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.
