For example, it was through Bluecher's wilfulness that the moral advantage lay with Napoleon in the opening of the struggle. On July ninth Bernadotte, Frederick William, and the Czar had met at Trachenberg to lay out a plan of campaign. In this conference, which first opened Napoleon's eyes to the determination of the allies, Bluecher had secured for himself an independent command. The accession of Austria rendered the agreement of Trachenberg null, but Bluecher did not abandon his ambition. Impatient of orders or good faith, he broke into the neutral zone at Striegau on August fourteenth, apparently without any very definite plan. Napoleon, hearing that forty thousand Russians from this army were marching toward Bohemia, advanced from Dresden on August fifteenth, to be within reach of the passes of the Iser Mountains on the Upper Elbe, and halted at Zittau as a central point, where he could easily collect about a hundred and eighty thousand men, and whence, according to circumstances, he could either strike Bluecher, cut off the Russians, or return to Dresden in case of need. That city was to be held by Saint-Cyr. On August twentieth Bluecher reached the banks of the Bober at Bunzlau; owing to Napoleon's nice calculation, Ney, Marmont, Lauriston, and Macdonald were assembled on the other side to check the advance, he himself being at Lauban with the guard. Had Bluecher stood, the Russo-Prussians would have been annihilated, for their inferiority was as two to one. But the headstrong general did not stand; on the contrary, retreating by preconcerted arrangement behind the Deichsel, he led his antagonist to the false conclusion that he lacked confidence in his army.
