Overview
Case summary
The Peterhoff, a British merchant steamer, was captured in 1863 during the American Civil War while documented for a voyage from London to Matamoras, Mexico. The United States alleged the vessel intended to violate the blockade of Southern States and carried contraband. The Supreme Court held that the mouth of the Rio Grande was not included in the blockade, as it was half in Mexican territory with treaty-guaranteed navigation rights. Trade with Matamoras, even with intent to supply Texas by inland conveyance, was lawful. However, portions of the cargo (artillery harness, army boots, etc.) were contraband destined for rebel forces and subject to condemnation, along with other cargo owned by the same owner. The captain's conduct in refusing papers and destroying a package warranted costs against the ship but not condemnation. The Court reversed the District Court's condemnation of vessel and most cargo, but affirmed condemnation of contraband portions.
Abstract
A neutral merchant vessel was captured on suspicion of violating a wartime blockade and carrying contraband destined for rebel forces, despite being documented for a lawful voyage to a neutral Mexican port with guaranteed navigation rights. The court held that trade to the port was permissible even if goods might be transshipped inland, but condemned specific contraband cargo items like artillery harness and army boots while restoring the vessel and non-contraband cargo. The captain's obstructive conduct warranted costs against the ship, leading to reversal of the lower court's full condemnation and remand for partial enforcement.
