But no sooner had he taken this irretrievable step than the mask was dropped. The French skirmishers advanced in force; heavy columns of infantry began to show themselves; batteries of cannon were got into position; and all circumstances concurred, with the report of prisoners, to assure Bennigsen, that he, with his enfeebled forces, was in presence of the grand French army. His position, a sort of plain, surrounded by woods and broken ground, was difficult to defend; with the town and a large river in his rear, it was dangerous to attempt a retreat, and to advance was prevented by the inequality of his force. Bennigsen now became anxious to maintain his communication with Wehlau, a town on the Pregel, which was the original point of retreat, and where he hoped to join with the Prussians under General L'Estocq. If the enemy should seize the bridge at Allerberg, some miles lower down the Aller than Friedland, this plan would become impossible, and he found himself therefore obliged to diminish his forces, by detaching six thousand men to defend that point. With the remainder of his force he resolved to maintain his present position till night. The French advanced to the attack about ten o'clock. The broken and wooded country which they occupied, enabled them to maintain and renew their efforts at pleasure, while the Russians, in their exposed situation, could not make the slightest movement without being observed. Yet they fought with such obstinate valour, that at noon the French seemed sickening of the contest, and about to retire. But this was only a feint, to repose such of their forces as had been engaged, and to bring up reinforcements. The cannonade continued till about half past four, when Buonaparte brought up his full force in person, for the purpose of one of those desperate and generally irresistible efforts to which he was wont to trust the decision of a doubtful day. Columns of enormous power, and extensive depth, appeared partially visible among the interstices of the wooded country, and, seen from the town of Friedland, the hapless Russian army looked as if surrounded by a deep semicircle of glittering steel. The attack upon all the line, with cavalry, infantry, and artillery, was general and simultaneous, the French advancing with shouts of assured victory; while the Russians, weakened by the loss of at least twelve thousand killed and wounded, were obliged to attempt that most dispiriting and dangerous of movements--a retreat through encumbered defiles, in front of a superior enemy. The principal attack was on the left wing, where the Russian position was at length forced. The troops which composed it streamed into the town, and crowded the bridge and pontoons; the enemy thundered on their rear, and without the valour of Alexander's Imperial Guard, the Russians would have been utterly destroyed. These brave soldiers charged with the bayonet the corps of Ney, who led the French vanguard,
