HANOVER, SEPTEMBER 27th. Britannic Majesty, reduced to that frightful pinch, has at last given way. Treaty of Neutrality for Hanover; engagement again to stick one's puissant Pragmatic sword into its scabbard, to be perfectly quiescent and contemplative in these French-Bavarian Anti-Austrian undertakings, and digest one's indignation as one can. For our Paladin of the Pragmatic what a posture! This is the first of Three Attempts by our puissant little Paladin to draw sword;--not till the third could he get his sword out, or do the least fighting (even foolish fighting) with all the 40,000 he had kept on pay and subsidy for years back. The Neutrality was for Hanover only, and had no specific limit as to time. Opportunities did rise; but something always rose along with them,--mainly the impossibility of hoisting those lazy Dutch,--and checked one's noble rage. His Majesty has covenanted to vote for Karl Albert as Kaiser; even he, and will make the thing unanimous! A thoroughly check-mated Majesty. Passing home to England, this time in a gloomy condition of mind, shortly after these humiliations, he was just issuing from Osnabruck by the Eastern Gate, when Maillebois's people entered by the Western,--the ugly shoes of them insulting his kibes in this manner. And a furious Anti-Walpole Parliament, most perturbed of National Palavers, is waiting him at St. James's. Heavy-laden little Hercules that he is! Karl Albert lay at Linz for a month longer (till October 24th, six weeks in all); pausing in uncertainties, in a pleasant dream of victory and sovereignty; not pouncing on Vienna, as Friedrich urged on the French and him, to cut the matter by the root. He does push forward certain troops, Comte de Saxe with Three Horse Regiments as vanguard, ever nearer to Vienna; at last to within forty miles of it; nay, light-horse parties came within twenty-five miles. And there was skirmishing with Mentzel, a sanguinary fellow, of whom we shall hear more; who had got "1,000 Tolpatches" under him, and stood ruggedly at bay. Karl Albert has been sending out sovereign messages from Linz: Letters to Vienna;--one letter addressed "To the Arch-duchess Maria Theresa;" which came back unopened, "No such person known here." October 2d, he is getting homaged at Linz, by the STANDE of the Province,--on summons sent some time before,--many of whom attend, with a willing enough appearance; Kur-Baiern rather a favorite in Upper Austria, say some. Much fine processioning, melodious haranguing, there now is for Karl Albert, and a pleasant dream of Sovereignty at Linz: but if he do not pounce upon Vienna till Khevenhuller get it fortified? Khevenhuller is drawing home Italian Garrisons, gradually gathering something like an Army round him. In Khevenhuller's imperturbable military head, one of the clearest and hardest, there is some hope. Above all, if Neipperg's Army were to disengage itself, and be let loose into those parts?
