The battle of bosworth field 1485

After the murder of the young princes in 1483, loyal Yorkists began to look for a focus of opposition. A rebellion under Richard\'s former ally, the Duke of Buckingham, failed in 1483 and, after his execution, many older Yorkists fled abroad. Anti-Richard support gradually gravitated to the last Lancastrian claimant, Henry Tudor - hitherto largely unimportant. Richard\'s support narrowed, so when he faced a small invasion force at Bosworth Field in 1485, few magnates would fight for him.
