May – September 14, 1629
's-Hertogenbosch sat in a marsh and was thought impregnable — no one had ever taken it. Frederick Henry drained the marsh. He dammed the rivers, built forty kilometres of siege works around the town and a second ring facing outward against relief, and pumped the swamp dry with windmills, then mined the walls. It fell in four months.
