Shortly after this regrettable incident, Oudinot having been ordered to leave Dvinaburg and go up the river to rejoin Ney and Montbrun, his army Corps took the same route as they had done, and passed the town of Drouia. The Marshal intended to encamp his force some three leagues further on, but he feared that the enemy might use the ford to send across large parties of men to harass the great convoy which trailed behind him, so he decided that while he made off into the distance, with the main body of the troops, he would leave behind a regiment of General Castex's brigade, in the position which had been occupied by General Saint-Genies, to watch the ford. As my regiment was on duty, there fell to it the dangerous task of remaining behind at Drouia, on their own, until the following morning. I knew that the greater part of Wittgenstein's force had gone up the river, but I could see that he had left behind, not far from the ford, two strong regiments of cavalry, a force more than sufficient to overcome me.
However much I might have wished to carry out the order to set up my bivouac on the spot used two days previously by Saint-Genies, this was impossible, for the ground was littered with more than two hundred bodies in a state of putrefaction, and to this major reason was linked another not less important. What I had seen and what I had learned about war had convinced me that the best means of defending a river against an enemy whose aim is not to establish himself on the bank which one occupies, is to keep the main body of one's troops well back from the river edge; firstly to have timely warning of the enemy's approach, and secondly, because, as it his intention to make a sudden raid and then retire smartly, he dare not go too far from the spot where he can cross back to the other side. So I settled the regiment half a league from the Dvina, on some slightly undulating ground. I left only some two-man sentinels on the bank, because, when it is purely a matter of observation, two men can see as much as a large picket. Several lines of troopers were placed one after the other between these sentinels and our bivouac, where, like a spider at the bottom of its web, I could be rapidly informed by these threads about what was going on in the area which it was my duty to guard. I had forbidden all fires and even the lighting of pipes, and had ordered complete silence.
The nights are extremely short in Russia in the month of July, but this one seemed very long to me, so afraid was I that I might be attacked during the hours of darkness by a force superior in strength to my own. Half of the men were in the saddle, the remainder were allowing their horses to graze but were ready to mount if given the signal. All seemed quiet on the opposite bank, when my Polish servant, who spoke Russian fluently, came to tell me that he had heard one old Jewish woman who lived in a nearby house say to another, "The lantern has been lit in the clock tower at Morki. The attack is going to begin." I had the two women brought to me, and questioned by Lorentz. They said that, as they were afraid of their village becoming a battleground for the two enemies, they had been alarmed to see the lamp lit in the bell tower of the church at Morki, which, the night before last, had been the signal for the Russian troops to cross the ford and attack the French camp.
Although I was prepared for any eventuality, this was a piece of very useful information. At once the regiment was on horse, sabres in their hands. The sentinels by the river and the string of horsemen stretched across the plain passed from man to man, in low voices, the orders to come back. Two of the boldest sous-officiers, Prud'homme and Graft, went with Lieutenant Bertin to see what the enemy was doing. He came back shortly to say that a large column of Russian cavalry was crossing the ford, and that already there were some squadrons on our side of the river; but seemingly taken aback at not finding us camped at the same place as Saint-Genies, they had halted, fearing, no doubt to go too far from their only means of retreat; then, having decided to go on, they were now approaching at a walk, and were not far off.
I immediately set fire to a huge haystack and to several barns which stood on some high ground, and by the light of the flames I could easily distinguish the enemy column, consisting of Grodno Hussars. I had with me about a thousand brave men, and with a cry of "Vive L'Emperor!" we charged at the gallop towards the Russians who, taken by surprise by this fierce and unexpected attack, turned tail and rushed in disorder to the ford. There they came face to face with a regiment of dragoons who, being part of their brigade, had followed them and were just emerging from the river. This resulted in the most fearful confusion which enabled our men to kill many of the enemy and take many horses. The Russians tried to recross the ford in a mob to escape from the fire which my men aimed at them from the bank and a number of them were drowned. Our surprise attack had so startled the enemy who had thought to find us asleep, that they put up no resistance, and I was able to return to our bivouac without having to regret the death or wounding of any of our number. The break of day disclosed the field of battle covered by some hundreds of dead or wounded Russians. I left the wounded in the care of the inhabitants of the village near which we had spent the night, and took to the road to rejoin Marshal Oudinot, with whom I caught up that same evening. The Marshal gave me a hearty welcome and complemented the regiment on their conduct.
2nd Corps continued its march up the left bank of the Dvina and in three days arrived opposite Polotsk. There we learned that the Emperor had at last left Wilna, where he had spent twenty days, and was heading for Vitepsk, a town of some size, which he intended to make his new centre of operations.
On quitting Wilna, the Emperor had left the Duc de Bassano as governor of the province of Lithuania, and General Hogendorp as military commander. Neither of these two officials was suited to organising the rear echelons of an army. The Duc de Bassano, a former diplomat and private secretary, knew nothing about administration, while the Dutchman Hogendorp, who spoke little French, and had no idea of our military regulations and customs, was not likely to have much success with those French who passed through Wilna or with the local nobility. So the resources available in Lithuania were of no help to our troops.
The town of Polotsk is situated on the right bank of the Dvina. Its houses are built of wood and it is dominated by a very large and splendid college, at that time occupied by the Jesuits, almost all of whom were French. It is surrounded by an earthwork fortification, having at one time undergone a siege during the war waged by Charles XII against Peter the Great. The corps commanded by Ney, Murat and Montbrun, in order to get from Drissa to Witepsk, had built a pontoon bridge across the Dvina opposite Polotsk, which they left for Oudinot's corps, which was going to take the road for St. Petersburg. It was from here that 2nd Corps took a different direction to that of the Grande Armee, which we did not see again until the following winter, at the crossing of the Beresina.
It would require several volumes to describe the manoeuvres and the battles of that part of the army which followed the Emperor to Moscow. I shall therefore limit myself to describing the salient events as they occur.
On the 25th of July, there took place near to Ostrovno an advance-guard action, in which our infantry were successful, but where several regiments of cavalry were too hastily engaged by Murat. The 16th Chasseurs was amongst this number, and my brother, who commanded a squadron, was captured. He was taken far beyond Moscow to Sataroff, on the Volga, where he joined Colonel Saint-Mars and Octave de Segur. They helped each other to bear the boredom of captivity, to which my brother was already accustomed, as he had spent several years in the prisons and hulks of Spain. The fortunes of war treated us both differently; Adolphe was captured three times but never wounded, while I was often wounded but never captured.
