Battle of Bosworth Field

On 22 August 1485, Henry Tudor's army of perhaps five thousand met Richard III's larger royal force on Ambion Hill in Leicestershire. The crucial defection of the Stanleys mid-battle, and Richard's reckless personal charge in an attempt to kill Henry himself, decided the outcome. Richard III became the last English king to die in battle; Henry VII was crowned on the field. The Plantagenet dynasty ended on the same hour the Tudor dynasty began.
