When the time came for us to re-cross the Elbe and enter the territory of the Confederation of the Rhine, the Emperor, before removing his troops from Poland and Prussia, wanted to facilitate a return to the offensive by leaving strong garrisons in the fortresses which could assure the crossing of the Vistula, the Oder and the Elbe, such as Thorn, Stettin, Magdeberg, Danzig, Dresden, etc.
This major decision on the part of the Emperor may be looked at in two ways. So it has been praised by some knowledgeable military observers and condemned by others.
The first party say that the need to provide a place of rest and safety for the numerous sick and wounded, which the army brought back from Russia, compelled the Emperor to occupy these fortresses, which, in addition, could store a massive amount of military equipment and foodstuffs. They add that these fortresses hindered enemy movements and by investing them, the enemy reduced the number of troops which could be actively employed against us; and finally that if the reinforcements which Napoleon was bringing from France and Germany enabled him to win a battle, the possession of the forts would help to ensure a new conquest of Prussia, which would bring us to the banks of the Vistula and force the Russians to return to their country.
In reply to this it is claimed that Napoleon weakened his army by breaking it up into so many scattered units who could not give each other mutual assistance; that it was not necessary to compromise the security of France in order to save a some thousands of sick and wounded, very few of whom would return to active service, and of whom nearly all died in the hospitals. It was also said that the regiments of Italians, Poles, and Germans from the Confederation of the Rhine, which the Emperor mingled with the garrisons in order to lessen the requirement of French units, would not be much use; and in fact almost all the foreign troops fought very badly and ended up by going over to the enemy. Finally it was claimed that the occupation of the forts gave very little trouble to the Russian and Prussian armies, which, after blockading them with an observation force, could continue their march towards France. Which is what actually happened.
I find myself in agreement with latter of these two opinions, because it is evident that the forts could be of use to us only if we overcame the Russian and Prussian armies, which was a reason for concentrating our disposable manpower rather than dispersing it.
It might be said that as the enemy would no longer have to blockade the forts, they would thus have an increase in their manpower to match ours. But this is not so, for the enemy would have to leave strong garrisons in the forts which we abandoned, while we could make use of the men which were at present immobilised. I may add that the defence of these useless forts deprived the army in the field of the services of a number of experienced generals, among others, Marshal Davout, who alone was worth several divisions. I accept that during a campaign one must leave behind several brigades to guard places on which the safety of a country depends, such as Metz, Lille, and Strasbourg, in the case of France, but the forts situated on the Vistula, the Oder, and the Elbe, two or three hundred leagues from France, were of only conditional importance, that is to say dependent on the success of our army in the field. When this did not come about, over eighty thousand men whom the Emperor had left in those garrisons in 1812 were obliged to surrender.
The position of France in the first months of 1813 was extremely critical, for in the south our armies in Spain had suffered some very serious reverses due to the weakening of their strength by the continual withdrawal of regiments, while the English ceaselessly sent reinforcements to Wellington, who had fought a brilliant campaign during 1812, and had captured Cuidad-Rodrigo, Badajoz, and the fort of Salamanca, had won the battle of Arapiles, occupied Madrid and now threatened the Pyrenees.
In the north, the numerous battle-hardened soldiers whom Napoleon had led into Russia had nearly all died in action or of cold and starvation. The still-intact Prussian army had just joined the Russians, and the Austrians were on the point of following their example. Finally, the sovereigns, and more importantly, the people of the Germanic Confederation, stirred up by the English, were wavering in their allegiance to France. The Prussian Baron Stein, an able and enterprising man, took this opportunity to publish a number of pamphlets in which he appealed to all Germans to shake off the yoke of Napoleon and regain their liberty. This appeal was readily received, as the passage, the accommodation, and the maintenance of the French troops who had occupied Germany since 1806 had occasioned great expense, to which was added the confiscation of English merchandise, as a result of Napoleon's continental blockade. The Confederation of the Rhine would have defected if the rulers of the various states of which it was composed had decided to listen to the wishes of their subjects; but none of them dared budge, so ingrained was their habit of obedience to the French Emperor, and so great their fear of seeing him arrive at any moment, to head the considerable forces which he was organising with such speed and building up constantly in Germany.
The greater part of the French nation still had the greatest confidence in Napoleon. Those who were well-informed blamed him, no doubt, for having the previous year led his army to Moscow, and in particular for having awaited the winter there, but the mass of the people, who were used to considering the Emperor as infallible and had no notion of the events of this campaign nor of the losses suffered by our men, saw only the glory which the occupation of Moscow reflected on our arms, and were more than willing to give the Emperor the means to heap victories round his eagles. Every department and every town gave patriotic gifts of horses, though the numerous levies of conscripts and money soon cooled this enthusiasm. Nevertheless, the nation complied with reasonably good grace, and battalions and squadrons seemed to rise out of the ground, as if by some enchantment. It was remarkable that after all the levies of conscripts which had been made over the last twenty years, we had never recruited a finer body of men. There were several explanations for this.
To begin with, each of the eight hundred departments which then existed had, for several years, maintained a company of so-called departmental infantry, a sort of praetorian guard for the Prefects, who made a point of selecting men of a high physical standard for this duty. These men never left the principal towns of the department, where they were very well housed, fed, and clad, and as they had very few duties to perform, they were able to build up their physical strength, for most of them led this life for six or seven years, during which time they were exercised regularly in the handling of arms, and in marches and manoeuvres. They lacked only the "baptism of fire" to become complete soldiers. These companies, depending on the importance of the department, were of 150 to 250 men. The Emperor sent them all to the army, where they were absorbed into the line regiments.
