at court attending all the great state occasions at home and abroad until his death; in 1511 he entertained Henry VIII at Harrowden. It was as a soldier and diplomat, however, that he made his mark. Given the important command at Guisnes, he distinguished himself during the Tournai campaign in 1513 and then in the missions (he had had some earlier experiences in negotiating, chiefly with Burgundy) to the French King about the English withdrawal and the several royal marriage treaties. Later, he was one of the devisers of the Field of the Cloth of Gold. His sister, Joan, had also benefited from the change of dynasty: she entered the royal household, became governess to Henry VII's daughters and married successively Sir Richard Guildford and the father of Sir Nicholas Poyntz, Sir Anthony Poyntz. Vaux was a natural candidate for election to Parliament, although in the absence of so many returns for the early Tudor period he is known to have been a Member only in 1515 when he and Sir John Hussey took a memorandum on certain Acts from the Commons up to the Lords. Presumably, he sat for his own shire on this occasion as he was afterwards appointed to the Northamptonshire commission for the subsidy which he had helped to grant. Missions to France On 4 September 1514, Vaux with his second wife Anne Green were part of the delegation tasked with delivering Princess Mary, the king's sister, to Abbeville in France to be married to King Louis XII of France. He also was present with his second wife Anne Green at the Field of the Cloth of Gold in 1520 where he attended upon the King and Queen Catherine of Aragon. He was joined by Sir Thomas Parr, his wife Maud Green, and his brother Sir William Parr of Horton.

The wedding took place most likely after the 1485 Battle of Bosworth when Henry Tudor (later King Henry VII) defeated Richard III. The union was most likely planned to secure the allegiance of the FitzHugh family to the new Tudor dynasty as Henry VII's wife, Elizabeth of York, was a granddaughter of Cecily
