In 1864, the American Civil War reached a critical juncture with Ulysses S. Grant’s Overland Campaign, including the brutal battles of the Wilderness and Spotsylvania, which claimed over 60,000 casualties, surpassing Gettysburg as the Americas’ deadliest clash. Abraham Lincoln faced a contentious re-election against George B. McClellan, while Confederate General Jubal Early’s troops came within five miles of the White House. Abolitionists pushed for emancipation, and desperate Confederate plots, like the attempt to burn New York City’s hotels, marked the war’s final months, culminating in Lincoln’s assassination by John Wilkes Booth in April 1865.

Today’s guest is Scott Ellsworth, author of “Midnight on the Potomac: The Last Year of the Civil War, the Lincoln Assassination, and the Rebirth of America.” We explore how the staggering losses of 1864 shaped Lincoln’s strategy of attrition amid political uncertainty. These include lesser-known moments, like the Washington Arsenal explosion that killed 21 workers and Early’s near-invasion of Washington, D.C., which could have altered the war’s course. We also examines the November 1864 Confederate plot to destabilize New York and the conspiracy behind Lincoln’s assassination, including the unresolved question of Confederate government involvement. Reflecting on the war’s toll—over 620,000 dead and four million African-Americans freed but facing new struggles—Ellsworth illuminates how these events reshaped America’s identity.

Camp David, nestled in Maryland’s Catoctin Mountains, spans about 125 acres, making it significantly smaller than other presidential getaways like Lyndon B. Johnson’s sprawling 2,700-acre Texas ranch or the vast 1,000-acre Bush family compound in Kennebunkport, Maine. Compared to grand diplomatic venues like the White House or international summit locations such as Versailles, its compact, rustic layout with a single main lodge and a handful of cabins offers a more intimate, secluded setting for negotiations. This modest size fosters privacy and informality, as seen during the 1978 Camp David Accords, but lacks the expansive facilities of larger estates or formal state venues.

If that’s the case, why has it played host to the most important diplomatic summits of the 20th century? Because the hidden retreat is the one place the President, First Family, and invited guests can gather in absolute secrecy for relaxation, rejuvenation, and world-changing decisions.

Today’s guest is Charles Ferguson, author of “Presidential Seclusion: The Power of Camp David.” We look at the importance of Camp David on diplomacy and world history. Written by the former Camp David Historian, this personalized tour of the exclusive retreat makes tree-shrouded trails, majestic vistas, and rooms where history happened over the last 80 years.

In August 1942, over 7,000 Allied troops stormed the beaches of Normandy, France, in a largely forgotten landing, with only a small fraction surviving unscathed. The raid failed due to poor planning and lack of underwater reconnaissance, which left the Allies unaware of strong German coastal defenses and underwater obstacles. Inadequate submersible technology prevented effective pre-landing surveys, leading to heavy casualties and the inability to secure a foothold. Scientists had a rudimentary grasp of mixing air for prolonged underwater survival, with limited rebreather technology, poor understanding of oxygen toxicity, and inadequate gas supply systems.

Two summers before D-Day, the Allies realized they desperately needed underwater intelligence to succeed in another beach invasion and win the war. Led by controversial biologists J.B.S. Haldane and Dr. Helen Spurway, an ingenious team of ragtag scientists worked in makeshift labs throughout the London Blitz. Amid a rain of bombs, they pioneered groundbreaking advances in underwater reconnaissance through painful and potentially fatal self-experiments. Their discoveries enabled the safe use of miniature submarines and breathing apparatuses, ultimately allowing the Allies to take the beaches of Normandy.

Blast-injury specialist Dr. Rachel Lance, author of Chamber Divers: The Untold Story of the D-Day Scientists Who Changed Special Operations Forever, joined us a few years ago to discuss the CSS Hunley, a Confederate submersible used during the American Civil War, the first submarine to sink an enemy ship in combat. We explore these experiments while bringing to life the men and women whose brilliance and self-sacrifice shaped the war’s outcome, including the danger they faced in their quest to enable Allied troops to breathe underwater.

The Allied Intervention into the Russian Civil War remains one of the most ambitious yet least talked about military ventures of the 20th century. Coinciding with the end of the first World War, some 180,000 troops from several countries including the United States, the United Kingdom, France, Japan, Italy, Greece, Poland, and Romania, among others, were sent to fight alongside Russian “Whites” against the Red Army.

Despite one victory for the Allied troops – independence for the Latvians and the Estonians – the two-year long attempt at reversing the 1917 Russian Revolution ended in humiliating defeat. To explore this crucial event of the early 20th century is today’s guest, Anna Reid, author of “A Nasty Little War: The Western Intervention into the Russian Civil War.”

