In 1447 he married
Anne, the six-year-old daughter of
Richard of York. However, in the
Wars of the Roses, he remained loyal to
Henry VI against the
Yorkists. He was imprisoned at
Wallingford Castle when York briefly seized power after the
First Battle of St Albans in 1455. In 1458 he participated in
the Love Day, an attempt at reconciliation between the rival factions. He was a commander at the Lancastrian victories at the
Battle of Wakefield in 1460 and the
Second Battle of St Albans in 1461, and in the decisive defeat at
Towton in 1461. He fled to Scotland after the battle, and then joined
Queen Margaret in her exile in France. He was
attainted in 1461, and his estates were given to his wife, who separated from him in 1464. During the brief period of Henry VI's restoration he was able to regain many of his estates and posts. At the
Battle of Barnet, Exeter commanded the Lancastrian left flank. He was badly wounded and left for dead, but survived. Afterwards he was imprisoned, and Anne divorced him in 1472. He "volunteered" to serve on Edward IV's
1475 expedition to France. On the return voyage he fell overboard and
drowned, his body being found in the sea between Dover and Calais, Fabyan saying "but how he drowned, the certainty is not known". However, Giovanni Panicharolla, the Milanese envoy to the Burgundian court, was told by
Duke Charles that the
King of England had given specific orders for the sailors to throw his former brother-in-law overboard. ==Family==
