Nansouty, who had opened the battle, was now sent in by Napoleon to deliver the _coup-de-grace_.

With characteristic gallantry he fell upon the Russian columns.
Sacken was driven from the field.

In killed, wounded, and prisoners he had lost half his force and all of his guns.

His troops streamed westward through roads and woods in wild confusion.

He would have been annihilated then and there but for the arrival of Yorck.
