Demoralised by the loss of its admiral and seriously short of food, the fleet returned to Plymouth. Thomas Howard, elder brother of Edward, was assigned the new Lord Admiral, and was set to the task of arranging another attack on Brittany. The fleet was not able to mount the planned attack because of adverse winds and great difficulties in supplying the ships adequately and the "Mary Rose" took up winter quarters in Southampton. In August the Scots joined France in war against England, but were dealt a crushing defeat at the Battle of Flodden on 1513. A follow-up attack in early 1514 was supported by a naval force that included the "Mary Rose", but without any known engagements. The French and English mounted raids on each other throughout that summer, but achieved little, and both sides were by then exhausted. By autumn the war was over and a peace treaty was sealed by the marriage of Henry's sister, Mary, to French king Louis XII.
