Salmon P. Chase,
The Peterhoff — Opinion of the Court
“ They assert principles without disregard of which it is impossible to hold that inland trade from Matamoras, in Mexico, to Brownsville or Galveston, in Texas, or from Brownsville or Galveston to Matamoras, was affected by the blockade of the Texan coast.And the general doctrines of international law lead irresistibly to the same conclusion. We know of but two exceptions to the rule of free trade by neutrals with belligerents: the first is that there must be no violation of blockade or siege; and the second, that there must be no conveyance of contraband to either belligerent. ”
