On January 30, 1918, a young man “with the appearance of a well-educated, debonair foreigner” arrived at the U.S. customs station in Nogales, Arizona, located on the border with Mexico. After politely informing the customs inspector that he had come to complete his draft registration questionnaire and meet a friend in San Francisco, he was approved to cross the border into the United States. Lothar Witzke, the most dangerous German agent in the western hemisphere had reached his destination. His assignment: launch a campaign of sabotage, insurrection, and murder to destabilize the American home front.The terror campaign would be devastating - unless it could be stopped by U.S. counterintelligence.The Witzke mission was the intelligence game played at its highest level - a plan for destruction on a massive scale, violent insurrection, and assassination, complete with master spies and double agents, diabolical sabotage devices, secret codes, and invisible ink.To look at these forgotten elements of German sabotage and assassination plots in the United States during World War One is today’s guest, Bill Mills, author of “Agents of the Iron Cross.”

WW1 German Spies Infiltrated America and Attempted to Start a Race War

For history lovers who listen to podcasts, History Unplugged is the most comprehensive show of its kind. It's the only show that dedicates episodes to both interviewing experts and answering questions from its audience. First, it features a call-in show where you can ask our resident historian (Scott Rank, PhD) absolutely anything (What was it like to be a Turkish sultan with four wives and twelve concubines? If you were sent back in time, how would you kill Hitler?). Second, it features long-form interviews with best-selling authors who have written about everything. Topics include gruff World War II generals who flew with airmen on bombing raids, a war horse who gained the rank of sergeant, and presidents who gave their best speeches while drunk.

Before 9/11, before Pearl Harbor, another unsuspected foreign attack on the United States shocked the nation and forever altered the course of history. In 1916, Pancho Villa, a guerrilla fighter who commanded an ever-changing force of conscripts in northern Mexico, attached a border town in New Mexico. It was a raid that angered Americans, and President Woodrow Wilson ordered the Punitive Expedition in which the US Army invaded Mexico and defeated General Villa's troops, but failed to capture him. This event may have been the catalyst for America’s entry into World War One and permanently altered U.S.-Mexican border policy.Jeff Guinn, author of the new book "War on the Border," joins us to discuss this critically important event in American history. The “Punitive Expedition” was launched in retaliation under Pershing’s command and brought together the Army, National Guard, and the Texas Rangers—who were little more than organized vigilantes. The American expedition was the last action by the legendary African-American “Buffalo Soldiers.” It was also the first time the Army used automobiles and trucks, which were of limited value in Mexico, a country with no paved roads or gas stations. Curtiss Jenny airplanes did reconnaissance, another first. One era of warfare was coming to a close as another was beginning. But despite some bloody encounters, the Punitive Expedition eventually withdrew without capturing Villa.Although the bloodshed has ended, the US-Mexico border remains as vexed and volatile an issue as ever.

Pancho Villa’s 1916 Raid on New Mexico: The Pearl Harbor Bombing of Its Time

At the start of the 1860 presidential campaign, a handful of fired-up young Northerners appeared as bodyguards to defend anti-slavery stump speakers from frequent attacks. The group called themselves the Wide Awakes. Soon, hundreds of thousands of young white and black men, and a number of women, were organizing boisterous, uniformed, torch-bearing brigades of their own. These Wide Awakes—mostly working-class Americans in their twenties—became one of the largest, most spectacular, and most influential political movements in our history. To some, it demonstrated the power of a rising majority to push back against slavery. To others, it looked like a paramilitary force training to invade the South.Today’s guest, Jon Grinspan (author of “Wide Awake: The Forgotten Force That Elected Lincoln and Spurred the Civil War”) examines how exactly our nation crossed the threshold from a political campaign into a war. We look at the precarious relationship between violent rhetoric and violent actions.

A Radical Abolitionist Youth Movement Consumed America in 1860, Elected Lincoln, Then Disappeared Completely

The influence of the ancient Greek philosopher Socrates has been profound. Even today, over two thousand years after his death, he remains one of the most renowned humans to have ever lived—and his death remains one of the greatest unsolved mysteries.  There is another side to this story: impiety, lack of reverence for the gods, was a religious crime. From the perspective of the religious authorities of the time, the charge of impiety against Socrates was warranted. The priests did not tolerate scrutiny, even in the form of philosophical critique. To understand what happened and how it happened, we have to come to terms with the motives of the priests, and as importantly, Socrates’ motives in provoking them. His trial is perhaps first, but not last, great battle between philosophy and religion.To explore this mystery is today’s guest, Matt Gatton, author of “The Shadows of Socrates.”

Socrates May Have Been Executed For Revealing Secrets of Athens’ Religious Rituals

A millennium ago, North American cities rivaled urban centers around the world in size. So, when Europeans arrived in the sixteenth century, they encountered societies they did not understand, having developed differently from their own, and whose power they often underestimated. And no civilization came to a halt when a few wandering explorers arrived, even when the strangers came well-armed.To explore this overlooked history is today’s guest, Kathleen DuVal, author of “Native Nations.” For centuries after these first encounters, Indigenous people maintained an upper hand and used Europeans in pursuit of their own interests. In Native Nations, we see how Mohawks closely controlled trade with the Dutch--and influenced global markets--and how Quapaws manipulated French colonists.Power dynamics shifted after the American Revolution, but Indigenous people continued to control the majority of the continent. Shawnee brothers Tecumseh and Tenskwatawa forged new alliances and encouraged a controversial new definition of Native identity to attempt to wall off U.S. ambitions. The Cherokees created new institutions to assert their sovereignty on the global stage, and the Kiowas used their preponderance of power in the west to regulate the passage of white settlers across their territory.

War, Conflict, Victory & Defeat. These are all aspects of life that some may have to face. This was true for the various groups of the Sioux Tribes.
