The Siege of Curaçao was a battle in Curaçao in 1800 during the Quasi-War between the French Navy and the Batavian Republic, the United States Navy and the Royal Navy. The French had landed on the island on 22 July, and on 5 September attacked and captured a fort protecting the town of Willemstad. The American consul sent for help, and on 10 September the governor of the island surrendered to a British frigate HMS Nereide who promised to protect the town but did little to help. On 22 September the sloops USS Patapsco and USS Merrimack arrived, on 23 September the Patapsco sailed into the harbor and landed marines to reinforce the garrison protecting the town. On 23 September and 24 September the French fired upon the defenders; however, instead of assaulting the town, the French forces left the island during the night, the British took control of the island, and the American forces sailed away.


The island of Curaçao was important to American merchants in the Caribbean, and ships had been stationed near there to guard American interests since the start of the Quasi-War. The sloop USS Patapsco was ordered to sail there in May 1800, and arrived in June and left soon afterwards. No American ships were stationed at Curaçao on 23 July when a French fleet arrived from Guadeloupe, consisting of 5 ships and 1400 men and sailors. The French forces landed and their commander demanded the surrender of the forts, which Governor Johan Lausser refused.[1][2]


An additional 10 vessels with more sailors and men had landed by 5 September, when the French forces attacked the forts protecting the town of Willemstad, capturing one and sending a note threatening to attack Americans. American consul Benjamin Phillips sent a messenger to St. Kitts, and the USS Merrimack and Patapsco were sent to Curaçao on 14 September, arriving on 22 September.[3]

Meanwhile, the British frigate HMS Nereide under Frederick Watkins had been sent to the island to prevent its capture by the French. On 10 September the ship arrived at the eastern point of Curaçao, and there chased two privateers that the French commander had left cruising as pickets. After these vessels retreated into a bay that contained a further 15 privateers, Watkins sailed to Willemstad where he began engaging various targets that were firing in the town.[4] An American merchantman soon informed the British of the situation and that the Dutch were willing to capitulate to the British in exchange for protection. The British landed a force of twenty marines and accepted Governor Lassuer's surrender three days later.[5] The French still held two forts near the town, and on 22 September, prior to the arrival of the American forces, the French commander had demanded the surrender of the town within 24 hours.[3]


On 23 September, to save the town and protect American property, the Patapsco sailed into the harbor, landed her marines, reinforced with twenty marines from the Merrimack. The marines manned a gun battery and fanned out through the town. At approximately 17:00 the French forts and men fired upon the defending forces, which the cannon of the Patapsco answered along with the muskets and cannon of the defending forces. Two Americans were wounded with an unknown number of French casualties.[6]

On 24 September, the French again exchanged cannon and musket fire with the defending forces, and the volume of French fire led the defenders to expect an assault on the town. However, during the night the French abandoned their positions and sailed away.[6]


On the morning of 25 September, the Merrimack discovered the French ships had sailed away during the night. The Nereid sailed into the town and the capitulation took effect.[7] Fearing that the French would return, Watkins asked the two American captains to cruise off the windward side of the island while Nereid secured the island. In ten days of cruising, the Americans captured only one French vessel before stopping off at Willemstad while on their return to Saint Kitts.[7][8] Upon their return to Curaçao, the Americans discovered that Watkins had failed to keep his word, and instead of protecting American property, had embargoed forty-one ships in the harbor of which seven were American. The Nereid's commander also impounded a large quantity of specie belonging to Consul Phillips and set British privateers cruising with orders to seize American shipping. In his reports, Watkins completely ignored the assistance the Americans had provided in seizing the island and failed to even mention their presence during the action. Watkins's treatment of the Americans was not approved by British officials and upon the appointment of a new commander for the British Jamaica Station he was stripped of his command and the specie he had seized was returned.[8][9]
