In fact the proposed treatment of privateers as pirates might have resulted in very serious complications, for though the Proclamation of Neutrality had warned British subjects that they would forfeit any claim to protection if they engaged in the conflict, it is obvious that the hanging as a pirate of a British seaman would have aroused a national outcry almost certain to have forced the Government into protest and action against America.

Fortunately the cooler judgment of the United States soon led to quiet abandonment of the plan of treating privateers as pirates, while on the other point of giving "shelter" to Confederate privateers Seward himself received from Lyons assurance, even before Adams had made a protest, that no such shelter would be available in British ports[183].
In this same letter of May 21 Seward, writing of the rumour that the Southern envoys were to be received by Russell "unofficially," instructed Adams that he must use efforts to stop this and that: "You will, in any event, desist from all intercourse whatever, unofficial as well as official, with the British Government, so long as it shall continue intercourse of either kind with the domestic enemies of this country." Here was a positive instruction as to the American Minister's conduct in a given situation, and a very serious instruction, nearly equivalent to "taking leave" after a rupture of diplomatic relations, but the method to be used in avoiding if possible the necessity of the serious step was left to Adams' discretion.

Well might Adams' comment, when reporting the outcome, that this was the "most delicate portion of my task[184]." Adams again went over with Russell the suspicion as to British intentions aroused in America by the Queen's Proclamation, but added that he had not been able to convince himself of the existence of an unfriendly design.

"But it was not to be disguised that the fact of the continued stay of the pseudo-commissioners in this city, and still more the knowledge that they had been admitted to more or less interviews with his lordship, was calculated to excite uneasiness.
Indeed, it had already given great dissatisfaction to my Government.

I added, as moderately as I could, that in all frankness any further protraction of this relation could scarcely fail to be viewed by us as hostile in spirit, and to require some corresponding action accordingly." Russell replied that both France and England had long been accustomed to receive such persons unofficially, as in the case of "Poles, Hungarians, Italians, etc.," to hear what they had to say.
