And they were in fact not far from succeeding, had not a mistake happened.
Silberberg, and Wartha the southernmost, which stands upon the Neisse River (rushing out there into the plainer country), are each about seven or eight miles from Frankenstein, the Head-quarters; and there are relays of posts, capable of supporting one another, all the way from Frankenstein to each.

Friedrich rode to Silberberg first; examined the post, found it right; then rode across to Wartha, seven or eight miles southward; examined Wartha likewise; after which, he sat down to dinner in that little Town, with an Officer or two for company,--having, I suppose, found all right in both the posts.

In the way hither, he had made some change in the relay arrangements, which at first involved some diminution of his own escort, and then some marching about and redistributing: so that, externally, it seemed as if the Principal Relay-party were now marching on Baumgarten, an intermediate Village,--at least so the Pandour Captain understands the movements going on; and crouches into the due thickets in consequence, not doubting but the King himself is for Baumgarten, and will be at hand presently.

Principal relay-party, a squadron of Schulenburg's Dragoons, with a stupid Major over them, is not quite got into Baumgarten, when "with horrible cries the Pandour Captain with about 500 horse," plunges out of cover, direct upon the throat of it: and Friedrich, at Wartha, is but just begun dining when tumult of distant musketry breaks in upon him.

With Friedrich himself, at this time, as I count, there might be 150 Horse; in Wartha post itself are at least "forty hussars and fifty foot." By no means "nothing but a single adjutant," as the Myth bears.
The stupid Major ought to have beaten this rabble, though above two to one of him.
