On taking the field Napoleon placed himself at the head of the Bavarians, with whom be opposed the enemy’s army before the arrival of his own troops.  As soon as they were assembled he published the following proclamation, which still further excited the ardour of the troops.

Soldiers—­The war of the third coalition is commenced.  The Austrian army has passed the Inn, violated treaties, attacked and driven our ally from his capital.  You yourselves have been obliged to hasten, by forced marches, to the defence of our frontiers.  But you have now passed the Rhine; and we will not stop till we have secured the independence of the Germanic body, succoured our allies, and humbled the pride of our unjust assailants.  We will not again make peace without a sufficient guarantee!  Our generosity shall not again wrong our policy.  Soldiers, your Emperor is among you!  You are but the advanced guard of the great people.  If it be necessary they will all rise at my call to confound and dissolve this new league, which has been created by the malice and the gold of England.  But, soldiers, we shall have forced marches to make, fatigues and privations of every kind to endure.  Still, whatever obstacles may be opposed to us, we will conquer them; and we will never rest until we have planted our eagles on the territory of our enemies!

In the confidential notes of his diplomatic agents, in his speeches, and in his proclamations, Napoleon always described himself as the attacked party, and perhaps his very earnestness in so doing sufficed to reveal the truth to all those who had learned to read his thoughts differently from what his words expressed them.

At the commencement of the campaign of Austerlitz a circumstance occurred from which is to be dated the fortune of a very meritorious man.  While the Emperor was at Strasburg he asked General Marescot, the commander-in-chief of the engineers, whether he could recommend from his corps a brave, prudent, and intelligent young officer, capable of being entrusted with an important reconnoitering mission.  The officer selected by General Marescot was a captain in the engineers, named Bernard, who had been educated in the Polytechnic School.  He set off on his mission, advanced almost to Vienna, and returned to the headquarters of the Emperor at the capitulation of Ulm.

Bonaparte interrogated him himself, and was well satisfied with his replies; but, not content with answering verbally the questions put by Napoleon, Captain Bernard had drawn up a report of what he observed, and the different routes which might be taken.  Among other things he observed that it would be a great advantage to direct the whole army upon Vienna, without regard to the fortified places; for that, once master of the capital of Austria, the Emperor might dictate laws to all the Austrian monarchy.  “I was present,” said Rapp to me, “at this young officer’s interview with the Emperor.  After reading the report, would you believe that the Emperor flew into a furious passion?  ‘How!’ cried he, ’you are very bold, very presumptuous!  A young officer to take the liberty of tracing out a plan of campaign for me!  Begone, and await my orders.’”
