"Each Captain shall take with him a little Cask of Vinegar; of which, as soon as the regiments get to Camp, he must give me reckoning, and I will then have him repaid. This Vinegar shall solely and exclusively be employed for this purpose, That in places where the water is bad, there be poured into it, for the soldiers, a few drops of the vinegar, to correct the water, and thereby preserve them from illnesses. "So soon as the regiment gets on march, the Women who have permission to follow are put under command of the Profoss; that thereby all plunderings and disorders may the more be guarded against. If the Captains and Officers take Grooms (JAGER) or the like Domestics, there can muskets be given to these, that use may be had of them, in case of an attack in quarters, or on march, when a WAGENBURG (wagon-fortress) is to be formed.... FRIEDRICH." [Preuss, ii. 6, 7.] SAME TO SAME (Confidential, this one). "POTSDAM, 24th August. ... "Make as if you were meaning to go into Camp at Halle. The reason why I stop you is, that the Courier from Vienna has not yet come. We must therefore reassure the Saxon neighborhood. ... I have been expecting answer from hour to hour; cannot suitably begin a War-Expedition till it come; do therefore apprise Your Dilection, though under the deepest secrecy. "And it is necessary, and my Will is, That, till farther order, you keep all the regiments and corps belonging to your Column in the places where they are when this arrives. And shall, meanwhile, with your best skill mask all this, both from the Town of Halle, and from the regiments themselves; making, in conformity with what I said yesterday, as if you were a Corps of Observation come to encamp here, and were waiting the last orders to go into camp." "FRIEDRICH." [Ib. ii. 7, 8.] And in regard to the Vienna Courier, and Friedrich's attitude towards that Phenomenon, read only these Two Notes:-- 1. FRIEDRICH TO THE PRINCE OF PRUSSIA AND THE PRINCESS AMELIA (at Berlin) POTSDAM, "25th August," 1756. "MY DEAR BROTHER, MY DEAR SISTER,--I write to you both at once, for want of time. I will follow the advice you are so good as give me; and will take leave of the Queen [our dear Mamma] by Letter. And that the reading of my Letter may not frighten her, I will send it by my Sister, to be presented in a favorable moment.
