1. The Boy Spy: A Substantially True Record of Secret Service During the War of the Rebellion. Chicago: American Mutual Library Association, 1889. Chicago: Donahue, Henneberry, 1892.
Fishel notes that the phrase "substantially true" in the subtitle "makes this book of fictions and occasional facts unique among Civil War espionage memoirs in its admission that some of its stories might be slightly embellished." (p. 603, fn. 15)
2. Further Adventures of the Boy Spy in Dixie. Washington, DC: National Tribune, 1898.
Lubet, Steven. John Brown's Spy: The Adventurous Life and Tragic Confession of John E. Cook. New Haven, CT: Yale University Press, 2012.
For Goulden, Washington Lawyer, Jul.-Aug. 2013, this "is a sprightly -- and often spicy -- portrait of Cook." Rothera, H-CivWar (Oct. 2013), notes that the author "forcefully argues in favor of studying the raiders to learn more about the men who joined Brown and to move beyond sanitized depictions. Overall, this is a well-written book that will appeal to both a scholarly and popular audience, although ... Lubet errs in placing too much responsibility for the 'death' of Southern unionism on John Brown."
Milton, David Hepburn. Lincoln's Spymaster: Thomas Haines Dudley and the Liverpool Network. Mechanicsburg, PA: Stackpole, 2003.
Seamon, Proceedings 129.9 (Sep. 2003), comments that Dudley, the U.S. consul in Liverpool, "seems to have worked almost 24 hours a day setting up an efficient spy network to keep tabs on Confederate efforts to acquire warships from British shipyards." Also, through his pamphlets and speeches, "Dudley had remarkable success in keeping the British working class firmly on the side of the Union." To Williams, Civil War Book Review [http://www.cwbr.com], this is an "engrossing, well-written story"; the author's "finely crafted work reads like a story of intrigue and deception as much as a historical text."

In 1861, Sanford "was appointed minister resident to Belgium.... One of Sanford's principal assignments ... was to prevent Confederate agents in Europe from obtaining warships, arms, munitions, and other supplies.... Sanford's principal method of countering the Confederates was to gather information on activities of theirs that violated the neutrality of the countries involved, and turn it over to the respective governments. His activities seriously damaged Confederate supply lines." O'Toole, Encyclopedia, pp. 401-402.

On 6 October 1862, McClellan appointed Brig. Gen. Marsena Patrick provost marshal general of the Army of the Potomac, "giving him broad authority and the responsibility for the security of the army." Initial duties were as the army's chief of police, but some of his duties would "lead him into intelligence work under McClellan's successors." Hooker had Patrick create a "secret service" for the army, independent of Lafayette Baker's organization in Washington. The new Bureau of Military Information focused on "producing combat intelligence" but also engaged in counterintelligence work. The bureau languished under Meade, but was reactivated when Grant decide to make his headquarters in the field with the army. "Patrick was in the thick of things" as Grant's offensive got under way. After the fall of Richmond, he was put in charge of restoring order to the former Confederate capital. He was finally relieved to return home on 9 June 1865.

"William Jackson was a slave in the home of Confederate president Jefferson Davis during the Civil War. It turns out he was also a spy for the Union Army, providing key secrets to the North about the Confederacy." The report quotes Kenneth Daigler (here misspelled as Dagler) of the CIA's Center for the Study of Intelligence and mentions Robert Smalls and Harriet Tubman as among "hundreds" who aided the Union during the war.

Security concerns to state officials included the southern border countries with Missouri and the state's vocal Copperhead minority. "Iowa's officialdom and its loyalist citizens consistently exaggerated both threats."
