It was with Kaunitz that Friedrich's real difficulties lay. Privately, in the course of this Summer, Kaunitz, by way of preparation for "mediating a Turk-Russian Peace," had concluded his "subsidy Treaty" with the Turk, ["6th July, 1771" (Preuss, iv. 31; Hermann; &c. &c.).]--Treaty never ratified, but the Piastres duly paid;--Treaty rendering Peace impossible, so long as Kaunitz had to do with mediating it. And indeed Kaunitz's tricks in that function of mediator, and also after it, were of the kind which Friedrich has some reason to call "infamous." "Your Majesty, as co-mediator, will join us, should the Russians make War?" said Kaunitz's Ambassador, one day, to Friedrich. "For certain, no!" answered Friedrich; and, on the contrary, remounted his Cavalry, to signify, "I will fight the other way, if needed!" which did at once bring Kaunitz to give up his mysterious Turk projects, and come into the Polish. After which, his exorbitant greed of territory there; his attempts to get Russia into a partitioning of Turkey as well,--("A slice of Turkey too, your Czarish Majesty and we?" hints he more than once),--gave Friedrich no end of trouble; and are singular to look at by the light there now is. Not for about a twelvemonth did Friedrich get his hard-mouthed Kaunitz brought into step at all; and to the last, perpetual vigilance and, by whip and bit, the adroitest charioteering was needed on him. FEBRUARY 17th, 1772, Russia and Prussia, for their own part,--Friedrich, in the circumstances, submitting to many things from his Czarina,--get their particular "Convention" (Bargain in regard to Poland) completed in all parts, "will take possession 4th June instant:" sign said Convention (February 17th);--and invite Austria to join, and state her claims. Which, in three weeks after, MARCH 4th, Austria does;--exorbitant abundantly; and NOT to be got very much reduced, though we try, for a series of months. Till at last:--
