Meanwhile, the Russians and Prussians had resolved upon an attempt to raise the siege of Dantzig: a considerable body came to attack the French camp before the fort of Weichelsmunde. They were repulsed, after a furious combat, by the aid of the reinforcements which had arrived to succor Marshal Lefebvre; and the attempts of the English corvettes to re-victual the town were equally unsuccessful. A previous attack of the Swedes upon Stralsund had brought about no definite result, and their general, Essen, had been constrained to conclude an armistice. Dantzig capitulated at last, on the 26th of May, without having undergone the assault which the French soldiers loudly demanded. As early as the 22nd, Napoleon had written to Marshal Lefebvre: "I authorize Marshal Kalbreuth to go out under the ordinary regulations, wishing to give this general an especial proof of esteem; however, the capitulation of Mayence cannot be taken as a basis, as the siege was less advanced than that of Dantzig now is. I allowed, at the time, an honorable capitulation for General Wurmser, shut up in Mantua; I wish to accord one more advantageous to General Kalbreuth, taking a middle position between that of Mayence and that of Mantua."
All the French corps d'armée occupied entrenched camps, prudently defended against the attacks of enemies; they were suffering from the rigors of the winter, and the large stores of wine found in Dantzig were an important resource for the soldiers. The attempts at mediation by Austria had failed; the campaign of 1809 was being prepared; everywhere the grass was springing up in the fields, affording necessary sustenance for the horses; the wild swans were reappearing in flocks upon the shores of the Passarge. The Emperor Napoleon had fixed upon the 10th of June for the resumption of hostilities.
The Russians forestalled it: Alexander had sent his guard to General Benningsen. "Brothers, uphold honor!" said the young emperor to his soldiers as they began the march. "We will do everything that is possible," cried the troops: "adieu, master!" Already Benningsen was advancing against the corps of Ney, who occupied the advanced posts, but the clever and prudent arrangements of Napoleon had prepared the retreat of his lieutenants; without disorder and without weakness, always victoriously fighting, Marshal Ney fell back upon Deppen; two other attacks upon the bridges of Lanutten and Spanden were likewise repulsed. The concentration of the French corps d'armée began to be effected near Saafeldt, when General Benningsen changed all of a sudden his plan of campaign: passing from the offensive to the defensive, he decided to repass the Alle, in order to protect the entrenched camp of Heilsberg, and by the same movement the town of Königsberg, the last refuge of the resources of Prussia. The retreat of the Russians commenced on the evening of the 7th of June.
Napoleon followed them with almost the whole of his army; the detachments of the vanguard and rearguard had more than once been engaged in partial combats when, on the evening of the 10th of June, the French army debouched before the entrenched camp of Heilsberg strongly supported by the banks of the Alle. Napoleon followed the left bank, seeking to forestall the enemy at the confluence of the Alle and the Pregel, in the hope of seizing Königsberg before the place could be succored. Murat and Davout were already threatening the city.
It was the supreme feature in the genius of Napoleon, that an indomitable perseverance in wisely calculated projects did not exclude the thunderbolts of a marvellous promptitude in resolution and combinations. Uncertainty and want of foresight reigned, on the contrary, in the military councils of the Russians. General Benningsen, formerly in the attitude of attack, now compelled to engage in a defensive march, and projecting the defence of Königsberg, thought it all of a sudden necessary to protect himself against an attack in flank. He crossed the Alle under the eyes of the French, and meeting them on the left bank of the river, he advanced towards the corps of Marshal Lannes, whom the emperor had sent against Domnau; a strong Russian detachment drove from Friedland the regiment of French hussars, who had established themselves there. The whole Russian army attacked Marshal Lannes, who had just collected a few reinforcements. It was to judge badly of the able prudence of the Emperor Napoleon, to hope to encounter a single corps of his grand army: Lannes held out till mid-day upon the field of battle with heroic skill; he sent meanwhile express after express to the emperor, who arrived at a gallop, his face radiant with the anticipation of the joys of victory. "It is the 14th of June," said he, "the anniversary of Marengo; it is a lucky day for us."
Napoleon and his staff had preceded the march of the troops; Lannes and his soldiers recovered their forces in the presence of the invincible chief who had so many times led them to victory. "Give me only a reinforcement, sire," cried Oudinot, whose coat was pierced with bullets, "and although my grenadiers can do no more, we will cast all the Russians into the water."
This was the aim of the emperor as well as of his soldiers; and the positions which General Benningsen had taken, concentred in a bend of the river, rendered the enterprise practicable. The day was advanced, and a few of the generals had been wishing to put off the battle till the morrow. "No!" said Napoleon; "one does not surprise the enemy twice in such a blunder." Then sweeping with his telescope the masses of the enemy grouped before him, he quickly seized the arm of Marshal Ney. "You see the Russians and Friedland," said he; "the bridges are there—there only. March right on before you; enter into Friedland; take the bridges, whatever it may cost, and do not disquiet yourself about what shall take place on your right, or your left, or in your rear. That concerns us—the army and me."
When Marshal Ney had set out, marching to danger as to a festival, the emperor turned towards Marshal Mortier and said, "That man is a lion."
Upon the field of battle, where he had just arrived in face of the enemy, who appeared hesitating and troubled, Napoleon dictated his orders, which he caused to be delivered to all his lieutenants. The troops continued to arrive; all the corps formed again at the posts which had been assigned to them. The emperor checked the impatience of his generals. "The action," he told them, "will commence when the battery posted in the village of Posthenen shall commence to fire." It was half-past five when the cannon at last sounded.
Ney advanced towards Friedland under a terrible fire from the Russians; extricated by the cavalry of Latour-Marbourg, and protected by the artillery of General Victor, suddenly thrown in advance, the French columns had reached a stream defended by the imperial Russian guard. The resistance of these picked troops for a moment threw disorder into our lines, who fell back; when General Dupont, arriving with his division, broke the Russian guard. The French in pursuit of their enemies penetrated into Friedland. The city was in flames; the fugitives fled towards the bridges; a very small number had succeeded in reaching them when this only means of safety was snatched from them; the bridges were cut and set on fire when Marshal Ney took possession of the burning remains of Friedland. At the same moment the corps of General Gortschakoff, pressed by Marshals Lannes and Mortier, fighting valiantly in a position without egress, sought in vain to reconquer the city, and afterwards redescended the length of the river in the hope of finding fordable passages. Many soldiers were drowned, others succeeded in regaining the right shore. Almost the entire column of General Lambert succeeded in escaping. Night at length followed the long twilight; it was ten o'clock in the evening when the combat ceased. The victory was complete; the remains of the Russian army retired upon the Pregel without Napoleon being able again to encounter them. They soon afterwards gained the Niemen. Meanwhile Marshal Soult had occupied Königsberg, evacuated by Generals Lestocq and Kaminsky. The King of Prussia possessed nothing more than the little town of Memel.
