A better knowledge of American geography would have made clear to Russell that if but seven Southern ports were effectively blockaded the remaining 2,550 miles of coast line would be useless for the export of cotton in any considerable amount. His bays and creeks did indeed long provide access to small vessels, but these were not adequate for the transport of a bulky export like cotton[531]. To Russell, however, the blockade appearing negligible in probable effect and also not open to objection by neutrals if regularly established, it seemed that any immediate danger to British trade was averted by the final American action on the "Southern Ports" Bill. It was not until the blockade did begin to be thoroughly effective that either the British public or Government gave it serious consideration.

Not again until late November did Russell return with any interest to the subject of the blockade and then it was again on an American effort which seemed to indicate the ineffectiveness of blockading squadrons and a plan to remedy this by unusual, even "uncivilized," if not illegal, methods. This was the "Stone Boat Fleet" plan of blocking Charleston harbour by sinking vessels across the entrance bar[532]. The plan was reported by Lyons and the news received in England at the most uncertain moment as to the outcome of the Trent controversy[533]. British press and Government at first placed no stress on it, presumably because of the feeling that in view of the existing crisis it was a minor matter. In the same week Lyons, having been asked by Russell for an opinion on the blockade, answered:

"I am a good deal puzzled as to how I ought to answer your question whether I consider the Blockade effective. It is certainly by no means strict or vigorous along the immense extent of coast to which it is supposed to apply. I suppose the ships which run it successfully both in and out are more numerous than those which are intercepted. On the other hand it is very far from being a mere Paper Blockade. A great many vessels are captured; it is a most serious interruption to Trade; and if it were as ineffective as Mr. Jefferson Davis says in his Message, he would not be so very anxious to get rid of it[534]."

This was a very fair description of the blockade situation. Lyons, unaffected by irritations resulting from the Trent, showed the frame of mind of a "determined neutral," as he was fond of describing himself. His answer was the first given to Russell indicating a possibility that the blockade might, after all, become strictly effective and thus exceedingly harmful to British trade. There is no direct proof that this influenced Russell to denounce the plan of blocking Southern harbours with stone-laden boats sunk in the channel, but the existence of such a motive seems probable. Moreover his protest was not made until December 20, the day after he had learned officially from Adams that Wilkes was unauthorized in searching the Trent--a day on which strain and uncertainty regarding American intentions were greatly lessened. Russell then wrote to Lyons that he observed it to be stated, "apparently on good authority," that the declared purpose of the stone boat fleet was "of destroying these harbours for ever." He characterized this as implying "utter despair of the restoration of the Union," and as being only "a measure of revenge and irremediable injury against an enemy."

"But even in this view, as a scheme of embittered and sanguinary war, such a measure is not justifiable. It is a plot against the commerce of nations and the free intercourse of the Southern States of America with the civilized world. It is a project worthy only of times of barbarism."

Lyons was instructed to speak in this sense to Seward, who, it was hoped, would disavow the project[535].

There was nothing in Lyons' despatches, nor in the American newspaper extracts accompanying them, to warrant such accusation and expostulation. Lyons had merely commented that by some in America the project had been characterized as "odious and barbarous," adding, "The question seems to depend on the extent to which the harbours will be permanently injured[536]." It will be noted that Russell did not refer to information received from Lyons (though it was already in hand), but to "apparently good authority" in justification of his vigorous denunciation. But like vigour, and like characterization of American "barbarism" did not appear in the British press until after the news arrived of the release of Mason and Slidell. Then the storm broke, well summed up in the Punch cartoon entitled "Retrogression. (A Very Sad Picture.) War Dance of the I.O.U. Indian," and showing Uncle Sam in war-feathers and with war-club, in his hand a flag made of the New York Herald, dancing in glee on the shores of a deserted harbour across which stretched a row of sunken ships[537].

On January 13 the Liverpool Shipowners' Association called the attention of the Foreign Office to the news that Charleston harbour had been closed by stone boats and urged governmental remonstrance[538]. Hammond at once replied quoting the language of Russell's letter of December 20 and stating that further representations would be made[539]. On the sixteenth Russell again instructed Lyons to speak to Seward, but now was much less rasping in language, arguing, rather, the injury in the future to the United States itself in case the harbours were permanently destroyed since "... the object of war is peace, and the purposes of peace are mutual goodwill and advantageous commercial intercourse[540]." To-day it seems absurd that any save the most ignorant observer should have thought the North contemplated a permanent and revengeful destruction of Southern port facilities. Nor was there any just ground for such an extreme British view of the Northern plan. Yet even Robert Browning was affected by the popular outcry. "For what will you do," he wrote Story, "if Charleston becomes loyal again[541]?" a query expressive of the increasing English concern, even alarm, at the intense bitterness, indicating a long war, of the American belligerents. How absurd, not to say ridiculous, was this British concern at an American "lapse toward barbarism" was soon made evident. On January II Lyons, acting on the instructions of December 20, brought up the matter with Seward and was promptly assured that there was no plan whatever "to injure the harbours permanently." Seward stated that there had never been any plan, even, to sink boats in the main entrance channels, but merely the lesser channels, because the Secretary of the Navy had reported that with the blockading fleet he could "stop up the 'large holes,'" but "could not stop up the 'small ones.'" Seward assured Lyons that just as soon as the Union was restored all obstructions would be removed, and he added that the best proof that the entrance to Charleston harbour had not been destroyed was the fact that in spite of blockading vessels and stone boats "a British steamer laden with contraband of war had just succeeded in getting in[542]." Again, on February 10, this time following Russell's instruction of January 16, Lyons approached Seward and was told that he might inform Russell that "all the vessels laden with stone, which had been prepared for obstructing the harbours, had been already sunk, and that it is not likely that any others will be used for that purpose[543]." This was no yielding to Great Britain, nor even an answer to Russell's accusation of barbarity. The fact was that the plan of obstruction of harbours, extending even to placing a complete barrier, had been undertaken by the Navy with little expectation of success, and, on the first appearance of new channels made by the wash of waters, was soon abandoned[544].

The British outcry, Russell's assumption in protest that America was conducting war with barbarity, and the protest itself, may seem at first glance to have been merely manifestations of a British tendency to meddle, as a "superior nation" in the affairs of other states and to give unasked-for advice. A hectoring of peoples whose civilization was presumably less advanced than that which stamped the Englishman was, according to Matthew Arnold, traditional--was a characteristic of British public and Government alike[545]. But this is scarcely a satisfactory explanation in the present case. For in the first place it is to be remarked that the sinking of obstructions in an enemy's harbours in order to render more effective a blockade was no novelty in maritime warfare, as Russell must have well known, and that there was no modern record of such obstructions having permanently destroyed a harbour. A far more reasonable explanation is that which connects the energy of the British Government in opposing a proposed American closing of Southern harbours by Presidential proclamation, with a like energy against the stone boat project. The first method was indeed rightly regarded as a violation of accustomed maritime belligerency, but both methods were primarily objectionable in British eyes because they were very evidently the result of efforts to find a way in which an as yet ineffective blockade could be made more rigorous. On the impossibility of an effective blockade, if conducted on customary lines, the British people and Foreign Secretary had pinned their faith that there would be no serious interruption of trade. This was still the view in January, 1862, though doubts were arising, and the "stone boat" protest must be regarded as another evidence of watchful guardianship of commerce with the South. The very thought that the blockade might become effective, in which case all precedent would demand respect for it, possibly caused Russell to use a tone not customary with him in upbraiding the North for a planned "barbarity."
