“ In the confusion the Russian cavalry charged with the utmost fury downhill and with the wind behind them. Three thousand men only out of about fourteen thousand appeared at the evening parade of the corps. The rest were killed, wounded, prisoners or dispersed. The marshal and every senior officer was amongst the killed and wounded, and one regiment, the 14th of the Line, cut off in the midst of the Russians and refusing to surrender, fell almost to a man. The Russian counterstroke penetrated into Eylau itself and Napoleon himself was in serious danger. ”
