Avowing that a commercial transaction was his object, and that the punishment of France was secondary to a “vindication of our own commerce,” Castlereagh assumed that punishment of France and “vindication” of English commerce were both belligerent rights, as though the right to kill an adversary in a duel implied the right to pick a bystander’s pocket. His colleague and rival Canning was not so confused, for Canning’s duties obliged him to defend the new policy against neutral objections. Carefully as the other ministers mingled the ideas of retaliation and of commerce, the double motive of Perceval’s measure had never been concealed; the intention to permit a licensed trade with France was avowed. Perceval and Castlereagh wanted, not to take commerce from France, but to force commerce upon her; and none of their colleagues could detect this inconsistency so readily as Canning, whose duties would oblige him to assert before the world that retaliation alone was the object of a measure which he privately knew to have no motive but that of commercial rivalry. Canning’s written opinion, beginning by affirming in strong terms the right and justice of retaliation, continued as follows:[68]-- “The question of policy is all that remains; and in this view I should think all such modifications as go to lighten the burden imposed upon neutrals, and as are obviously intended for that purpose, more advisable than any direct reservations for our own interest and advantage. For this reason I would rather confine the measure to a part of the countries in the occupation of the enemy (a large part to be sure,--France and Holland, for instance), and apply it in all its rigor to that part, than extend it to the whole and relax it generally by complicated exceptions and regulations. And I would keep out of sight the exceptions in favor of ships going from this country, the benefit of which might be equally obtained by licenses; but the _publication_ of that exception would give to the measure the air of a commercial rather than a political transaction.”
