Though unscientific as a military move and futile as to the ultimate result of the war, the capture of Rheims was, nevertheless, a telling thrust. On receipt of the news from Laon, Schwarzenberg had immediately set his army in motion against Macdonald, and Bluecher, after waiting two days to restore order among his worried troops and insubordinate lieutenants, had advanced and laid siege to Compiegne.

The French halted at Nangis in their retreat before Schwarzenberg, and the people of Compiegne were released from the terrors of a siege.

He had beaten us all, one after the other; we were always frightened by the daring of his enterprises, the swiftness of his movements, and his clever combinations.
