Having lost full 12,000 men, General Bennigsen was at last compelled to attempt a retreat; the French poured after him into the town: the first Russian division which forced the passage of the river destroyed the bridge behind them in their terror; and the rest of the army escaped by means of deep and dangerous fords, which, desperate as the resource they afforded was, had been discovered only in the moment of necessity.
Nevertheless such were the coolness and determination of the Russians, that they saved all their baggage, and lost only seventeen cannon; and such was the impression which their obstinate valour left on the enemy, that their retreat towards the Niemen was performed without any show of molestation.
The results of the battle of Friedland were, however, as great as could have been expected from any victory.

On the retreat of Bennigsen towards the Niemen, the unfortunate King of Prussia, evacuating Konigsberg, where he now perceived it must be impossible to maintain himself, sought a last and precarious shelter in the seaport of Memel; and the Emperor Alexander, overawed by the genius of Napoleon, which had triumphed over troops more resolute than had ever before opposed him, and alarmed for the consequence of some decisive measure towards the re-organisation of the Poles as a nation, began to think seriously of peace.

Buonaparte, on his part also, had many reasons for being anxious to bring hostilities to a close.

The Swedish king was in Pomerania, besieging Stralsund, and hourly expecting reinforcements from England, which might have ended in a formidable diversion in the rear of the French army.

Schill, an able partizan, was in arms in Prussia, where the general discontent was such, that nothing by opportunity seemed wanting for a national insurrection against the conquerors.
