Prince Karl, some weeks ago, at Heilbronn, joined his Rhine Army, which had gathered thither from the Austrian side, through Baiern, and from the Hither-Austrian or Swabian Winter-quarters; with full intent to be across the Rhine, and home upon Elsass and the Compensation Countries, this Summer, under what difficulties soever. Karl, or, as some whisper, old Marshal Traun, who is nominally second in command, do make a glorious campaign of it, this Year;--and lift the Cause of Liberty, at one time, to the highest pitch it ever reached. Here, in brief terms, is Prince Karl's Operation on the Rhine, much admired by military men:-- "STOCKSTADT, JUNE 20th, 1744. Some thirty and odd miles north of Mannheim, the Rhine, before turning westward at Mainz, makes one other of its many Islands (of which there are hundreds since the leap at Schaffhausen): one other, and I think the biggest of them all; perhaps two miles by five; which the Germans call KUHKOPF (Cowhead), from the shape it has,--a narrow semi-ellipse; River there splitting in two, one split (the western) going straight, the other bending luxuriantly round: so that the HIND-head or straight end of the Island lies towards France, and the round end, or cow-LIPS (so to speak) towards native Teutschland, and the woody Hills of the Berg-Strasse thereabouts. Stockstadt, chief little Town looking over into this Cowhead Island, lies under the CHIN: understand only farther that the German branch carries more than two-thirds of the River; that on the Island itself there is no town, or post of defence; and that Stockstadt is the place for getting over. Coigny and the French, some 40,000, are guarding the River hereabouts, with lines, with batteries, cordons, the best they can; Seckendorf, with 20,000 more ('Imperial' Old Bavarian Troops, revivified, recruited by French pay), is in his garrison of Philipsburg, ready to help when needed:"--not moulting now, at Wembdingen, in that dismal manner; new-feathered now into "Kaiser's Army;" waiting in his Philipsburg to guard the River there. "Coigny's French have ramparts, ditches, not quite unfurnished, on their own shore, opposite this Cowhead Island (ISLE DE HERON, as they call it); looking over to the hind-head, namely: but they have nothing considerable there; and in the Island itself, nothing whatever. 'If now Stockstadt were suddenly snatched by us,' thinks Karl;--'if a few pontoons were nimbly swung in?'
