OXLANC-09N Four Lancastrian Billmen, The Retinue of John DeVere, 13th Earl of Oxford
The Battle of Bosworth (or Bosworth Field) was the last significant battle of the Wars of the Roses, the civil war between the Houses of Lancaster and York that raged across England in the latter half of the 15th century. Fought on 22 August 1485, the battle was won by the Lancastrians. Their leader Henry Tudor, Earl of Richmond, by his victory became the first English monarch of the Tudor dynasty. His opponent, Richard III, the last king of the House of York, was killed in the battle. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it a defining moment of English and Welsh history.
