It was manifest that the course of action adopted by Europe, while based on an apparent refusal to determine the question or to side with either party, was, in point of fact, an actual decision against our rights and in favor of the groundless pretensions of the United States. It was a refusal to treat us as an independent government. If we were independent States, the refusal to entertain with us the same international intercourse which was maintained with our enemy was unjust, and was injurious in its effects, whatever might have been the motive which prompted it. Neither was it in accordance with the high moral obligations of that international code, whose chief sanction is the conscience of sovereigns and the public opinion of mankind, that those eminent powers should have declined the performance of a duty peculiarly incumbent on them, from any apprehension of the consequences to themselves. One immediate and necessary result of their declining the responsibility of a decision, which must have been adverse to the extravagant pretensions of the United States, was the prolongation of hostilities to which our enemies were thereby encouraged, and which resulted in scenes of carnage and devastation on this continent and of misery and suffering on the other such as have scarcely a parallel in history. Had those powers promptly admitted our right to be treated as all other independent nations, none can doubt that the moral effect of such action would have been to dispel the pretension under which the United States persisted in their efforts to accomplish our subjugation.
There were other matters in which less than justice was rendered to the Confederacy by "neutral" Europe, and undue advantage conferred on the aggressors in a wicked war. At the inception of hostilities, the inhabitants of the Confederate States were almost exclusively agriculturists; those of the United States were also to a large extent mechanics, merchants, and navigators. We had no commercial marine, while their merchant-vessels covered the ocean. We were without a navy, while they had powerful fleets built by the money we had in full share contributed. The power which they possessed for inflicting injury on our coasts and harbors was thus counterbalanced in some measure by the exposure of their commerce to attack by private armed vessels. It was known to Europe that within a very few years past the United States had peremptorily refused to accede to proposals for the abolition of privateering, on the ground, as alleged by them, that nations owning powerful fleets would thereby obtain undue advantage over those possessing inferior naval force. Yet no sooner was war flagrant between the Confederacy and the United States than the maritime powers of Europe issued orders prohibiting either party from bringing prizes into their ports. This prohibition, directed with apparent impartiality against both belligerents, was in reality effective against, the Confederate States only, for they alone could find a hostile commerce on the ocean. Merely nominal against the United States, the prohibition operated with intense severity on the Confederacy by depriving it of the only means of maintaining its struggle on the ocean against the crashing superiority of naval force possessed by its enemies. The value and efficiency of the weapon which was thus wrested from our grasp by the combined action of "neutral" European powers, in favor of a power which professes openly its intention of ravaging their commerce by privateers in any future war, is strikingly illustrated by the terror inspired among commercial classes of the United States by a single cruiser of the Confederacy. One small steamer, commanded by officers and manned by a crew who were debarred by the closure of neutral ports from the opportunity of causing captured vessels to be condemned in their favor as prizes, sufficed to double the rates of marine insurance in Northern ports, and consign to forced inaction numbers of Northern vessels, in addition to the direct damage inflicted by captures at sea.
But it was especially in relation to the so-called blockade that the policy of European powers was so shaped as to cause the greatest injury to the Confederacy, and to confer signal advantages on the United States. A few words in explanation may here be necessary.
Prior to the year 1856 the principles regulating this subject were to be gathered from the writings of eminent publicists, the decisions of admiralty courts, international treaties, and the usages of nations. The uncertainty and doubt which prevailed in reference to the true rules of maritime law, in time of war, resulting from the discordant and often conflicting principles announced from such varied and independent sources, had become a grievous evil to mankind. Whether a blockade was allowable against a port not invested by land as well as by sea, whether a blockade was valid by sea if the investing fleet was merely sufficient to render ingress to the blockaded port evidently dangerous, or whether it was further required for its legality that it should be sufficient "really to prevent access," and numerous other similar questions, had remained doubtful and undecided.
Animated by the highly honorable desire to put an end "to differences of opinion between neutrals and belligerents, which may occasion serious difficulties and even conflicts" (such was the official language), the five great powers of Europe, together with Sardinia and Turkey, adopted in 1856 the following declaration of principles:
"1. Privateering is and remains abolished.
"2. The neutral flag covers enemy's goods, with the exception of contraband of war.
"3. Neutral goods, with the exception of contraband of war, are not liable to capture under enemy's flag.
"4. Blockades, in order to be binding must be effective, that is to say, maintained by a force sufficient really to prevent access to the coast of the enemy."
Not only did this solemn declaration announce to the world the principles to which the signing powers agreed to conform in future wars, but it contained a clause to which these powers gave immediate effect, and which provided that the states, not parties to the Congress of Paris, should be invited to accede to the declaration. Under this invitation every independent state in Europe yielded its assent—at least, no instance is known to me of a refusal; and the United States, while declining to assent to the proposition which prohibited privateering, declared that the three remaining principles were in entire accordance with their own views of international law.
