Jessen appeared at the appointed hour, and heard that, beside Von Eickstedt, Colonel von Köller was also present. The gentlemen expressed their determination to overthrow Struensee, and the two colonels reckoned on the support of their regiments and of the artillery in doing so. A few days after, Colonel Eickstedt sent the ex-valet a message, through Beringskjold, to grant him an interview, which was to take place at the rooms of the latter. Jessen went, and the colonel proposed to him to go quietly to Fredensborg--where the queen dowager and her son were residing at the time--and inform them that an insurrection against Struensee was being prepared, for which he (Eickstedt), Colonel Köller, and other gentlemen had drawn up the plan. The queen and hereditary prince were invited to place themselves at the head of the anti-Struensee party, in order by their authority to prevent the excited populace from committing excesses on innocent persons. The queen dowager had already been fully prepared for the event by the forged document shown her by Suhm. She consulted with Guldberg, and declared her willingness to accept the proposal made to her. The party of the queen dowager was thus organized. Valet Jessen conveyed the good news to Copenhagen, and there performed from time to time the part of negociator between the conspirators at Fredensborg and those in the capital. In order to avoid notice, he made his reports in writing, and addressed his letters sometimes to his mother-in-law, the waiting-woman, Jacobi, at others to his little daughter, Juliana Maria Jessen, who was afterwards a celebrated poetess, and at that time was living with her grandmother. When the queen dowager returned to Copenhagen in November, the secret meetings of her party were held at the house of Abildgaard, chaplain of the Holmenschurch, close to the palace, whose wife was a relation of Beringskjold. The rectory had two entrances, from two different streets, and Jessen, who was thoroughly acquainted with the ins and outs of the Christiansborg Palace, offered the conspirators the most valuable aid at these secret meetings. He was also thoroughly conversant with the private staircases that led in the palace from the queen's apartments to those of the king and Struensee, so that it was eventually an easy matter for the conspirators to cut off all communication between the three parties most interested, at the moment when they carried out their enterprise. The outbreak of the conspiracy was settled for the night between January 16 and 17, 1772. On Thursday, the 16th, a _bal paré en domino_ was given in the palace theatre at Christiansborg, to which all nine rank-classes were admitted.
