On the right of the French original line of advance, Schwartzenberg had no sooner learned that the Emperor was totally defeated, and his army irretrievably dispersed, than, in the quality of a mere auxiliary, he thought himself no longer entitled to hazard a single Austrian life in the quarrel. There was an armistice concluded between the Austrians and Russians, by the terms of which they agreed to manœuvre as at a game of chess, but not to fight. Thus, when the Russians should gain such a position, as in actual war would have given them an advantage, the Austrians were under the engagement to retreat; and the campaign resembled nothing so much as a pacific field-day, in which two generals in the same service venture upon a trial of skill. Schwartzenberg, by his manœuvres, protected the French corps under Regnier as long as possible, obtained good terms for Warsaw, and gained for Regnier three days advantage, when at last he ceased to cover the place. Having thus protected his allies to the last, he retired into the Austrian territories; and although Regnier was finally overtaken and surprised at Khalish, it could not be imputed to Schwartzenberg's desertion of him, but to his own making too long a halt to protect some Polish depôts. The relics of Regnier's army, such at least as fled into the Austrian territories, were well received there, and afterwards restored to their own banners. Still the alliance with Austria, which in one sense had cost Napoleon so dear, was now dissolved, and his right wing totally dissipated by the defection of his allies. On the left wing matters had no better, or rather, they had a much worse appearance. [Sidenote: PRECARIOUS STATE OF MACDONALD.]
