Battle of Stoke Field

The Battle of Stoke Field (16 June 1487) may be considered the last battle of the Wars of the Roses, since it was the last major engagement in which a Lancastrian king faced an army of Yorkist supporters. The Battle of Bosworth, two years previously, had established Henry on the throne. The Battle of Stoke Field was the decisive engagement in an attempt by leading Yorkists to unseat him in favour of the pretender Lambert Simnel.
