Statues at Large 6th Congress 107 SlaveTradeActP71Sect4

Section 4 of “An Act in addition to the act intituled [sic] ‘An act to prohibit the carrying of the Slave Trade from the United States to any foreign place or country’ ” which describes the rights to prize for American commissioned vessels capturing American slave ships  [1]

On March 22, 1794 the Third Congress passed the first Federal legislation dealing with the slave trade. Applying only to the international, not domestic trade, it prohibited United States citizens and residents from fitting out vessels intended for the foreign slave trade or to buy and sell slaves at foreign ports.  Violators were subject to seizure of their vessels as well as a fine of $2,000 plus an additional $200 per slave [2].

While the costs of violations were steep, the law did little to stem the trade. Owners could choose from a variety of subterfuges to disguise the purpose of voyages. Using sympathetic customs officials, forging ship’s  papers, crewing  vessels with Americans  but sailing under foreign flags, and selling vessels in the West Indies to avoid returning to American ports were all used at one time or another to circumvent the law.

The only enforcement mechanism was for citizens to observe the off loading of slaves at foreign ports — typically in the West Indies — and causing suits to be brought in the Federal Court at the vessel’s home port where, upon return, it could be seized and condemned. Unfortunately, the home ports of these vessels often proved to be unwelcome venues for such suits. Ships condemned and auctioned were often sold back to the original owners at a bargain price when no other bidders materialized, there being a tacit understanding among the locals that they should stay away. To counter this, the Federal Government authorized court clerks to bid on the government’s behalf.  Brazenly, in 1799, owners of the Lucy, of Bristol R.I., arranged for the kidnapping of a customs official on the day of the auction to prevent a competing bid [3]. It would take war with France to provide the U.S. with a different way to enforce the law — at sea.

In 1794, enforcing U.S. law by interdicting the slave trade at sea was not an option. The Unites States had no ocean-going Navy. As we shall see, in 1798 the French finally provided the motivation for the United States to create one for self-defense and, in May 1800, Congress strengthened  the 1794 slave trade law. It increased penalties, closed loopholes and, most important for our story, authorized “any of the commissioned vessels of the United States to seize and take any vessels employed” contrary to the Act. [4]  The legal stage was set for what was to come.
