The War Ended by a Single Shot to a Soup Kettle
In October 1784, the Holy Roman Empire and the Republic of the Seven United Netherlands came to the brink of war over trade rights on the Scheldt River. The conflict, known as the Kettle War, ended almost as soon as it began. An imperial flagship fired a single shot at a Dutch merchant ship, which hit a soup kettle on deck. Terrified by this display of force, the imperial crew surrendered immediately, ending the war.
The Bottleneck on the Scheldt
The conflict that culminated in the Kettle War had its roots more than a century earlier in the Peace of Westphalia of 1648. That landmark treaty brought an end to the Eighty Years' War and formally established the independence of the Dutch Republic from the Spanish Empire. As part of the settlement, the northern Dutch secured control over the mouth of the Scheldt River, the vital maritime artery connecting the inland port of Antwerp to the North Sea.
By closing the Scheldt to deep-sea navigation, the Dutch Republic effectively crippled Antwerp as a commercial rival to Amsterdam and Rotterdam. For over a century, goods destined for Antwerp had to be transferred to Dutch vessels at the border and subjected to heavy tolls. This arrangement enriched Dutch merchants while stifling economic development in the Southern Netherlands, which eventually passed from Spanish to Austrian Habsburg rule.
An Emperor's Ultimatum
By the late 18th century, Holy Roman Emperor Joseph II sought to modernize and revitalize his disparate domains, including the Austrian Netherlands. Viewing the closure of the Scheldt as an outdated, unjust barrier to commerce, Joseph II demanded that the Dutch Republic grant free navigation along the river. When diplomatic overtures yielded no concessions, the emperor decided to force the issue through direct action.
In October 1784, Joseph II ordered imperial vessels to test the Dutch blockade. The imperial brig Le Louis set sail from Antwerp toward the North Sea, flying the imperial flag, with orders not to yield to Dutch authority. At the same time, another imperial ship was instructed to sail in the opposite direction from the sea up the river toward Antwerp, presenting the Dutch with a coordinated challenge to their territorial monopoly.
