Mary’s defenders have attributed her sorrow to the gloom of a captive, forced into a hated wedlock. De Silva assigned her misery to a galling conscience. We see the real reasons of her wretchedness, and to these we must add the most poignant, Bothwell’s continued relations with his wife, who remained in his Castle of Crichton. He, too, was ‘beastly suspicious and jealous.’ No wonder that she called for a knife to end her days, and told du Croc that she never could be happy again.

Meanwhile the Lords, from the first urged on by Kirkcaldy, who said (April 26) that he must avenge Darnley or leave the country, were banded, and were appealing to Elizabeth for help, which she, a Queen, hesitated to lend to subjects confederated against a sister Queen. Kirkcaldy was the dealer with Bedford, who encouraged him, but desired that the Prince should be brought to England. Robert Melville dealt with Killigrew (May 27). Bothwell, to soothe the preachers, attended sermons, Mary invited herself to dinner with her reluctant subjects; the golden font, the christening gift of Elizabeth, was melted down and coined for pay to the guard of musketeers (May 31). Huntly asked for leave to go to the north. Mary replied bitterly that he meant to turn traitor, like his father. This distrust of Huntly is clearly expressed in the Casket Letters.[200] On May 30, Mary summoned an armed muster of her subjects. On June 6, Lethington carried out his deferred scheme, and fled to the Lords. On the 7th, Mary and Bothwell retired to Borthwick Castle. On June 11, the Lords advanced to Borthwick. Bothwell fled to Dunbar.[201] The Lords then retired to Dalkeith, and thence, on the same night, to Edinburgh. Thither Mary had sent a proclamation, which is still extant, bidding the citizens to arm and free her, not from Bothwell, but from the Lords. An unwilling captive would have hurried to their protection. The burgesses permitted the Lords to enter the town. Mary at once, on hearing of this, sent the son of Lady Reres to the commander of Edinburgh Castle, bidding him fire his guns on the Lords. He disobeyed. She then fled in male apparel to Dunbar, Bothwell meeting her a mile from Borthwick (June 11). On June 12, the Lords seized the remains of the golden font, and the coin already struck. On the 13th, James Beaton joined Mary and Bothwell at Dunbar, and found them mustering their forces. He returned, with orders to encourage the Captain of the Castle, but was stopped.

Next day (14th) the Lords made a reconnaissance towards Haddington, and Atholl, with Lethington, rode into Edinburgh, at the head of 200 horse. Lethington then for three hours dealt with the Keeper of the Castle, Sir James Balfour, his associate in the band for Darnley’s murder. Later, according to Randolph, they opened a little coffer of Bothwell’s which had a covering of green cloth, and was deposited in the Castle, and took out the band. Was this coffer the Casket? Such coffers had usually velvet covers, embroidered. Lethington won over Balfour, who surrendered the Castle presently. This was the deadliest stroke at Mary, and it was dealt by him whose life she had just preserved.

Next day the Lords marched to encounter Bothwell, met him posted on Carberry Hill, and, after many hours of manœuvres and negotiations, very variously reported, the Lords allowed Bothwell to slip away to Dunbar (he was a compromising captive), and took Mary, clad unqueenly in a ‘red petticoat, sleeves tied with points, a velvet hat and muffler.’ She surrendered to Kirkcaldy of Grange: on what terms, if on any, is not to be ascertained. She herself in Nau’s MS. maintains that she promised to join in pursuing Darnley’s murderers, and ‘claimed that justice should be done upon certain persons of their party now present, who were guilty of the said murder, and were much astonished to find themselves discovered.’ But, by Nau’s own arrangement of his matter, Mary can only have thus accused the Lords (there is other evidence that she did so) after Bothwell, at parting from her, denounced to her Morton, Balfour, and Lethington, giving her a copy of the murder band, signed by them, and bidding her ‘take good care of that paper.’ She did ‘take good care’ of some paper, as we shall see, though almost certainly not the band, and not obtained at Carberry Hill.[202] She asked for an interview with Lethington and Atholl, both of whom, though present, denied that they were of the Lords’ party. Finally, after parting from Bothwell, assuring him that, if found innocent in the coming Parliament, she would remain his loyal wife, she surrendered to Kirkcaldy, ‘relying upon his word and assurance, which the Lords, in full Council, as he said, had solemnly warranted him to make.’ So writes Nau. James Beaton (whose narrative we have followed) merely says that she made terms, which were granted, that none of her party should be ‘invaded or pursued.’[203] Sir James Melville makes the Lords’ promise depend on her abandonment of Bothwell.[204]

