The Commander of the Austrian army in the Southern Netherlands, Leao, looked even more distressed.
Accompanying the reinforcements that arrived in Luxembourg was a secret letter from Joseph II. The letter instructed him to drag the French Army into battle against the Prussians and the Hanoverians if possible, and if necessary, lead the enemy forces into the Luxembourg area.
However, Leao knew better than anyone how cunning the French people were, through his interactions with the French Army during this period.
They constantly provoked him to engage in a decisive battle with Blucher, while setting up their camp at the rear of the Austrian troops and beginning to construct breastworks along the borders of Luxembourg and Liege—a form of simple defensive fortification, as if they were preparing to defend Luxembourg to the death.