What was originally aimed to prevent Germany from exploiting the power vacuum in Eastern Europe left by the Russian Revolution ultimately morphed into the Allies’ gamble to destroy Communist ideology. It was a mixture of good intentions and self-delusion, flag-waving and empty promises, cover-ups, exaggerations, and downright lies from politicians.

During World War II, the U.S. and Japan were locked in bitter hatred, fueled by propaganda portraying each other as ruthless enemies, exemplified by dehumanizing "Tokyo Woe" posters in the U.S. and Japanese depictions of Americans as barbaric invaders. After the war, the feelings seemed to turn 180 degrees overnight. By the early 1950s, American servicemen in the occupying forces learned about Japanese tea ceremonies and traditions during the U.S. occupation, fostering cultural appreciation. By the 1950s, dishes like teriyaki and sukiyaki became popular in America, with Kyu Sakamoto’s 1963 hit song “Sukiyaki” topping U.S. charts, signaling a growing fascination with Japanese culture. This led the way to the Japanese automotive and electronics invasion a decade later, with brands like Nikon, Canon, and Toyota crushing the domestic market. How did sentiments between the nations change so quickly?

Much of it has to do with the success of the American occupation of Japan after the war, which rebuilt Japan’s economy and fostered mutual respect. To explain this period is today’s guest, Christopher Harding, author of “A Short History of Japan.” We look at Japan’s own view of its past, the transformative policies of General Douglas MacArthur’s administration that democratized and modernized Japan, the role of cultural exchanges in softening mutual perceptions, and how Japan’s rapid post-war recovery laid the groundwork for its emergence as a global economic power by the 1960s.

The Iliad is the world’s greatest epic poem—heroic battle and divine fate set against the Trojan War. Its beauty and profound bleakness are intensely moving, but great questions remain: Where, how, and when was it composed and why does it endure?

To explore these questions is today’s guest, Robin Lane Fox, a scholar and teacher of Homer for over 40 years. He’s the author of “Homer and His Iliad” and he addresses these questions, drawing on a lifelong love and engagement with the poem. He argues that the poem is the result of the genius and single oral poet, Homer, and that the poem may have been performed even earlier than previously supposed a place, a date, and a method for its composition—subjects of ongoing controversy. Lane Fox considers hallmarks of the poem; its values, implicit and explicit; its characters; its women; its gods; and even its horses.

In the 1930s, New Deal-era technocrats devised a solution to homelessness and poverty itself. They believed that providing free or low-cost urban housing projects could completely eliminate housing scarcity. Planners envisioned urban communities that would propel their residents into the middle class, creating a flywheel of abundance where poverty was eradicated. However, once construction began after World War II, these projects quickly became dangerous, poorly maintained slums, serving as breeding grounds for crime and decay. By the 1970s, crime rates were so high that levels of violence rivaled those of war zones in Sub-Saharan Africa.

What happened? Why did so many of the best and brightest who promoted housing projects—like First Lady Eleanor Roosevelt or city planner Robert Moses—create one of the worst government debacles of the 20th century? Why didn’t they foresee that housing projects would become hotbeds of crime, completely destroying the social fabric of the neighborhoods they aimed to help? Today’s guest is Howard Husock, author of “The Projects: A New History of Public Housing.” He explains how we got here, detailing the tragic rise and fall of public housing and the pitfalls of other subsidy programs. He takes us inside a progressive movement led by a group of New York City philanthropists, politicians, and business magnates who first championed public housing as a solution to urban blight. We explore everything that went wrong and what can be done to avoid these same mistakes in the future.

As the popular narrative goes, the Civil War was won when courageous Yankees triumphed over the South. But an aspect of the war that has remained little-known for 160 years is the Alabamian Union soldiers who played a decisive role in the Civil War, only to be scrubbed from the history books. One such group was the First Alabama Calvary, formed in 1862. It went on raids that destroyed Confederate communications and also marched with Sherman’s forces across the South. They aided the fall of Vicksburg and the burning of Atlanta.

Today’s guest is Howell Raines, author of “Silent Cavalry: How Union Soldiers from Alabama Helped Sherman Burn Atlanta—and Then Got Written Out of History.” As Raines has pieced together, Union General William Tecumseh Sherman’s decisive effort to burn Atlanta was facilitated by an unsung regiment of 2,066 yeoman farmers and former slaves from Alabama—including at least one member of Raines’s own family.

So why have the best-known Civil War historians, including Ken Burns and Shelby Foote, given only passing – or no – attention to this regiment of southerners who chose to fight for the North – a regiment that General Sherman hailed as one of the finest in the Union? We explore this question through an account of Alabama’s Mountain Unionists and their exploits, along with investigating why they and others like them were excised from the historical record.
