Who was Hans de Witte, and how did he help Albrecht von Wallenstein build an army?

Hans de Witte was a financial agent who played a critical role in the military operations of Albrecht von Wallenstein. During the Danish War (1625–1629), when Wallenstein proposed raising an independent imperial army of 24,000 men without burdening the imperial treasury, de Witte was tasked with providing the necessary capital.1

Specifically, de Witte advanced the ready cash required for the equipment and pay of the soldiers. This financial arrangement allowed Wallenstein to enlist regiments by advancing money to his colonels, a strategy that effectively bound those officers to his personal command. The agreement stipulated that de Witte would be reimbursed for these expenditures through taxes and tributes collected from the districts conquered by the army.1
