Chapter X. -- CROWN-PRINCE GOES TO THE RHINE CAMPAIGN. The Kaiser--with Kehl snatched from him, the Rhine open, and Louis XV. singing TE DEUM in the Christmas time for what Villars in Italy had done--applied, in passionate haste, to the Reich. The Reich, though Fleury tried to cajole it, and apologize for taking Kehl from it, declares for the Kaiser's quarrel; War against France on his behalf; [13th March, 1734 (Buchholz, i. 131).]--it was in this way that Friedrich Wilhelm and our Crown-Prince came to be concerned in the Rhine Campaign. The Kaiser will have a Reich's-Army (were it good for much, as is not likely) to join to his own Austrian one. And if Prince Eugene, who is Reich's-Feldmarschall, one of the TWO Feldmarschalls, get the Generalship as men hope, it is not doubted but there will be great work on the Rhine, this Summer of 1734. Unhappily the Reich's-Army, raised from--multifarious contingents, and guided and provided for by many heads, is usually good for little. Not to say that old Kur-Pfalz, with an eye to French help in the Berg-and-Julich matter; old Kur-Pfalz, and the Bavarian set (KUR-BAIERN and KUR-KOLN, Bavaria and Cologne, who are Brothers, and of old cousinship to Kur-Pfalz),--quite refuse their contingents; protest in the Diet, and openly have French leanings. These are bad omens for the Reich's-Army. And in regard to the Reich's-Feldmarschall Office, there also is a difficulty. The Reich, as we hinted, keeps two supreme Feldmarschalls; one Catholic, one Protestant, for equilibrium's sake; illustrious Prince Eugenio von Savoye is the Catholic;--but as to the Protestant, it is a difficulty worth observing for a moment. Old Duke Eberhard Ludwig of Wurtemberg, the unfortunate old gentleman bewitched by the Gravenitz "Deliver us from evil," used to be the Reich's-Feldmarschall of Protestant persuasion;--Commander-in-Chief for the Reich, when it tried fighting. Old Eberhard had been at Blenheim, and had marched up and down: I never heard he was much of a General; perhaps good enough for the Reich, whose troops were always bad. But now that poor Duke, as we intimated once or more, is dead; there must be, of Protestant type, a new Reich's-Feldmasschall had. One Catholic, unequalled among Captains, we already have; but where is the Protestant, Duke Eberhard being dead? Duke Eberhard's successor in Wurtemberg, Karl Alexander by name, whom we once dined with at Prag on the Kladrup journey, he, a General of some worth, would be a natural person. Unluckily Duke Karl Alexander had, while an Austrian Officer and without outlooks upon Protestant Wurtemberg, gone over to Papacy, and is now Catholic. "Two Catholic Feldmarschalls!" cries the CORPUS EVANGELICORUM; "that will never do!"
