Frederick Henry and Ernst Casimir of Nassau-Dietz at the Siege of ’s Hertogenbosch, c....

Prince Frederick Henry and his cousin Count Ernst Casimir pose triumphantly on their horses before ’s-Hertogenbosch. Frederick Henry points his commander’s staff at the Habsburg-occupied city now being stormed by Dutch forces. It was not for nothing that he was nicknamed ‘the conqueror of cities’. He captured a series of cites from the Spanish. The retaking of ‘s-Hertogenbosch in 1629 was one of the most important in the Thirty Years War, part of the Eighty Years' War, an armed revolt under the leadership of Protestant William of Orange when the Dutch struggled to gain independence from Spanish rule under the Catholic Philip II.
