Corfe and Portland Castles: Royalist Defenses of 1643
The year 1643 marked a period of intense conflict during the English Civil War, a struggle for power between the Royalists (supporters of King Charles I) and the Parliamentarians (supporters of the English Parliament). Amidst this turmoil, strategic fortifications became the focal points of military endurance and deception.
The Siege of Corfe Castle
One of the most remarkable displays of resilience occurred at Corfe Castle. A stronghold for the Royalist cause, the castle was defended by Mary Bankes. Under her leadership, the fortress withstood a grueling three-year siege imposed by the Parliamentarian forces.
Despite the prolonged pressure and isolation, Bankes' determination kept the stronghold in Royalist hands for years, though the conflict eventually left its mark on the structure.

The Capture of Portland Castle
While Corfe Castle was defined by endurance, the events at Portland Castle were defined by strategy and ruse. In a bold maneuver, a group of Royalists managed to seize control of the castle through deception.
The Royalist forces gained entry to the fortification by pretending to be Parliamentary soldiers, allowing them to infiltrate the defenses and capture the site from within.
