As many as 100,000 enslaved people fled successfully from the horrors of bondage in the antebellum South, finding safe harbor along a network of passageways across North America via the Underground Railroad. Yet many escapes took place not by land but by sea. William Grimes escaped slavery in 1815 by stowing away in a cotton bale on a ship from Savannah to New York, enduring days without food or water before settling in Connecticut. Frederick Douglass disguised himself as a free black sailor, using borrowed papers to board a train and then a steamboat from Baltimore to New York, reaching freedom in less than 24 hours. Thomas Jones, a formerly enslaved man from North Carolina, escaped in 1849 by hiding on a ship bound for New York, relying on his maritime knowledge as a steward to evade detection and later reuniting with his family in the North.This was a secret world of stowaways and the vessels that carried them to freedom across the North and into Canada. It sprawled through the intricate riverways of the Carolinas to the banks of the Chesapeake Bay to Boston’s harbors.  Today’s guest is Marcus Rediker, author of “Freedom Ship: The Uncharted History of Escaping Slavery by Sea.”  We see the Atlantic waterfront as a place of conspiracy, mutiny, and liberation.See omnystudio.com/listener for privacy information.

2025 marks the eightieth anniversary of Germany’s surrender and the fall of the Third Reich. Likewise, World War II is the single most studied conflict in human history. But most Western accounts offer a one-dimensional interpretation: the war was a noble crusade against fascism, creating a convenient parable about good and evil. But this depiction ignores a far messier reality. But what went through the minds of the actual heads of state that led their nations through the war? Did they fight according to our understanding, or did they want to defend their nations’ global empires and ancient legacy? A case can be argued that   World War II was not a battle in which democracy triumphed over totalitarianism but rather a massive colonial war waged by rival empires. The war formally ended the era of British and Japanese colonialism but established in their places the highly militarized Soviet and American states, whose access to nuclear weapons threatened the possibility of annihilation. As we grapple with the legacy of the war and its influence on geopolitics today, historian and today’s guest Paul Thomas Chamberlin urges us to reconsider the conflict from a new perspective in his book “Scorched Earth: A Global History of World War II.”See omnystudio.com/listener for privacy information.

As the American Revolution broke out in New England in the spring of 1775, dramatic events unfolded in Virginia that proved every bit as decisive as the battles of Lexington and Concord and Bunker Hill in uniting the colonies against Britain. Virginia, the largest, wealthiest, and most populous province in British North America, was led by Lord Dunmore, who counted George Washington as his close friend. But the Scottish earl lacked troops, so when patriots imperiled the capital of Williamsburg, he threatened to free and arm enslaved Africans—two of every five Virginians—to fight for the Crown. Virginia’s tobacco elite was reluctant to go to war with Britain but outraged at this threat to their human property. Dunmore fled the capital to build a stronghold in the colony’s largest city, the port of Norfolk. As enslaved people flocked to his camp, skirmishes broke out. “Lord Dunmore has commenced hostilities in Virginia,” wrote Thomas Jefferson. “It has raised our countrymen into a perfect frenzy.” With a patriot army marching on Norfolk, the royal governor freed those enslaved and sent them into battle against their former owners. In retribution, and with Jefferson’s encouragement, furious rebels burned Norfolk to the ground on January 1, 1776, blaming the crime on Dunmore. The port’s destruction and Dunmore’s emancipation prompted Virginia’s patriot leaders to urge the Continental Congress to split from Britain, breaking the deadlock among the colonies and leading to adoption of the Declaration of Independence. Days later, Dunmore and his Black allies withdrew from Virginia, but the legacy of their fight would lead, ultimately, to Abraham Lincoln’s 1863 Emancipation Proclamation. Chronicling these stunning and widely overlooked events in full for the first time is today’s guest, Andrew Lawler, author of A Perfect Frenzy: A Royal Governor, His Black Allies, and the Crisis that Spurred the American Revolution. He offers a new perspective on the American Revolution that reorients our understanding of its causes, highlights the radically different motivations between patriots in the North and South.See omnystudio.com/listener for privacy information.

He was a gutsy old man.” “A corker,” said another. “You couldn’t find anyone better.” They talked about him in hushed tones. “This Major Carlson,” wrote one of the officers in a letter home, “is one of the finest men I have ever known.”These were the words of the young Marines training to be among the first U.S. troops to enter the Second World War—and the Major Carlson they spoke of was Evans Carlson, a man of mythical status even before the war that would make him a military legend.By December of 1941, at the age of forty-five, Carlson had already faced off against Sandinistas in the jungles of Nicaragua and served multiple tours in China, where he embedded with Mao’s Communist forces during the Sino-Japanese War. Inspired by their guerilla tactics and their collaborative spirit—which he’d call “gung ho,” introducing the term to the English language—and driven by his own Emersonian ideals of self-reliance, Carlson would go on to form his renowned Marine Raiders, the progenitors of today’s special operations forces, who fought behind Japanese lines on Makin Island and Guadalcanal, showing Americans a new way to do battle.Today’s guest is Stephen R. Platt, author of “  “The Raider: The Untold Story of a Renegade Marine and the Birth of U.S. Special Forces in World War II.” Tracing the rise and fall of an unlikely American war hero, The Raider is a story of exploration, of cultural (mis)understanding, and of one man’s awakening to the sheer breadth of the world.See omnystudio.com/listener for privacy information.

