in his native county, and before long began to take over some of his father’s public duties. In 1423 and 1425 he was returned to the Commons as knight of the shire for Dorset, taking the seat that his father had filled in all Parliaments but one since 1417. While sitting in the first of his two Parliaments Stafford was pricked sheriff of the double-bailiwick of Somerset and Dorset, thus serving out much of his parliamentary term in factual, if not literal, contravention of the statutory prohibition of the return of sheriffs. Sir Richard’s sudden substitution for his father in public life caught some men unawares, and even the clerk compiling the pipe roll for 1424 erroneously substituted Sir Humphrey’s name for that of his son at the head of the year’s account.
Nevertheless, Sir Richard was not yet ready to settle down for good to the management of his estates, and in the summer of 1426 he once more set out for France, this time in the retinue of Richard Beauchamp, earl of Warwick, with a personal following of 39 men-at-arms and 150 archers. With this contingent, Stafford was assigned to the garrison of St. James de Beuvron on the Breton border, under the captaincy of Sir Thomas Rempston†. They had not been established there for long when a Breton army, said to consist of 20,000 men, but probably much smaller, laid siege to the fortified town. The Bretons’ initial assault was successfully deflected by the 900 defenders, English and Norman, and 400 of the assailants were killed. The following night, Rempston, Stafford, and their fellow leaders made a daring sortie with a small party of men, burnt two mills around which 300 of the besiegers were encamped and killed between 60 and 80 of them. Eventually, after a final assault, in the course of which the Bretons had incurred heavy losses and Duke Arthur of Brittany had himself been wounded in the thigh, the French abandoned the siege. They withdrew in some disarray, leaving their guns and tents, and hotly pursued by a detachment of the defenders who claimed to have killed a further 2,500 men in the rout. The victory celebrations were made memorable by the 600 pipes of wine, as well as flour, bread, figs, raisins, eggs, butter and a large quantity of fish, which the Bretons had left behind.
It is uncertain whether Stafford was wounded in the fighting, but he appears not to have returned to England from this expedition. The precise date of his death is unknown, but he was dead by the autumn of 1427, when his executors (John Newburgh I*, Hugh Deverell, Henry Sherard* and the clerk Henry Blakemore) were being sued by the Crown for the arrears of an annuity which Stafford had failed to pay to Sir Henry Brounflete when sheriff of Somerset and Dorset three years earlier.
