[Mary was a prisoner in Lochleven from 17th June 1567 to 2nd May 1568. The chief events of her captivity were her compulsory abdication on 24th July, the coronation of her infant son on the 29th of the same month, and the proclamation of the Earl of Murray as Regent on August 22nd. Her escape was preceded by at least one unsuccessful attempt. Murray visited Mary in Lochleven, and was by her asked to undertake the Regency, according to a letter from Throgmorton to Elizabeth, 20th August 1567 (in "Foreign Calendar," and in Keith's "History," vol. ii. p. 737).] Illustration: LOCHLEVEN CASTLE. ... Croc, who was French Ambassador in Scotland, has passed here on his way to France, and there is nobody now representing his King. _THE CASKET LETTERS_ The Ambassador here assures me that the King (of France) has in his favour both those who have assembled to detain the Queen (of Scots) and those who are against them, and has their signatures promising to keep up the friendship and alliance that the country has had with his predecessors. For this reason the King had proceeded in such a way as not to lose the support of the one side by taking up the cause of the other, but he could not avoid giving his aid to the Queen, whose adversaries assert positively that she knew she had been concerned in the murder of her husband, which was proved by letters under her own hand, copies of which were in his possession. [This is the earliest known reference to the Casket Letters.] _Guzman de Silva to the King, from London_, July 26. _Spanish State Papers._ Four days ago the preacher and confessor of the Queen of Scotland arrived here. He is a Dominican Friar, a Frenchman named Roche Mameret, and was at the Council of Trent.... He is much grieved at events in Scotland, and the imprisonment of the Queen, but more than all at the marriage with Bothwell, since he already has a wife.... He assured me that those who had risen against the Queen had not been moved by zeal to punish the King's murder, as they had been enemies rather than friends of his; nor in consequence of the marriage, as they had been all in favour of it, and had signed their names to that effect without exception, either lay or clerical, apart from the Earl of Murray, but their sole object had been a religious one, as they thought the Queen, being a Catholic, might settle religion in a way not to their liking. _ELIZABETH'S INTERVENTION_ _Queen Elizabeth to Sir Nicholas Throgmorton, in Scotland_, July 27, 1567. _Keith's History_, p. 702. You shall plainly declare unto them {the lords}, that if they shall determine anything to the deprivation of the Queen their sovereign lady of her royal estate, we are well assured of our own determination, and we have some just and probable cause to think the like of other Princes of Christendom, that we will make ourselves a plain party against them, for example to all posterity.
