5. Outlaws and Intelligence

[Spycraft Podcast Host]

Welcome to Spycraft, a podcast that tells gripping life and death spy stories and the amazing devices and operations that made them possible. Now let's get started.

[Spycraft Podcast Male Narrator]

Were there Spies during the Era of the Wild West?

[Spycraft Podcast Female Narrator]

The Wild west era, which roughly spanned the mid 19th centuries or early 20th

[Spycraft Podcast Male Narrator]

centuries, was a time of lawlessness, conflict and rapid expansion in the western regions of the U.S. the concept of traditional

[Spycraft Podcast Female Narrator]

espionage may not have been as prevalent as it is in today's world, but

[Spycraft Podcast Male Narrator]

there were instances of intelligence gathering and covert activities.

[Spycraft Podcast Female Narrator]

Let's take a look at some of

[Spycraft Podcast Male Narrator]

the examples of spies and espionage activities

[Spycraft Podcast Female Narrator]

in the the Wild West. First we look at the Pinkerton Detective Agency, which was founded by allan Pinkerton in 1850. It played a significant role in gathering

[Spycraft Podcast Male Narrator]

intelligence and conducting investigations during the Wild west era.

[Spycraft Podcast Female Narrator]

The agency was known for its detective

[Spycraft Podcast Male Narrator]

work in providing security services, but they were also involved in tracking down outlaws, gathering information, and infiltrating criminal organizations. Their work often involved undercover ops and surveillance. Number two we look at the Union and Confederate spies. During the American Civil War, spies from both the Union and Confederate armies operated in the Wild they gathered information about enemy troop movements, supply routes, and other critical intelligence. One example was James Wild Bill Hickok, who worked as a Union scout and spy, and John Slidell, a Confederate diplomat who sought to gain support from French authorities in the West. 3 We look at the Native American scouts that played a crucial role in

[Spycraft Podcast Female Narrator]

intelligence gathering for the U.S. army during

[Spycraft Podcast Male Narrator]

conflicts with Native American tribes. Many tribes have their own methods of COVID information exchange which were utilized by the U.S. army. Scouts such as Apache leader Geronimo and Lakota Sioux Chief Red Cloud, provided intelligence on many enemy movements, ambushes and tribal alliances. How about the outlaws? Outlaws and bandits also engaged in covert activities. They gathered information on law enforcement activities or rival gangs. They often operated in secretive networks and used informants to gain insights into their adversaries plans. However, it's important to note that activities were primarily focused on criminal pursuits rather than traditional espionage. Another unlikely group you might not think of much about is Cattle rustlers. Cattle rustling was a common crime in the Wild west, and rival groups often engaged in stealing or illegally branding livestock. In some instances, rival cattle rustlers would infiltrate each other's groups or pose as legitimate cowboys to gather information about herds and their owners.

[Spycraft Podcast Female Narrator]

You can see a lot of the

[Spycraft Podcast Male Narrator]

information

[Spycraft Podcast Female Narrator]

was actually

[Spycraft Podcast Male Narrator]

to gather intel, usually

[Spycraft Podcast Female Narrator]

on the opposing side. And that's where we see this espionage work really coming into fruition. But if we look at more specifics, it becomes complicated again, because it depends. But John Slidell is one that comes to mind.

[Spycraft Podcast Male Narrator]

He was most known for his diplomatic

[Spycraft Podcast Female Narrator]

efforts on behalf of the Confederacy during the Civil War. Some of his espionage escapades, including 1861. Shortly after the start of the Civil

[Spycraft Podcast Male Narrator]

War, Slidell was dispatched as a Confederate diplomat to Europe.

[Spycraft Podcast Female Narrator]

His mission was to secure diplomatic recognition and support for the Confederacy. As part of his mission, Slidell sought

[Spycraft Podcast Male Narrator]

to gather intelligence on the Union's efforts to prevent Confederate trade and garner information

[Spycraft Podcast Female Narrator]

about Union military activities.

[Spycraft Podcast Male Narrator]

While in Europe, he established a network of Confederate agents and spies who operated covertly to obtain valuable information.

[Spycraft Podcast Female Narrator]

One of the most famous espionage endeavors of his took place in France, where he established contact with a French naval

[Spycraft Podcast Male Narrator]

officer named Armand de Montmorin, who sympathized

[Spycraft Podcast Female Narrator]

with the Confederate cause.

[Spycraft Podcast Male Narrator]

Mont Marine shared valuable intelligence on the

[Spycraft Podcast Female Narrator]

Union blockade and provided Slidell with detailed

[Spycraft Podcast Male Narrator]

information about Union naval operations and strategies.

[Spycraft Podcast Female Narrator]

Utilizing the gathered intelligence, Slidell drafted reports and dispatched them back to the Confederacy. These reports were instrumental in enabling the Confederate government to understand the Union's actions and adjust their strategies accordingly. Slidell's espionage activities, though, were not without risk. Union spies were actively monitoring his movements, aware of his diplomatic mission and suspected involvement in gathering intelligence. On his return journey to the Confederacy, Slidell attempted to slip past Union authorities, but he was captured by the USS San Jacinto, commanded by Charles Wilkes. This was known as the Trent Affair, sparked an international diplomatic crisis between the US And Britain. As Slidell was traveling on the British mail ship the RMS Trent, the British government demanded the release of Slidell and his fellow Confederate diplomat James Mason, as they consider the capture a violation of the neutral rights. Ultimately, to avoid an international conflict, President Lincoln released Slidell and Mason.
