In 1360, Chandos was created a knight banneret, which allowed him to hold a banner in battle. This came being made the Viscount of Saint-Sauveur by Edward III. This is contrary to the Life of the Black Prince, written by the Herald of John Chandos which suggested that Chandos was made a banneret immediately before the Battle of Najera in 1367. Nevertheless, on that occasion, Edward, the Black Prince of Wales, and Aquitaine at that time, merely unfurled the banner for Chandos as a mark of respect.
