4. The Blockade of La Rochelle (1627-1628)
Cardinal Richelieu’s blockade of La Rochelle isolated the Huguenot stronghold by constructing a 1,400-meter seawall, effectively cutting off the city’s maritime resupply routes. This strategy led to the city’s surrender after months of resistance, underscoring the rising power of central governments to employ naval tactics domestically to quell internal rebellion (britannica.com).
