Bothwell offered single combat to any of the Confederate Lords. William Kirkcaldy accepted the challenge, but Bothwell would not fight him as he was merely a baron. He also refused Murray of Tullibardine, and then Lord Lindsay. It was hot and Queen Mary's supporters had nothing to drink. The day dragged on. Two of Bothwell's supporters, Edmund Blackadder and the laird of Wedderburn, understanding that Bothwell was intending to leave, made their apologies to the Queen and rode away. In response to an oath made by the rebel Lords, Queen Mary agreed to surrender to Kirkcaldy. He led her horse by the bridle down from the hill, while Bothwell rode off to Dunbar Castle with 25 horsemen. A drawing of the battlefield sent to London with a newsletter survives and gives a schematic idea of the events.
