James III., King of Scotland, saw, not without misgiving, that his two brothers, the Duke of Albany and the Earl of Mar, were greatly beloved by his subjects; and this feeling was soon changed into one of positive hate, thanks to the whisperings of certain evil counsellors who were about his person. These wretches, well knowing the feeble nature they had to deal with, threw the King into a very sickness of terror with impossible stories of his brothers’ design against his crown and life.
The Earl of Mar, they told him, had obtained a positive assurance from certain sorcerers that his royal kinsman would die by the hand of a near relation, and they brought a sorcerer of their own to the palace to say that there was a lion in Scotland which would be torn in pieces by its own whelps. This was enough for the king; his cowardly spirit was frightened into energy and decision, and he ordered the arrest of his brothers. Albany was thrown into Edinburgh Castle, but the fate of Mar was determined on at once. He was suffocated in a bath, according to some historians; or, according to others, bled to the last drop of his blood.
Albany was in great danger of the same miserable lot, but he had friends both in France and in Scotland who were resolved not to let him perish without making an effort to save his life. They were not long in forming their plans. A little sloop sailed into Leith Roads with a cargo of Gascony wines, of which two small casks were sent as a present to the captive prince. The governor of the castle allowed them to be taken into the chamber in which his prisoner was confined, and when the duke came to dip into them, he found in one a ball of wax, containing a letter urging him to escape and make his way to the water-side, where he would find the little vessel waiting for him. In the other cask there was a coil of rope, which would enable him to drop from the walls of his prison to the rock on which the castle stands. His faithful chamberlain, who shared his captivity, promised to aid him in the enterprise.
The main point was to make sure of the captain of the guard. Albany, therefore, invited this officer to sup with him under the pretext of wishing to have his judgment on the wine. The invitation was accepted, and the captain, having as usual posted his men with due circumspection, led three of them into the duke’s room with him, and took his place at table.
