CUSHING AIDS NAVIGATION OF TRENT AFFAIR Jim Dyer 5/10/11 Just before Christmas 1861, Newburyport’s Caleb Cushing sat in the library of his High Street home and reviewed once again the 30+ page memorandum he had just completed for Secretary of State William H. Seward. In the morning he must precede post haste to Washington, DC to meet with the Secretary of State about the “Trent Affair” which had Great Britain mobilizing for war. On November 8, 1861 the British mail packet RMS Trent had been intercepted by the steam sloop of war USS San Jacinto, commanded by Captain Charles Wilkes. Two Confederate diplomats, former US Senators James Mason This portrait depicts Caleb Cushing, and John Slidell had been removed before the (1800-1879). Trent was sent on its way. The envoys were Massachusetts Historical Society 154 Boylston Street (directions) bound for Great Britain and France in order to Boston, MA 02215-3695 press the Confederacy’s case for diplomatic Tel: 617.536.1608 recognition by Europe. They were summarily transported to Boston and imprisoned in Fort Warren. The reaction in Newburyport and throughout the North was wildly enthusiastic, especially with no other Union victories to celebrate. The Trent arrived in London November 27th and reported the boarding. The British public expressed outrage at this perceived insult to their national honor. The British government demanded an apology and the release of the prisoners while it also took steps to strengthen its military forces in Canada and in the Atlantic. Because the first Atlantic telegraph cable between Great Britain and the United States had been accidentally severed in late 1858, news across the Atlantic traveled by boat and was often delayed by as much as twelve or fourteen days. By the time U. S. Secretary of State William Seward received the note of protest from Lord Palmerston, France had declared its support for Britain in the matter, even if it meant war with the United States. In Canada, nationalistic leader John MacDonald mobilized militia across the southern frontier. Were Seward and Lincoln willing to go to war over the matter? In the Confederate States the hope was that the incident would lead to a permanent rupture in Union-British relations, diplomatic recognition, and Southern independence. The leadership of the Confederacy had long believed that European dependence on cotton for its textile industry would lead to diplomatic recognition and intervention in the form of mediation. The United States had already made it clear any movement by Britain towards official recognition of the Confederacy would be considered a hostile act. William H. Seward (c. 1850) The US was still on edge about British intentions. Great Britain had declared themselves ‘neutral’ in May of 1861. That served as de facto recognition of Southern belligerency - a status that provided Confederate ships the same privileges in foreign ports that Union ships received. Confederate ships could obtain fuel, supplies and repairs in neutral ports but could not secure military equipment or arms. The availability of Britain’s far-flung colonial ports made it possible for Confederate ships to pursue Union shipping throughout much of the world. To make matters worse France, Spain, the Netherlands and Brazil had declared neutrality, too. This international recognition of their “belligerent” status gave the Confederacy a realistic opportunity to create and sustain a navy to search out and seize or destroy Union ships worldwide. From Wikipedia Since Caleb Cushing’s expertise in international maritime law was well known, it was no surprise that Secretary Seward would ask him to review the laws, treaties and precedents applicable to the “Trent Affair”. Cushing found there was no exact precedent in American maritime law but there was a doctrine in British law specifically justifying the arrest in transit of ‘unarrived enemy ambassadors’. However, the most important legal point was that neutral governments must abstain from affording military aid to any recognized belligerent. Ironically, by declaring herself neutral, Great Britain had placed herself in a position which seemed to justify Captain Wilkes’ action. Even as he presented his findings - the US was indeed justified in taking and holding Mason and Slidell - Cushing was savvy enough to know there was more to this than the letter of the law. Seward must carefully balance American public opinion and British power. He needed a face-saving loophole. In the last paragraph of his memorandum Cushing’s states: “Great Britain cannot fail, I think, to perceive that, - as no offense was intended to her in the matter, and as the rights of belligerency were exercised by Capt. Wilkes in the most moderate form, without seizure of the mails, without bringing in (the Trent) as a prize, without injury to private property, - her national pride and her national honor conspire to dictate the most amicable construction of this inevitable act of sovereignty and belligerent right of the United States.” Deftly, Secretary of State Seward found the face saving loophole he needed in virtually the same argument Cushing had developed in defense of the taking and keeping of the Confederate emissaries…..the twist was to assert that Capt. Wilkes had acted “legally” but without direct authorization. Seward’s reply to Great Britain’s Lord Palmerston was, according to Wikipedia,” ’a long, highly political document.” Seward stated that Wilkes had acted on his own and denied allegations by the British that the seizure itself had been conducted in a discourteous and violent manner. The capture and search of the Trent was consistent with international law,……..but the release of the prisoners was…. required in order “to do to the British nation just what we have always insisted all nations ought to do to us.’ “ And indeed on New Year’s Day 1862 the emissaries for the Confederacy were released from Ft. Warren. As biographer Claude M. Fuess concludes “Caleb Cushing’s exposition of the principles of international law involved in the controversy was indubitably sound, and has since received the approval of the very best authority”. The US and the Lincoln administration had safely navigated around a potential international crisis. Jim Dyer is a Newburyport resident, a student of the life and times of Caleb Cushing and co-chair of the Committee to Re-discover Caleb Cushing.