In this engaging conversation, Thomas Levenson, author of "So Very Small," uncovers the intriguing history of microbes and public health. He explains why it took over 200 years for the medical community to link germs to disease, despite their early discovery. Levenson highlights revolutionary figures like Edward Jenner and Florence Nightingale, whose innovations shifted public health from ignorance to action. He also touches on the antibiotic era, emphasizing the urgent need for responsible use as resistance grows, reminding us of the ongoing battle against infectious diseases.

The story of the atomic age began decades before Robert Oppenheimer watched a mushroom cloud form over the New Mexico desert at the Trinity nuclear test in mid 1945. It begins in 1895, with Henri Becquerel’s accidental discovery of radioactivity, setting in motion a series of remarkable and horrifying events. By the early 20th century, a brilliant group of scientists—including Ernest Rutherford, Leo Szilard, Enrico Fermi, and others—were pushing the boundaries of knowledge, seeking to answer fundamental questions about this source of energy that had 2 million times the energy density of oil: What is this mysterious radiation? Could it provide an infinite energy source, where a basketball of it was equal to an oil field? And, ominously, could it be weaponized? Today’s guest is nuclear physicist Frank Close, author of “Destroyer of Worlds: The Deep History of the Nuclear Age.” We look at the complete history of the atomic age, from the initial curiosity about radioactivity to the creation of the hydrogen bomb—a weapon of almost unimaginable destructive potential, capable of eradicating life on Earth. This is an account of the scientific discoveries that unlocked the atom’s power, the ethical dilemmas faced by scientists, and the horrifying realization that this newfound energy could lead to humanity’s undoing.See omnystudio.com/listener for privacy information.

The B-29 Bomber led the Allied strategic bombing offensive against Japan, succeeding when US Bomber Command switched from high-level daytime precision bombing to low-level nighttime area bombing. The latter tactic required Superfortresses to attack their targets individually, without a formation or escorting fighters for protection. Despite this, Japanese night fighters proved unable to stop the B-29s. This success was a testament to the B-29’s incredible capabilities, including its ability to carry up to 20,000 pounds of bombs over vast distances exceeding 3,000 miles, and its advanced pressurized cabin, which allowed crews to operate effectively at altitudes above 30,000 feet—far beyond the reach of most enemy interceptors. Coupled with its sophisticated remote-controlled gun turrets and a top speed of 350 mph, the B-29’s design showcased an unmatched blend of range, payload, and defensive prowess that overwhelmed Japanese defenses. Today’s guest, Mark Lardas, author of “B-29 Superfortress vs Japanese Nightfighter.” He examines the capabilities of the aircraft involved, and reveals the conditions under which both sides fought. He evaluates the cutting-edge technology of both sides and how it affected the outcome of the battleSee omnystudio.com/listener for privacy information.

Throughout the war on the Eastern Front, there were two consistent trends. The Red Army battled to learn how to fight and win, while involved in a struggle for its very survival. But by 1944 it had a leadership that was able to wield it with lethal effect and with far more effective equipment than before. By contrast, the Wehrmacht had commenced a slow process of decline after the invasion of the Soviet Union. Hitler became increasingly unwilling to delegate decision-making to commanders in the field, which had been crucial to earlier success. The long years of fighting had also taken a heavy toll. Thousands of irreplaceable junior officers and NCOs were dead, wounded or prisoners.Today’s guest is Prit Buttar, author of “Bagration 1944: The Great Soviet Offensive.” We look at these trends, which culminated in the huge battles of Bagration. In 1944, the Red Army finally put together a campaign that utterly destroyed the German Army Group Centre. The Wehrmacht suffered the loss of over 300,000 men killed, wounded or taken prisoner and the Red Army rolled forward across Belarus to the outskirts of Warsaw. The end of the war was still many months away, and the Germans managed to reconstruct their line on the Eastern Front, but final victory for the Soviet Union was now only a matter of time as a direct consequence of Bagration.See omnystudio.com/listener for privacy information.

Pilgrimages are a universal phenomenon, from China’s bustling Tai Shan to the ancient Jewish treks to Jerusalem. But why? What is it about a grueling penitent march to an isolated temple that has become a prerequisite for a civilization of any size, whether Chicen Itza in the Mayan Empire or the holy sites of Mecca? To explore this is today’s guest, Kathryn Hurlock, author of “Holy Places: How Pilgrimages Changed the World.” We also look at whether pilgrimages have become too easy in the 21st century. Has jetting off to Mecca or Rome for a quick indulgence turned them into spiritual tourism, a la Disneyland?See omnystudio.com/listener for privacy information.

Michael Jarvis, a historian and archaeologist known for his extensive work on Bermuda, reveals the island's surprising significance in colonial America. He discusses how Bermuda became England’s first profitable plantation by pioneering tobacco cultivation and using enslaved labor. With insights from his 14 years of archaeological work, he highlights Bermuda's role in supplying Jamestown and its influence on early colonial practices. Jarvis argues that far from being a mere footnote, Bermuda is a crucial cornerstone of America's origin story.
