The king had withdrawn with the remainder of his troops, which were commanded by the gallant L'Estoc, to Koenigsberg, where he formed a junction with the Russian army, which was led by a Hanoverian, the cautious Bennigsen, and accompanied by the emperor Alexander in person. Napoleon expected that an opportunity would be afforded for the repetition of his old manoeuvre of separating and falling singly upon his opponents, but Bennigsen kept his forces together and offered him battle at Eylau, in the neighborhood of Koenigsberg; victory still wavered, when the Prussian troops under L'Estoc fell furiously upon Marshal Ney's flank, while that general was endeavoring to surround the Russians, and decided the day. It was the 8th of February, and the snow-clad ground was stained with gore. Napoleon, after this catastrophe, remained inactive, awaiting the opening of spring and the arrival of reinforcements. Dantzig, exposed by the desertion of the Poles, fell, although defended by Kalkreuth, into his hands, and, on the 14th of June, 1807, the anniversary, so pregnant with important events, of the battle of Marengo, he gained a brilliant victory at Friedland, which was followed by General Ruchel's abandonment of Koenigsberg with all its stores. The road to Lithuania now lay open to the French, and the emperor Alexander deemed it advisable to conclude peace. A conference was held at Tilsit on the Riemen between the sovereigns of France, Russia, and Prussia, and a peace, highly detrimental to Germany, was concluded on the 9th of July, 1807. Prussia lost half of her territory, was restricted to the maintenance of an army merely amounting to forty-two thousand men, was compelled to pay a contribution of one hundred and forty millions of francs to France, and to leave her most important fortresses as security for payment in the hands of the French. These grievous terms were merely acceded to by Napoleon "out of esteem for his Majesty the emperor of Russia," who, on his part, deprived his late ally of a piece of Prussian-Poland (Bialystock) and divided the spoil of Prussia with Napoleon.[10] Nay, he went, some months later, so far in his generosity, as, on an understanding with Napoleon and without deigning any explanation to Prussia, arbitrarily to cancel an article of the peace of Tilsit, by which Prussia was indemnified for the loss of Hanover with a territory containing four hundred thousand souls.
