“The short principle is,” said Perceval,[72] “that trade in British produce and manufactures, and trade either from a British port or with a British destination, is to be protected as much as possible. For this purpose all the countries where French influence prevails to exclude the British flag shall have no trade but to or from this country, or from its allies. All other countries, the few that remain strictly neutral (with the exception of the colonial trade, which backward and forward direct they may carry on), cannot trade but through this being done as an ally with any of the countries connected with France. If therefore we can accomplish our purpose, it will come to this,--that either those countries will have no trade, or they must be content to accept it through us. This is a formidable and tremendous state of the world; but all the part of it which is particularly harassing to English interests was existing through the new severity with which Bonaparte’s decrees of exclusion against our trade were called into action. Our proceeding does not aggravate our distress from it. If he can keep out our trade he will; and he would do so if he could, independent of our orders. Our orders only add this circumstance: they say to the enemy, ‘If you will not have _our_ trade, as far as we can help it you shall have _none_; and as to so much of any trade as you can carry on yourselves, or others carry on with you through us, if you admit it you shall pay for it. The only trade, cheap and untaxed, which you shall have shall be either direct from us, in our own produce and manufactures, or from our allies, whose increased prosperity will be an advantage to us.’” These private expressions implied that retaliation upon France for her offence against international law was a pretence on the part of Perceval and Canning, under the cover of which they intended to force British commerce upon France contrary to French wishes. The act of Napoleon in excluding British produce from French dominions violated no rule of international law, and warranted no retaliation except an exclusion of French produce from British dominions. The rejoinder, “If you will not have _our_ trade you shall have _none_,” was not good law, if law could be disputed when affirmed by men like Lord Eldon and Lord Stowell, echoed by courts, parliaments, and press,--not only in private, but in public; not only in 1807, but for long years afterward; and not only at moments, but without interruption.
