Johann Heinrich von Schmitt (1743 – 1805) was an officer in the Army of the Holy Roman Empire. He was arguably one of the most successful chiefs of staff; he rose to the rank of Feldmarshalleutnant during the French Revolutionary and Napoleonic wars.
In Book 1 Part 2 Chapter 9, Andrei is attached to the Austrian general when Schmitt is killed in a rear-guard battle against the pursuing French army.
