The Dutch Spy Who Saved Amsterdam: Van der Waal's Secret War of 1672
from The Story of the Netherlands: Trade, Empire, and Innovation — Fexingo History · host Fexingo
In 1672, the Dutch Republic faced annihilation. With French troops at the gates of Amsterdam, a shadowy network of spies and informants turned the tide. This episode uncovers the remarkable story of Abraham van der Waal, the Dutch spymaster who infiltrated French supply lines, bribed German mercenaries, and orchestrated the flooding of the Dutch Water Line—a desperate act of hydraulic warfare that saved the Republic. We examine how Van der Waal's intelligence network, funded by the Bank of Amsterdam, manipulated enemy generals and exploited local knowledge of the polders. Drawing on secret correspondence from the Amsterdam City Archives, we reveal the untold human drama behind the 'Year of Disaster': a covert war where a few brave men changed the course of European history through deception, courage, and water. #Rampjaar #1672 #AbrahamVanDerWaal #DutchWaterLine #Spy #Espionage #Amsterdam #FrancoDutchWar #WilliamIII #Polder #HydraulicWarfare #SecretIntelligence #DutchRepublic #YearOfDisaster #Mercenaries #History #FexingoHistory #Netherlands Keep every episode free: buymeacoffee.com/fexingo
