Trent Affair

Trent Affair On 8 November 1861, Captain Charles Wilkes, commanding the US warship San Jacinto, halted the British mail steamer Trent. Wilkes apprehended John Slidell and James Mason, Confederate envoys sailing for Britain, and had them detained at Boston. The seizure aroused militant anti-US sentiment in Britain, whose press called for armed retaliation. To prevent the Confederacy from reaping any further diplomatic or military advantages from the controversy, on 26 December, William Seward ordered Mason and Slidell released. US relations with Britain thereafter improved.
