Longest war in history

[Dutchman]

I read about this in a special section of our newspaper and thought if I'd be able to look it up on the internet so the info would be in English.
But we have been at war with the Scilly Islands for 335 years, read below what happened:

On 17 April 1986 a remarkable event occurred in the Isles of Scilly - something overlooked by history books and the Guinness Book Of World Records - the longest war in history was ended.

It all started during the English Civil War (1642-1648), when Parliamentarianism was spreading through the country on the back of Oliver Cromwell (1599-1658). Royalist strongholds, areas where the Royal armies were still in control, were being beaten back - further and further away from London.

Scilly was soon the last place to be a Royalist stronghold, owned by Royalist supporter Sir John Grenville. Mainland England had been cleared of such supporters by the Parliamentarians.

The Parliamentarians' supporters, the Netherlands, sent ships in to aid the struggle against the Royalists. As Scilly became the last Royalist stronghold, the Royalist navy operated from the Islands.

So much havoc was caused by the Royalist navy on the Dutch navy that the Dutch decided to declare war. However, they could not declare war on England, as it was not England at fault - it was the Royalists, and the Royalists were in Scilly - so they declared war on the Islands.

Admiral Maarten Harpertszoon Tromp (1597-1653) went to Scilly to demand reparation for the Dutch ships and goods taken by them and, after receiving no satisfactory answer, declared war.

War was declared in 1651. Immediately after war was declared, Admiral Robert Blake (1599-1657) arrived in Scilly with the Parliamentarian fleet and said that he would deal with the pirates. In June 1651, Scilly's Royalist stronghold fell to the Parliamentarians. The war was over and forgotten about, even before the Dutch managed to fire a single shot. However, the Dutch also forgot to sign a peace treaty with the Islands.

In 1985, local historian-come-Chairman of the Council, Roy Duncan, decided to look into the rumours that "Scilly was still at war with the Netherlands". When he asked the Dutch embassy in London, they said that the rumour was accurate. Cllr. Duncan decided to invite the Dutch ambassador in London, Jonkheer Huydecoper, to the Islands in order to sign they treaty.

The treaty was signed on 17 April 1986, 335 years after it was declared.
