Sunday, 20th August, Friedrich, with his small Army, hardly above 15,000 I should guess, arrived at Frankfurt-on-Oder: "his Majesty," it seems, "lodged in the Lebus Suburb, in the house of a Clergyman's Widow; and was observed to go often out of doors, and listen to the cannonading, which was going on at Custrin." [Rodenbeck, i. 347.] From Landshut hither, he has come in nine days; the swiftest marching; a fiery spur of indignation being upon all his men and him, for the last two days fierier than ever,--longing all to have a blow at those incendiary Russian gentlemen. Five days ago, the Russians, attempting blindly on the Garrison of Custrin, had burnt,--nothing of the Garrison at all,--but the poor little Town altogether. Which has filled everybody with lamentation and horror. And, listen yonder, they are still busy on the solitary Garrison of Custrin;--audible enough to Friedrich from his northern or Lebus Suburb, which lies nearest the place, at a distance of some twenty miles. Of Fermor's red-hot savagery on Custrin, it is lamentably necessary we should say something: to say much would he a waste of record; as the thing itself was a waste of powder. A thing hideous to think of; without the least profit to Fermor, but with total ruin to all the inhabitants, and to the many strangers who had sought refuge there. One interior circumstance is memorable and lucky to us. Artillery-Captain Tielcke happened to be with these people; had come in the train of "two Saxon Princes, serving as volunteers;" and, with a singular lucidity, and faithful good sense, not scientific alone, he illuminates these black Russian matters for such as have to do with them. Tielcke's Book of _Contributions to the Art of War_ [_Beytrage zur Kriege-Kunst und (ZUR) Geschichte des Krieges von 1756 bis 1763_ (six thin vols. 4to, with many Plates); cited above.] is still in repute with Soldiers, especially in the Artillery line; and indeed shows a sound geometrical head, and contains bits of excellent Historical reading interspersed among the scientific parts. This Tielcke, it appears, was a common foot-soldier, one of those Pirna 14,000 made Prussian against their will; but Tielcke had a milkmaid for sweetheart in those regions, who, good soul, gave him her generous farewell, a suit of her clothes, perhaps a pair of her pails; and in that guise he walked out of bondage. Clear away; to Warsaw, to favor with the King and others (being of real merit, an excellent, studious, modest little man); and here he now reappears, in a higher capacity; as articulate Eye-witness of the Custrin Business and the Zorndorf, among much other Russian darkness, which shall remain comfortably blank to us.
