[Footnote 46: The reader will perhaps be gratified with a short topographical description of this fortress, and some details of this affair. The fortress of Modlin, which is in a pentagonal form, is situated sixteen miles from Warsaw, upon the right bank of the Vistula, at the junction of the Narew with the former river. Not far from this fortress, the small river Wkra also joins the Narew. The fortress is thus situated between three rivers. In addition to this peculiarity of its situation in regard to the rivers, its commanding elevation makes it a point of great strength. Opposite to it is the small town of Nowy-dwor, but this town is so low that it is commanded by the fortress, and it is besides too distant for the erection of batteries by which the latter could be bombarded with success. This post is very important in regard to tactics, and it is a key of position, to protect, or to act upon, all operations between the Narew and the Vistula. Marshal Diebitsch considering these circumstances, and seeing that an open attack was scarcely possible, was led to attempt negotiation. The letter sent by the marshal, was full of flattering language in regard to the heroism of the Polish army. He permitted himself, however, to say that it was to be regretted that such a degree of heroism was not exhibited in a better cause--that the brave Polish army was made a sacrifice of, by some ambitious and opinionated men, who had forgotten their duties to their monarch, and their oaths of fidelity. From such men as those, he wished to distinguish the count Leduchowski, for whom he had the highest esteem, and who, he was convinced, had no desire to continue a useless expenditure of blood, and would willingly surrender the fortress to the troops of his legitimate monarch. To all this, marshal Diebitsch added the assurance that the fortress should be garrisoned by equal bodies of Russian and Polish troops. Colonel Leduchowski made a reply to this complimentary communication in nearly the following terms:--'Marshal, to your letter, in which you have chosen to flatter the valor of my countrymen, and in which you have honored me, in particular, with your attentions, I have the honor to answer, that I cannot better deserve your good opinion, than in defending, with my compatriots, our beloved country to the last drop of my blood. This is the course which the honor of each brave Pole dictates to him.']
