Napoleon spent a weary day of waiting in Dueben, yawning and scribbling, but keeping his geographer and secretary in readiness. It was said at the time, and has since been repeated, that throughout this portion of the campaign Napoleon was not recognizable as himself: that he ruminated long when he should have been active; that he consulted when he should have given orders; that he was no longer ubiquitous as of old, but sluggish, and rooted to one spot. But it is hard to see what he left undone, his judgment being mistaken as it was. When rumors of Bernadotte's movements began to arrive, he dismissed the idea suggested by them as preposterous; when finally, on the twelfth, he heard that Bluecher was actually advancing to Halle, and no possible doubt remained, he gave instant orders for a march on Leipsic. Critics have suggested that again delay had been his ruin; but this is not true. An advance over the Elbe toward Berlin in search of the enemy would merely have enabled Bluecher and Bernadotte to join forces sooner, and have rendered their union with Schwarzenberg easier. No stricture is just but one: that Napoleon, knowing how impossible it was to obtain such exact information as he seemed determined to have, should have divined the enemy's plan, and acted sooner. The accurate information necessary for such foresight was not obtainable; in fact, it seldom is, and some allowance may be made if the general lingered before rushing into the "tube of a funnel," as Marmont expressed it. On the morning of the thirteenth, while the final arrangements for marching to Leipsic were making, came the news of Bavaria's defection. It spread throughout the army like wildfire, but its effect was less than might be imagined, and it served for the priming of a bulletin, issued on the fifteenth, announcing the approaching battle.
