Now, scarcely had she reascended the throne than Mary had restored to the Prior of St.Andrews the title of Earl of Mar, that of his maternal ancestors, and as that of the Earl of Murray had lapsed since the death of the famous Thomas Randolph, Mary, in her sisterly friendship for James Stuart, hastened to add, this title to those which she had already bestowed upon him.
But here difficulties and complications arose; for the new Earl of Murray, with his character, was not a man to content himself with a barren title, while the estates which were crown property since the extinction of the male branch of the old earls, had been gradually encroached upon by powerful neighbours, among whom was the famous Earl of Huntly, whom we have already mentioned: the result was that, as the queen judged that in this quarter her orders would probably encounter opposition, under pretext of visiting her possessions in the north, she placed herself at the head of a small army, commanded by her brother, the Earl of Mar and Murray.
The Earl of Huntly was the less duped by the apparent pretext of this expedition, in that his son, John Cordon, for some abuse of his powers, had just been condemned to a temporary imprisonment.

He, notwithstanding, made every possible submission to the queen, sending messengers in advance to invite-her to rest in his castle; and following up the messengers in person, to renew his invitation viva voce.
Unfortunately, at the very moment when he was about to join the queen, the governor of Inverness, who was entirely devoted to him, was refusing to allow Mary to enter this castle, which was a royal one.

It is true that Murray, aware that it does not do to hesitate in the face of such rebellions, had already had him executed for high treason.
This new act of firmness showed Huntly that the young queen was not disposed to allow the Scottish lords a resumption of the almost sovereign power humbled by her father; so that, in spite of the extremely kind reception she accorded him, as he learned while in camp that his son, having escaped from prison, had just put himself at the head of his vassals, he was afraid that he should be thought, as doubtless he was, a party to the rising, and he set out the same night to assume command of his troops, his mind made up, as Mary only had with her seven to eight thousand men, to risk a battle, giving out, however, as Buccleuch had done in his attempt to snatch James V from the hands of the Douglases, that it was not at the queen he was aiming, but solely at the regent, who kept her under his tutelage and perverted her good intentions.
Murray, who knew that often the entire peace of a reign depends on the firmness one displays at its beginning, immediately summoned all the northern barons whose estates bordered on his, to march against Huntly.
All obeyed, for the house of Cordon was already so powerful that each feared it might become still more so; but, however, it was clear that if there was hatred for the subject there was no great affection for the queen, and that the greater number came without fixed intentions and with the idea of being led by circumstances.
The two armies encountered near Aberdeen.

Murray at once posted the troops he had brought from Edinburgh, and of which he was sure, on the top of rising ground, and drew up in tiers on the hill slope all his northern allies.

Huntly advanced resolutely upon them, and attacked his neighbours the Highlanders, who after a short resistance retired in disorder.
