This is a rather large print of a drawing of the Battle of Bosworth Field. The Lancastrians are on the left side of this drawing. The White Rose side of the House of York is on the right side of this drawing.
Sir Walter Hungerford can barely be seen in the ranks of the Lancastrians, sort of hidden behind Simon Digby, but you can see his helmet which bears the crest of a garb and two sickles, and of course bits of the banner show the black and silver bars and plates. Also note that the Courtenay fellow has his horse draped with his arms quartered, the familiar gold field, three (red) torteaux with blue label of difference along with the blue lion on a gold field of his wife.
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, became the first English monarch of the Tudor dynasty by virtue of his victory at Bosworth Field. His opponent, Richard III, the last king of the House of York, was killed in the battle. The Battle of Bosworth Field marked the end of the Plantagenet dynasty, making it a defining moment of English and Welsh history.
