 Napoleon supported this ruse by issuing orders to his aide-de-camp Berthier about grenadier and artillery units that Berthier knew were entirely bogus.Oberst Knorr surrendered one battalion each of "De Vins" IR # 37 and "Erbach" IR # 42, a total of 2,000 men and 3 cannons.The Austrians only discovered once they had surrendered and been disarmed that there were no French forces nearby, and that they could have captured Napoleon with ease.
