 It is highly unlikely that Mary, Queen of Scots, would have spent the night before the Battle of Langside (1568) at Cathcart Castle or have watched the battle from a nearby hill called the Court Knowe.The Semples were supporters of Mary's enemies and would have captured her and put an end to her plans before the battle had started.Court Knowe is some 60m below the height of Langside village, where the battle took place, meaning Mary would not have been able to see what took place.
