After the destruction of the bridge, some of the French whose retreat was thus cut off, jumped into the Elster in the hope of swimming across. Several of them succeeded in doing so, Marshal Macdonald being among them; but the greater number, including among others Prince Poniatowski, were drowned, because after crossing the river they were unable to climb the muddy bank, which was lined by enemy soldiers.
Those of our soldiers who were trapped in the town and its suburbs aimed only to sell their lives as dearly as possible. They barricaded themselves behind the houses and fought all day and part of the night, but when their ammunition was exhausted they were forced to retire into their improvised defences where they were nearly all slaughtered! The carnage did not end until two o'clock in the morning!…
The number of those massacred in the houses is given as 13,000, while 25,000 were taken prisoner. The enemy collected 250 cannons.
After describing in general the events which followed the battle of Leipzig, I shall now describe some of those which related particularly to my regiment and Sebastiani's cavalry corps to which it belonged. Seeing that we had for three consecutive days repelled the enemy attacks and maintained our positions on the field of battle, the men were greatly surprised and disgusted when, in the evening of the 18th, we learned that because of shortage of ammunition we were about to retreat. We hoped that at least(and that appeared to be the Emperor's intention) we would go no further than across the river Saale to the proximity of the fortress of Erfurt, where we could renew our stocks of ammunition and recommence hostilities. So we mounted our horses at eight in the evening on the 18th of October, and abandoned the battlefield on which we had fought for three days and where we left the bodies of so many of our gallant comrades.
We had hardly left our bivouac when we ran into some of the difficulties arising from the failure of the general staff to make any arrangements for the withdrawal of such a large body of troops. At every minute the columns, particularly the artillery and cavalry, were held up by the need to cross wide ditches, bogs, and streams over which it would have been easy to put small bridges! Wheels and horses sank into the mud and, the night being very dark, there was congestion everywhere; our progress was therefore extremely slow, even when we were in the open country, and often completely arrested in the streets of the suburbs and the town. My regiment which was at the front of the column formed by Excelmans' division, which led this wearisome march, did not reach the bridge at Lindenau until four in the morning on the 19th. When we had crossed over, we were far from foreseeing the appalling catastrophe which would occur in a few hours.
Day broke; the fine, wide road was covered by troops of all arms, which showed that the army would still be of considerable strength on arriving at the Saale. The Emperor passed… but as he galloped along the side of the marching column, he did not hear the cheers which usually greeted his presence!… The army was displeased with the little effort which had been made to secure its retreat since leaving the battlefield. What would the troops have said if they had known of the inadequate arrangements made at the Elster, which they had just crossed, but where so many of their comrades would lose their lives?
It was during a halt at Markranstadt, a little town some three leagues from Leipzig, that we heard the explosion of the mine which destroyed the bridge; but instead of being alarmed, we rejoiced, for we all believed that the fuse would not have been lit until after the passage of all our columns, and in order, then, to prevent that of the enemy.
During the few hours of rest which we had at Markranstadt, without being aware of the catastrophe which had occurred at the river, I was able to review our squadrons in detail and find out what losses we had suffered during the three days of conflict. I was dismayed! For they came to 149 men, of whom 60 were killed, among whom were two captains, three lieutenant and eleven N.C.O.s. A very large fraction of the 700 men with which the regiment had arrived on the battlefield on the morning of October the 16th. Nearly all the wounded had been hit by cannon-balls or grape-shot which, sadly, gave them little hope of recovery. My losses might have been doubled if I had not, during the battle, taken precautions to shield my regiment from cannon fire, as much as possible. This requires some explanation.
There are circumstances where the most humane of generals finds himself in the painful position of having to expose his troops openly to enemy fire; but it often happens that certain commanders deploy their men uselessly in front of enemy batteries, and take no steps to avoid casualties, although sometimes this is very easy, particularly for cavalry, who because of the rapidity of their movements can go swiftly to the point where they are required and take up the desired formation. It is when large masses of cavalry are involved on extensive battlefields that these measures of preservation are most required, and where, however, they are least employed.
At Leipzig, on the 16th of October, Sebastiani, commanding the 2nd Cavalry Corps, having placed his three divisions between the villages of Wachau and Liebert-Wolkwitz, and indicated to each divisional general roughly the position he should occupy, Exelman found himself placed on undulating ground intersected, as a result, by small ridges and hollows. The Corps formed a line of considerable length. The enemy cavalry, being a long way from us, could not take us by surprise. I took advantage of the hollows in the ground where our brigade was positioned to conceal my regiment which, though formed up and ready for action, saw the greater part of the day pass without losing a single man, for the cannon-balls went over their heads while neighbouring corps suffered considerable casualties.
