Baron von Seckendorf enjoined Mr. Wraxall from the queen to return as soon as possible to Celle, where she hoped to be able to admit him to an audience. She likewise desired that he would then give, on being stopped at the gates, a French name, which she suggested, as by that means, on seeing the report of all strangers who arrived at Celle, which was brought to her every morning, she should be apprised of his return. It was settled that on Mr. Wraxall's next visit to Celle he should take care to arrive in the night, go round the city, and lodge at a little obscure inn, called the "Sandkrug," in one of the suburbs.
Having received this satisfactory answer from her Majesty, Mr. Wraxall left Celle immediately and proceeded to Hanover, where he remained two days. He then crossed a large portion of the Electorate to Harburg, and reached Hamburg on the evening of October 15, 1774. On the morning of the 17th he repaired to the place when Baron von Bülow had arranged to meet him. The latter affected not to notice him, and turning, Mr. Wraxall followed him through a number of streets, till they arrived on the ramparts of the city. There, upon a retired bastion, Mr. Wraxall delivered the baron the letter, whose seal and address he immediately recognised as those of the queen, saying, "Oui, bon, je reconnais bien cette écriture." Mr. Wraxall then related to him all the circumstances of his journey, the mode he employed to deliver his letter to the queen, and the subsequent interview with Baron von Seckendorf. The baron approved highly of all that had been done; promised to communicate the particulars, and the queen's reply to his associates; and requested Mr. Wraxall to hold himself in readiness to return to Celle.
During the next six days the couple contrived to meet several times, though in the meanwhile the baron made excursions into Holstein, in order to lay before his friends the state of the business, and to concert the most judicious means for carrying it on to the desired completion. On October 23, Mr. Wraxall received from him his instructions for his second journey to Celle. They were, as before, only verbal, and the agent was empowered to commit them to paper when he should arrive there, observing the same precautions in receiving them back. They were to the following effect:—
"That the Danish nobility were grateful for, and perfectly satisfied with, the answer made by her Majesty to their proposals, and that they should proceed, in consequence, to concert measures for executing at a proper time the intended revolution in her favour. That Baron von Bülow, in addition to his own name, and that of young Baron von Schimmelmann, was empowered to vouch for Count von Laurvig, his father-in-law, the viceroy of Norway, who was to secure that kingdom and its capital, Christiania, for the queen. That old Baron von Schimmelmann, though he refused to take any active part in the enterprise, or to risk by any overt act his safety and fortune, was sincerely attached to the cause. That the governor of Glückstadt, one of the most important places and fortresses in Holstein, was disposed to aid the queen. That Rendsburg, the key of the duchy of Schleswig, would open its gates, as the party had secret adherents in the garrison, who would declare themselves, when it should prove necessary.
"That their friends were numerous and powerful in the army, the navy, the guards, in the metropolis, and even about the person of the king himself. But, that they besought her Majesty to repose on the honour and assurances given by Baron von Bülow, as representing the party, and entreated her not to insist on the disclosure of their names—a disclosure which could be of little or no advantage or gratification to her, and which might be fatal to them. That they unanimously and earnestly requested her to write to the King of England immediately, and confide the letter to their agent, urging the indispensable necessity of his sending a minister to the court of Copenhagen, where there was then only a resident, and authorizing such minister to declare, at the time when the counter-revolution was being effected, that the King of Great Britain was acquainted with it, approved of it, and would maintain it with all his power.
"That, as considerable expenses must necessarily be incurred in conducting and executing a project of such magnitude and importance, they hoped that the King of Great Britain, if he approved of the attempt to restore his sister, would be graciously pleased to assist the persons engaged in her cause with some immediate pecuniary assistance. They besought the queen to recommend this object to her brother. That during the winter they would perform everything for striking the blow, and would, if the answer from England were favourable, proceed to execute it as soon in the ensuing spring as the two Belts should be free from ice, and the communication open between the island of Seeland and the mainland of Jütland.
"That they hoped her Majesty would be pleased to communicate to Baron von Bülow the tenor of her letter to the King of England, as on his reply, in a great measure, depended the progress and success of the enterprise. Baron von Bülow particularly enjoined Mr. Wraxall to ask the queen whether she would consent to quit Celle and repair to Altona in disguise, if such a step should at a future time be thought expedient or necessary."
Previous to Mr. Wraxall's departure from Hamburg, he agreed on a meeting with Baron von Bülow, on October 28, at a posthouse in the wood of Zährendorf, a solitary hamlet nearly equi-distant from Celle and Altona. It was settled, that on leaving Celle, Mr. Wraxall should repair to Zährendorf, en route to Holland, and that the baron, disguised as a dealer in goods, should go to the same posthouse, without any attendant. As two travellers, it would be easy to meet and to pass some hours together, in so unfrequented a place, during the night.
This matter adjusted, Mr. Wraxall set out on October 23rd, but, in order to elude suspicion from passing the same road so frequently, he took the Lüneburg road. Between three and four o'clock in the morning of the 26th he reached the gates of Celle, and, after making use of the name suggested by the queen, drove round to the little inn in the suburbs. Baron von Seckendorf having set out on that very morning to pay a visit to Hanover, Mr. Wraxall was obliged to send an express to him, acquainting him with his arrival, and requesting his immediate return. After which, Mr. Wraxall remained concealed in the inn the whole day, and employed himself in drawing up his despatch to her Majesty.
