Sir John Savage, KG, KB, PC (1444–1492), was an English knight of the Savage family, who was a noted military commander of the late 15th-century. Savage most notably fought at the Battle of Bosworth Field in 1485, where he commanded the left flank of the Tudor (Lancastrian) army to victory and is said to have personally slain the Duke of Norfolk in single combat. Earlier in the Wars of the Roses, Savage had been a supporter and friend of the Yorkist King Edward IV, fighting alongside him and helping him to victories at the Battle of Barnet in 1471 and the Battle of Tewkesbury later that same year, as well as joining the Duke of Gloucester's invasion of Scotland in 1482, where the Duke made him a Knight banneret. However, following the death of Edward, the Duke of Gloucester became the de facto ruler of England, dominating the short rule of his nephew Edward V, and then later de jure ruler after taking the throne as Richard III following the mysterious death of Edward. During Richard's reign the Savage family was viewed with suspicion, and Savage was one of the prominent figures who invited Henry Tudor (later Henry VII) to invade, a struggle which culminated in the Battle of Bosworth Field.
