Here he was joined by Caulaincourt, who had to inform him of the dissolution of the Congress at Chatillon, with the addition, that he had not received his instructions from Rheims, until the diplomatists had departed. Those subsequently despatched by Count Frochot, he had not received at all.
Meanwhile, Napoleon's cavalry commenced the proposed operations in the rear of the allies, and made prisoners some persons of consequence, who were travelling, as they supposed, in perfect security, between Troyes and Dijon. Among these was Baron Weissemberg, who had long been the Austrian envoy at the court of London. The Emperor Francis was nearly surprised in person by the French light troops. He was obliged to fly in a _drosky_, a Russian carriage, attended only by two domestics, from Bar-sur-Aube to Chatillon, and from thence he retreated to Dijon![28] Napoleon showed every civility to his prisoner, Weissemberg, and despatched him to the Emperor of Austria, to solicit once more his favourable interference. The person of the present King of France[29] (then Monsieur) would have been a yet more important capture, but the forays of the light cavalry did not penetrate so far as to endanger him.
On the 24th March, Napoleon halted at Doulevent, to concentrate his forces, and gain intelligence. He remained there also on the 25th, and employed his time in consulting his maps, and dictating new instructions for Caulaincourt, by which he empowered him to make every cession. But the hour of safety was past. Upon the morning of the 26th, Napoleon was roused by the intelligence, that the allies had attacked the rear of his army under Macdonald, near St. Dizier. He instantly hastened to the support of the maréchal, concluding that his own scheme had been successful, and that his retreat to the eastward had drawn after him the grand army of the allies. The allies showed a great number of cavalry with flying guns, but no infantry. Napoleon ordered an attack on them, in which the French were successful, the allies falling back after slight opposition. He learned from the prisoners, that he had been engaged, not with Schwartzenberg, but with Blucher's troops. This was strange intelligence. He had left Blucher threatening Meaux, and now he found his army on the verge of Lorraine.
