One of the earliest tests of the
Clayton–Bulwer Treaty, the
Prometheus Incident arose from Cornelius Vanderbilt's refusal to pay customs duty in what was then Greytown – now
San Juan de Nicaragua. Upon receiving a fifth such refusal, on November 21, 1851, the British resident, James Green, asked Commander Fead to provide physical assistance. Fead promptly maneuvered his ship into position and fired a live round across the bow of the
Prometheus – an American vessel owned by the canal company – while Vanderbilt was on board. After being forced to pay the customs duty, an enraged Vanderbilt returned to the US and inflamed anti-British sentiment in the press. Fead's actions were found to be in violation of Article 1 of the Clayton–Bulwer Treaty. == References ==
