Quasi-War

1798–1800

An undeclared war at sea between the United States and France. Angry that the Americans had made a treaty with Britain, the French Republic let its privateers prey on American merchant ships, taking hundreds of them in the West Indies, and when American envoys sent to Paris were asked for bribes in the XYZ Affair, Congress built a navy. Its new frigates and converted merchantmen convoyed trade and hunted privateers in the Caribbean, working from British islands. Thomas Truxtun's Constellation beat two French frigates, and smaller ships took dozens of privateers; in May 1800 Isaac Hull led a party from Constitution that cut out a French privateer from under the guns of a Spanish fort at Puerto Plata. The Convention of 1800 ended the fighting in September.
