Wellington only determined Napoleon’s intentions with certainty in the evening, and his orders for his army to muster near Nivelles and Quatre Bras were sent out just before midnight.
Wellington tegi Napoleoni kavatsused kindlaks alles õhtul ja tema käsud armeele Nivelles'i ja Quatre Bras'i lähistele koondumiseks saadeti välja vahetult enne keskööd.
