An agreement between the English Queen and the Lords of the Congregation was drawn up (February 27), with scrupulous care to avoid the appearance of dictation and encroachment which had gathered all Scotland to Pinkie Cleugh eleven years before. It set forth that the English troops were entering Scotland for no other object than to assist the Duke of Chatelherault, the heir-presumptive to the throne, and the other nobles, to drive out the foreign invaders. They would build no fortress. There was no intention to prejudice Mary’s lawful authority. Cecil appears to have wanted to add something about “Christ’s true religion;” but Elizabeth struck it out. Circumstances might compel her to be the protector of foreign Protestants; but neither then nor at any other time did she desire to pose in that character.
A month later (March 28th) Lord Grey crossed the Border, and marched to Leith. The siege of that place proved to be tedious. The Lords of the Congregation gave very insufficient assistance; and, when an assault had been repulsed with heavy loss, the citizens of Edinburgh would not receive the wounded into their houses. At last, when food was running short in the town, an envoy from France arrived with power to treat on behalf of the Queen of Scots. Her mother, the Regent, had died during the siege. After much haggling a treaty was signed. No French troops were in future to be kept in Scotland. Offices of State were to be held only by natives. The government during Mary’s absence was to be vested in a Council of twelve noblemen; seven nominated by her and five by the Estates. Elizabeth’s title to the kingdoms of England and Ireland was recognised (July 1560).
Such was the Treaty of Edinburgh, or of Leith, as it is sometimes called, one of the most successful achievements of a successful reign. It was gained by wise counsel and bold resolve; and its fruits, though not completely fulfilling its promise, were solid and valuable. It was not ratified by Mary. But her non-ratification in the long-run injured no one but herself, besides putting her in the wrong, and giving Elizabeth a standing excuse for treating her as an enemy. England was permanently free from the menace of a disciplined French army in the northern kingdom. Nothing was settled in the treaty about religion. But this was equivalent to a confirmation of the violent change that had recently taken place; in itself a guarantee of security to England.
