On the side of the York dynasty, German and Swiss mercenaries fought.
On June 16, 1487, the last great battle of the War of the Roses period was held in England. It was the Battle of Stoke, a small town in the English county of Nottinghamshire, not far from the famous Sherwood Forest. The forces of the heirs of the Lancaster dynasty were led in that battle by the then English King Henry VII, a member of the Tudor family. He had become King of England about two years earlier by defeating Richard III, leader of the York dynasty (symbol of the white rose), in the fateful Battle of Bosworth Field.
In the Battle of Stoke, Henry VII. he won again, destroying practically completely the forces of the York dynasty. For example, John de la Pole (Earl of Lincoln) and Sir Thomas FitzGerald of Laccagh were killed in that battle on the side of the York dynasty. On the side of the York dynasty fought German and Swiss mercenaries, led by Colonel Martin Schwartz (born in Augsburg). There were about two thousand of these mercenaries. The Yorkists wanted to appoint Lambert Simnel as King of England, but their defeat at Stoke solidified the reign of Henry VII. and his Tudor dynasty.
