Atholl was the enemy of Frazer, a canting, astute, and unscrupulous ruffian. Queensberry conceived that in a letter given to him by Lovat he had irrefutable evidence against Atholl as a conspirator, and he allowed Lovat to return to France, where he was promptly imprisoned as a traitor. Atholl convinced Anne of his own innocence, and Queensberry fell under ridicule and suspicion, lost his office of Commissioner, and was superseded by Tweeddale. In England the whole complex affair of Lovat's revelations was known as "The Scottish Plot"; Hamilton was involved, or feared he might be involved, and therefore favoured the new proposals of the Courtiers and English party for placing limits on the prerogative of Anne's successor, whoever he might be. In the Estates (July 1704), after months passed in constitutional chicanery, the last year's Act of Security was passed and touched with the sceptre; and the House voted Supply for six months. But owing to a fierce dispute on private business--namely, the raising of the question, "Who were the persons accused in England of being engaged in the 'Scottish Plot'?"--no hint of listening to proposals for Union was uttered. Who could propose, as Commissioners to arrange Union, men who were involved--or in England had been accused of being involved--in the plot? Scotland had not yet consented that whoever succeeded Anne in England should also succeed in Scotland. They retained a means of putting pressure on England, the threat of having a separate king; they had made and were making military preparations (drill once a-month!), and England took up the gauntlet. The menacing attitude of Scotland was debated on with much heat in the English Upper House (November 29), and a Bill passed by the Commons declared the retaliatory measures which England was ready to adopt. It was at once proved that England could put a much harder pinch on Scotland than Scotland could inflict on England. Scottish drovers were no longer to sell cattle south of the Border, Scottish ships trading with France were to be seized, Scottish coals and linen were to be excluded, and regiments of regular troops were to be sent to the Border if Scotland did not accept the Hanoverian succession before Christmas 1705. If it came to war, Scotland could expect no help from her ancient ally, France, unless she raised the standard of King James. As he was a Catholic, the Kirk would prohibit this measure, so it was perfectly clear to every plain man that Scotland must accept the Union and make the best bargain she could.
