John of Gaunt return for a large annual payment and the marriage of their daughter Catherine to John of Trastámara's son Henry. John left Portugal for Aquitaine, and he remained in that province until he returned to England in November 1389. This effectively kept him off the scene while England endured the major political crisis of the conflict between Richard II and the Lords Appellant, who were led by John of Gaunt's younger brother Thomas of Woodstock, Duke of Gloucester. Only four months after his return to England, in March 1390, Richard II formally invested Gaunt with the Duchy of Aquitaine, thus providing
John of Gaunt ships to be sold to pay off the debts of Sir Robert de Crull, who during the latter part of King Edward III's reign had been the "Clerk of the King's Ships", and had advanced monies to pay for the king's ships . During the Peasants' Revolt of 1381, John of Gaunt was far from the centre of events, on the March of Scotland, but he was among those named by the rebels as a traitor to be beheaded as soon as he could be found. The Savoy Palace was systematically destroyed by the mob and burned to the ground.
