The shortest and longest war in history?

[Brutus]

Another very short war: The "Kettle War" was 'fought' between the Dutch Republic and the Holy Roman Empire on 8 October 1784. Emperor Joseph II sent 3 ships up the Scheldt to break the Dutch blockade of the river (which had been in effect since the 16th Century). The Dutch ship De Dolfijn shot one cannonball, which hit the cooking kettle aboard the Imperial warship Le Louis. The Imperials immediately surrendered and a year later a peace was signed.
