After the decisive battle of Touton, Henry VI. and his Queen retired to Scotland to watch the first favourable opportunity of seizing the sceptre from the house of York. Edward IV., anticipating the danger that might arise to his crown by an alliance between his rival, the exiled monarch, and the king of Scotland, determined to counteract the effects of such a connection by a stroke of policy. Aware of the disaffected disposition of some of the Scottish nobles, and northern and island chiefs, he immediately entered into a negotiation with John, Earl of Ross, and Donald Balloch, to detach them from their allegiance. On the 19th of October, 1461, the Earl of Ross, Donald Balloch, and his son John de Isle, held a council of their vassals and dependants at Astornish, at which it was agreed to send ambassadors to England to treat with Edward. On the arrival of these ambassadors a negotiation was entered into between them and the Earl of Douglas, and John Douglas of Balveny, his brother, both of whom had been obliged to leave Scotland for their treasons in the previous reign. These two brothers, who were animated by a spirit of hatred and revenge against the family of their late sovereign James II., warmly entered into the views of Edward, whose subjects they had become; and they concluded a treaty with the northern ambassadors which assumed as its basis nothing less than the entire conquest of Scotland. Among other conditions, it was stipulated that, upon payment of a specified sum of money to himself, his son, and ally, the Lord of the Isles should become for ever the vassal of England, and should assist Edward and his successors in the wars in Ireland and elsewhere. And, in the event of the entire subjugation of Scotland by the Earls of Ross and Douglas, the whole of the kingdom on the north of the Frith of Forth was to be divided equally between these Earls and Donald Balloch, and the estates which formerly belonged to Douglas between the Frith of Forth and the borders were to be restored to him. This singular treaty is dated London, 18th February, 1462.[158]
