3. The war supposedly took place between Isles of Scilly and Netherlands

4. The war stretched for so long simply because no peace treaty was ever signed.

6. This 335 years’ war originated out of the Second English Civil War that began in 1642 and lasted till 1652. This Second English Civil War was fought between the Parliamentarians and the Royalists.
7. Parliamentarian Oliver Cromwell fought the Royalists to the far edges of England, cornering them in Cornwall, which that the last known Royalists’ stronghold to the west of England.
8. In 1648 however, Cromwell managed to capture mainland Cornwall and the Royalist Navy retreated to the Isles of Scilly (located off Great Britain’s southwest coast). The Isles of Scilly was owned by John Granville who was a Royalist.
9. The United Provinces of Netherlands’ navy was allied to Parliamentarians and since Great Britain helped Netherlands during the Eight Years’ War and aided in Dutch independence from Spain, Netherlands decided to keep alliance with Britain and eventually took sides with the Parliamentarians who were more likely to win the Second Civil War.
10. The Royalist fleet that was stationed in Scilly managed to inflict heavy damage on the Dutch Navy. This forced Admiral Maarten Harpertszoon Tromp of the Dutch Navy to go to Scilly on March 30, 1651 and demand reparations for the damage caused to Dutch Ships. He also asked the Royalists to return the goods they had taken from the Dutch Navy.

12. It was not long after the declaration of war that the Parliamentarian forces commanded by Admiral Robert Blake overpowered the Royalist fleet and forced them to surrender. The surrender took place in June 1651.
13. After the surrender of the Royalist fleet, the Dutch Navy left without firing a single shot because it was no longer under any threat from the Royal fleet.
14. The problem was that Netherlands never officially declared peace because the declaration of war against a small portion of another country was obscure.
15. Over 3 centuries later, Isles of Scilly’s chairman and historian, Mr. Roy Duncan sent a letter to Dutch Embassy in London, asking Netherlands to get rid of the myth that Netherlands and Isles of Sicily was still in a state of war.