Whatever be the truth as to Mary’s surrender, the Lords later excused their treatment of her not on the ground that they had given no pledge, but on that of her adhesion to the man they had asked her to marry. According to Nau, Lethington persuaded the Lords to place her in the house then occupied by Preston, the Laird of Craigmillar, Provost of Edinburgh. She asked, at night, for an interview with Lethington, but she received no answer. Next morning she called piteously to Lethington, as he passed the window of her room: he crushed his hat over his face, and did not even look up. The mob were angry with Lethington, and Mary’s guards dragged her from the window. On the other hand, du Croc says that Lethington, on hearing her cries, entered her room, and spoke with her, while the mob was made to move on.[205] Lethington told du Croc that, when Mary called to him, and he went to her, she complained of being parted from Bothwell. He, with little tact, told her that Bothwell much preferred his wife. She clamoured to be placed in a ship with Bothwell, and allowed to drift at the wind’s will.[206] Du Croc said to Lethington that he hoped the pair would drift to France, ‘where the king would judge righteously, for the unhappy facts are only too well proved.’ This is a very strong opinion against Mary. Years later, when Lethington was holding Edinburgh Castle for Mary, he told Craig that, after Carberry ‘I myself made the offer to her that, if she would abandon my Lord Bothwell, she should have as thankful obedience as ever she had since she came to Scotland. But no ways would she consent to leave my Lord Bothwell.’[207] Lethington’s word is of slight value.

To return to Nau, or to Mary speaking through Nau, on June 16 Lethington did go to see her: ‘but in such shame and fear that he never dared to lift his eyes to her face while he spoke with her.’ He showed great hatred of Bothwell, and said that she could not be allowed to return to him: Mary, marvelling at his ‘impudence,’ replied that she was ready to join in the pursuit of Darnley’s murderers: who had acted chiefly on Lethington’s advice. She then told him plainly that he, Morton, and Balfour had chiefly prevented inquiry into the murder. They were the culprits, as Bothwell had told her, showing her the signatures to the murder band, when parting from her at Carberry. She reminded Lethington that she had saved his life. If Lethington persecuted her, she would tell what she knew of him. He replied, angrily, that she would drive him to extremities to save his own life, whereas, if matters were allowed to grow quiet, he might one day be of service to her. If he were kept talking, and so incurred the suspicion of the Lords, her life would be in peril. To ‘hedge,’ Lethington used to encourage Mary, when she was in Loch Leven. But he had, then, no ‘assurance’ from her, and, on a false alarm of her escape, mounted his horse to fly from Edinburgh.[208] Thus greatly do the stories of Mary and of Lethington differ, concerning their interview after Carberry. Perhaps Mary is the more trustworthy.

On June 17, 1567, John Beaton wrote to his brother, Mary’s ambassador in Paris. He says that no man was allowed to speak to Mary on June 16, but that, in the evening, she asked a girl to speak to Lethington, and pray him to have compassion on her, ‘and not to show himself so extremely opposed to her as he does.’[209] Beaton’s evidence, being written the day after the occurrences, is excellent, and leaves us to believe that, in the darkest of her dark hours in Scotland, insulted by the populace, with guards placed in her chamber, destitute of all earthly aid, Mary found in extreme opposition to her the man who owed to her his lands and his life.

And why was Lethington thus ‘extremely opposed’? First, Mary, if free, would join Bothwell, his deadly foe. Secondly, he knew from her own lips that Mary knew his share in Darnley’s murder, and had proof. While she lived, the sword hung over Lethington. He, therefore, insisted on her imprisonment in a place whence escape should have been impossible. He is even said to have advised that she should be secretly strangled. Years later, when time had brought in his revenges, and Lethington and Kirkcaldy were holding the Castle for Mary, her last hope, Lethington explained his change of sides in a letter to his opponent, Morton. Does Morton hate him because he has returned to the party of the Queen? He had advised Morton to take the same course, ‘being assured that, with time, she would recover her liberty (as yet I have no doubt but she will). I deemed it neither wisdom for him nor me to deserve particular ill will at her hands.’ This was a frank enough explanation of his own change of factions. If ever Mary came to her own, Lethington dreaded her feud. We shall see that as soon as she was imprisoned, Lethington affected to be her secret ally. Morton replied that ‘it was vain in Lethington to think that he could deserve more particular evil will at Mary’s hands than he had deserved already.’[210]

Lethington could not be deeper in guilt towards Mary than he was, despite his appearance of friendship. The ‘evil will’ which he had incurred was ‘particular,’ and could not be made worse. In the same revolution of factions (1570-73) Randolph also wrote to Lethington and Kirkcaldy asking them why they had deserted their old allies, Morton and the rest, for the Queen’s party. ‘You yourselves wrote against her, and were the chiefest causes of her apprehension, and imprisonment’ (at Loch Leven), ‘and dimission of her crown.... So that you two were her chiefest occasion of all the calamities, as she hath said, that she is fallen into. You, Lord of Lethington, by your persuasion and counsel to apprehend her, to imprison her, yea, to have taken presently the life from her.’[211] To this we shall return.

When we add to this testimony Mary’s hatred of Lethington, revealed in Nau’s MS., a hatred which his death could not abate, though he died in her service, we begin to understand. Sir James Melville and Throckmorton were (as we shall see) deluded by the ‘dulce manner’ of Lethington. But, in truth, he was Mary’s worst enemy, till his bolt was shot, while hers remained in her hands. Then Lethington, in 1569, went over to her party, as a charge of Darnley’s murder, urged by his old partisans, was hanging over his head.
