Under the impression that he would be supported he descended boldly, on the 29th of August, towards Kulm from where, pushing enemy troops before him, he sought to reach Teplice; it is a certainty that if Mortier and Saint-Cyr had carried out the orders which they had been given, the Russian, Austrian, and Prussian forces stuck on the appalling roads, cut off from Bohemia and finding themselves attacked in front and in the rear, would have laid down their arms. Vandamme would have then been eulogised by the same people who have since blamed him.

However that may be, Vandamme arrived at Teplice on the morning of the 30th of August to be confronted by the division of Ostermann, one of the best of the Russian generals. Vandamme went confidently into the attack, as he saw, coming down from the heights of Peterwalde, and taking the route which he had taken the day previously, a body of troops which he took to be the armies of Mortier and Saint-Cyr, whose help the Emperor had promised him. But instead of friends, these newcomers were two large Prussian divisions commanded by General Kleist, and which, on the advice of Jomini, had passed between the corps of Mortier and Saint-Cyr without these two marshals taking any notice, such was the reluctance of Saint-Cyr to got to the aid of one of his colleagues. A reluctance which, on this occasion, spread to General Mortier. Neither of them budged and this at a time when their co-operation joined to the gallant efforts of Vandamme would have led to the total defeat of the enemy, whose columns of infantry, cavalry, artillery, and baggage were piled up in disorder in the narrow passes of the high mountains which lie between Silesia and Bohemia.

In place of the help he was expecting, General Vandamme saw appear the two divisions of General Kleist, which instantly attacked him. Vandamme, continuing to fight the Russians of Ostermann in front of Teplice, turned round his rear-guard to face Kleist, whom he attacked furiously, but although the enemy was weakening, the huge reinforcements which they recieved, bringing their strength to around 100,000 men as opposed to Vandamme's remaining 15,000, made him think, in spite of his courage and tenacity, that he should retire towards the corps of Mortier and Saint-Cyr, whom he believed to be close at hand in accordance with what Prince Berthier had written to him on the Emperor's instructions.

On their arrival at the pass of Telnitz, the French found it occupied by General Kleist's divisions, who completely blocked their passage; but nevertheless, our battalions, preceded by the cavalry of General Corbineau who, in spite of the rough, mountainous terrain, had insisted on remaining the advance-guard, fell on the Prussians with such ferocity that they overcame them and broke through the pass after taking all the enemy guns, from which they took away only the horses because of the bad state of the roads.

Any soldier will be aware that such a success could be won only at the cost of many casualties, and after this savage engagement the strength of 1st Corps was greatly reduced. However, Vandamme, completely surrounded by forces ten times more numerous than his own, refused to surrender and placing himself at the head of two battalions of the 85th, the only ones left to him, he hurled himself into the midst of the enemy in a fight to the death. But his horse having been killed, a group of Russians seized him and made him prisoner. It is said that he was brought before the Emperor Alexander and his brother, the Grand Duke Constantin, and was rash enough to exchange insults with them. He was then taken to Wintka, on the frontier of Siberia, and did not see his country again until after the peace of 1814.

The battle of Kulm cost 1st Corps 2000 men killed and 8000 made prisoner, amongst whom was their commanding general. The 10,000 who were left managed to fight their way through the enemy lines to join Saint-Cyr and Mortier. Those two generals had gravely failed in their duty by not pursuing the beaten enemy and instead stopping, Saint-Cyr at Reinhards-Grimme and Mortier at Pirna, from where they could hear the noise of the battle being fought by Vandamme.

It is surprising that, from nearby Dresden, Napoleon did not send one of his aides-de-camp to make certain that Saint-Cyr and Mortier had gone to the aid of Vandamme, as he had ordered. The two marshals, having failed to carry out their orders, should have been court-martialled, but the French army, overwhelmed by the enormous number of enemies which Napoleon had raised against it, had reached such a point of exhaustion that had Napoleon wished to punish all those who failed in their duty, he would have had to dispense with the services of almost all his marshals. He therefore did no more than reprimand Saint-Cyr and Mortier.

He had an increasing need to conceal his disasters, for it was not only at Kulm that his troops had suffered a reverse, but at all points of the immense line which they occupied.

(Subsequent historical research has made it quite clear that as Napoleon was in control of the operations the two marshals were entirely correct in waiting to receive his instructions, as they did not know to where he intended them to go. As for the order to support Vandamme with two divisions, it did not arrive until the 30th, that is to say at a time when the catastrophe had already occurred, and no blame can be attributed to the marshals.)
