In February 1462 John's representatives concluded an agreement once referred to as the Treaty of Westminster-Ardtornish, that envisaged nothing less than the conquest and partition of Scotland. John agreed to pay homage to Edward in return for his help in obtaining all of Scotland north of the Forth. The treaty is a remarkably vague document considering the risks John was prepared to take. It says absolutely nothing about the nature, scale and timing of English support. But for Edward it was a brilliant diplomatic coup. He achieved maximum results at minimum expense, laying out only as much bait as necessary to create a political disturbance in northern Scotland.
