This submission did not altogether satisfy Napoleon. To his strength he added artifice; his suspicions still led him to covet the occupation of the fortresses, which he was ashamed not to leave in Frederick’s hands; he required the king to keep only 50 or 80 invalids in some, and desired that some French officers should be admitted into others; all of whom were to send their reports to him, and to follow his orders. His solicitude extended to every thing. “Spandau,” said he, in his letters to Davoust, “is the citadel of Berlin, as Pillau is that of Koenigsberg;” and French troops had orders to be ready to introduce themselves at the first signal: the manner he himself pointed out. At Potsdam, which the king had reserved for himself, and which our troops were interdicted from entering, his orders were, that the French officers should frequently show themselves, in order to observe, and to accustom the people to the sight of them. He recommended every degree of respect to be shown, both to the king and his subjects; but at the same time he required that every sort of arms should be taken from the latter, which might be of use to them in an insurrection; and he pointed out every thing of the kind, even to the smallest weapon. Anticipating the possibility of the loss of a battle, and the chances of Prussian vespers, he ordered that his troops should be either put into barracks or encampments, with a thousand other precautions of the minutest description. As a final security, in case of the English making a descent between the Elbe and the Vistula, although Victor, and subsequently Augereau, were to occupy Prussia with 50,000 men, he engaged by treaty the assistance of 10,000 Danes.
All these precautions were still insufficient to remove his distrust; when the Prince of Hatzfeld came to require of him a subsidy of 25 millions of francs to meet the expenses of the war which was preparing, his reply to Daru was, “that he would take especial care not to furnish an enemy with arms against himself.” In this manner did Frederick, entangled as it were in a net of iron, which surrounded and held him tight in every part, put between 20 and 30,000 of his troops, and his principal fortresses and magazines, at the disposal of Napoleon[2].
[Footnote 2: By this treaty, Prussia agreed to furnish two hundred thousand quintals of rye, twenty-four thousand of rice, two million bottles of beer, four hundred thousand quintals of wheat, six hundred and fifty thousand of straw, three hundred and fifty thousand of hay, six million bushels of oats, forty-four thousand oxen, fifteen thousand horses, three thousand six hundred waggons, with harness and drivers, each carrying a load of fifteen hundred weight; and finally, hospitals provided with every thing necessary for twenty thousand sick. It is true, that all these supplies were to be allowed in deduction of the remainder of the taxes imposed by the conquest.]
