We continued two hours in conference: a plan was formed, approved, and a certainty of success demonstrated; especially when I told him I had two horses waiting. We vowed eternal friendship; I gave him fifty ducats, and his debts, not amounting to more than two hundred rix-dollars, which he never could have discharged out of his pay.

He was to prepare four keys to resemble those of my dungeon; the latter were to be exchanged on the day of flight, being kept in the guard-room while the major was with General Walrabe. He was to give the grenadiers on guard leave of absence, or send them into the town on various pretences. The sentinels he was to call from their duty, and those placed over me were to be sent into my dungeon to take away my bed; while encumbered with this, I was to spring out and lock them in, after which we were to mount our horses, which were kept ready, and ride to Gummern. Every thing was to be prepared within a week, when he was to mount guard. We had scarcely formed our project before the sentinels called the major was coming; he accordingly barred the door, and the major passed to General Walrabe.

No man was happier than myself; my hopes of escape were triple; the mediation at Berlin, the mine I had made, and my friend the lieutenant.

When most my mind ought to have been clear, I seemed to have lost my understanding. I came to a resolution which will appear extravagant and pitiable. I was stupid enough, mad enough, to form the design of casting myself on the magnanimity of the Great Frederic! Should this fail, I still thought my lieutenant a saviour.

Having heated my imagination with this scheme, I waited the visitation with anxiety. The major entered, I bespoke him thus:

"I know, sir, the great Prince Ferdinand is again in Magdeburg.

Inform him that he may examine my prison, double the sentinels, and give me his commands, stating what hour will please him I should make my appearance on the glacis of Klosterbergen. If I prove myself capable of this, I then hope for the protection of Prince Ferdinand: and that he will relate my proceeding to the King, who may he convinced of my innocence."The major was astonished; the proposal he held to be ridiculous, and the performance impossible. I persisted; he returned with the sub-governor, Reichmann, the town-major, Riding, and the major of inspection. The answer they delivered was, that the Prince promised me his protection, the King's favour, and a release from my chains, should I prove my assertion. I required they would appoint a time;they ridiculed the thing as impossible, and said that it would be sufficient could I prove the practicability of such a scheme; but should I refuse, they would break up the flooring, and place sentinels in my dungeon, adding, the governor would not admit of any breaking out.

After promises of good faith, I disencumbered myself of my chains, raised my flooring, gave them my implements, and two keys, my friends had procured me, to the doors of the subterranean gallery.
