John Savage (soldier) in the context of English invasion of Scotland (1482)

The Battle of Bosworth or Bosworth Field (/ˈbɒzwərθ/ BOZ-wərth) was the last significant battle of the Wars of the Roses, the civil war between the houses of Lancaster and York that extended across England and Wales in the latter half of the 15th century. Fought on 22 August 1485, the battle was won by an alliance of Lancastrians and disaffected Yorkists. Their leader Henry Tudor, Earl of Richmond, became the first Welsh monarch of England from the Tudor dynasty by his victory and subsequent marriage to the de facto Yorkist heiress, Elizabeth of York. His opponent Richard III, the last king of the House of York, was killed during the battle, the last English monarch to fall in battle. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it one of the defining moments of English history.

Richard's reign began in 1483 when he ascended the throne after his twelve-year-old nephew, Edward V, was declared illegitimate, likely at Richard’s instigation. The boy and his younger brother Richard soon disappeared, and their fate remains a mystery. Across the English Channel Henry Tudor, a descendant of the greatly diminished House of Lancaster, seized on Richard's difficulties and laid claim to the throne. Henry's first attempt to invade England in 1483 foundered in a storm, but his second arrived unopposed on 7 August 1485 on the south-west coast of Wales. Marching inland, Henry gathered support as he made for London. Richard hurriedly mustered his troops and intercepted Henry's army near Ambion Hill, south of the town of Market Bosworth in Leicestershire. Lord Stanley and Sir William Stanley also brought a force to the battlefield, but held back while they decided which side it would be most advantageous to support, initially lending only four knights to Henry's cause; these were: Sir Robert Tunstall, Sir John Savage (nephew of Lord Stanley), Sir Hugh Persall and Sir Humphrey Stanley. Sir John Savage was placed in command of the left flank of Henry's army.
