Lincoln's Spymaster:
Thomas Haines Dudley
and the Liverpool Network

Lincoln's Spymaster: Thomas Haines Dudley and the Liverpool Network reminds us that more was going on during the Civil War than bloody battles dividing families along North-South lines. The Confederacy looked overseas for aid from other countries to help win the war. Receiving such aid would help establish its legitimacy, both during and after the war, as a nation in its own right. In addition to the potential for British intervention on the side of the South, the North suffered the parallel threat of an advanced Confederate navy that could be built in British shipyards, harbors safe from Northern aggression. Liverpool and London became strategic points for Northern diplomacy and espionage to prevent or curtail such Southern advantages. As the war progressed, England continued to consider intervention on the side of the South but the efforts of American Thomas Haines Dudley, Lincoln's spymaster, prevented quick action.

For Thomas Haines Dudley, who had arrived in Liverpool as U.S. consul in November 1861, the threat of British intervention was a very real and unrelenting one. Liverpool was Britain's major port city and a Confederate stronghold. James Dunwoody Bulloch was in charge of the South's Secret Service in the British Isles and he was determined to construct the most advanced naval vessels ever built. Dudley and Bulloch engaged in classic espionage dueling as the two struggled to thwart each other. While Bulloch endeavored to build ships, Dudley established an intelligence network to uncover detailed information about Southern warship construction in Great Britain and identification of blockade runners chartered for Confederate use. In the end, Dudley would completely infiltrate the Confederate network in Great Britain. He also directed a counter-intelligence watch on his spies to ensure that none of them were double agents for the Confederacy.

In early 1863, with public opinion turning to favor the North, Dudley participated in a propaganda war against Confederate sympathizers in England. Northern military victories at Vicksburg, Mississippi, and Gettysburg, Pennsylvania, in the summer of 1863, further undermined the Confederacy's cause in England. Still, Confederate ships continued to destroy Union ships and wrecked havoc on the sea until the South's two main ships carrying the Laird Rams (in violation of Foreign Enlistment Act)--the Florida and the Alabama--were put out of commission in June and October 1864, respectively.

The Civil War was not confined to American soil but reached overseas to England. Diplomatic battles, intelligence gathering, and swaying British public opinion against the Confederacy were all tactics used to win the war and keep the states united. Thomas Haines Dudley was key to the Union's success. The author brings Dudley and nineteenth century spy networks to life in a short (146 pages) but informative and thoroughly readable narrative.
