Battle of Bosworth Field
After withdrawing from the battle, Oxford fled to France and participated in attacks on English ships, continuing his campaign against Yorkist rule. He was captured in 1473 after seizing St Michael's Mount, an island off the southwest coast of England. Twelve years later Oxford escaped from prison and joined Henry Tudor's fight against the Yorkists, commanding the Lancastrian army at the Battle of Bosworth Field in 1485.
