(_July_).--Instructions (by Sec. Bennet) to Thos. Parnell, to go to Dover Castle to deliver instructions, and assist in their execution, relative to a certain lady (the Countess of Uhlfeldt), who is not to be permitted to depart, whether she have a pass or not; but to be invited, or if needful compelled, to lodge at the castle, where the best accommodation is to be provided for her. It is suspected that her husband lies concealed in the kingdom, and will also try to pass with his lady, but he also is to be detained, and her servants also. _July 11._--Thos. Parnell to Williamson. 'Found the Countess (of Uhlfeldt) at Dover, and by the aid of the Lieut.-Governor sent the searcher to her inn, to demand her pass. She said she had none, not knowing it would be wanted. She submitted patiently to be taken to the castle, and lodged there till a message was sent to town. The Regent's gentleman, the bearer will give an account of all things.' When she came to the castle, the emissary of Petkum presented himself, by name Peter Dreyer. Then the Lieutenant said, 'It is the King of Danemarc who has ordered you to be arrested.' She asked the cause. He replied, 'You undoubtedly set out incognito from Danemarck.' She replied to this that the King of Danem... had given her husband leave of absence for a term of eighteen months, which had not yet expired. They ordered her boxes and those of the nobleman who accompanied her to be opened, and they took all the papers. Afterwards Dreyer spoke to her, and she asked him why she was treated thus? He said he did not know the real cause, but that he believed it was for the death of Fos, and that she was believed to have been the cause of his death. They always mentioned this to her, and no other cause. This double traitor Braten enacted the gallant, entertained her, made her speak English (as she was bolder in speaking this language than any other), for she had just begun to learn it well, having had a language-master in London. One day he told that they intended conducting her to Danemarck. She told him there was no need to send her to Danem...; she could go there very well by herself. He said, 'You know yourself what suits you; if you will not go there willingly, I will manage so that you may go to Flanders.' She did not see that this was feasible, even if he was willing; she spoke with him as to the means, saw that he did not satisfy her, and did not trust his conversation; as he was cunning, he made her believe that the King wished her to go secretly, and that he would take it all upon himself; that the King had his reasons why he did not wish to deliver her into the hands of the King of Danem....
