Guest: Patrick K. O'Donnell. This segment introduces the "Jesse Scouts," a Union special forces unit formed by John Frémont and named after his wife. Led by figures like John Charles Carpenter, these men wore Confederate disguises to infiltrate enemy lines. Despite their effectiveness as commandos, their lack of discipline led to friction with the regular Army.

Guest: Patrick K. O'Donnell. Richard Blazer leads the "Legion of Honor," a hunter-killer team using Jesse Scout tradecraft to fight Confederate partisans in West Virginia. Blazer employs detective work to track down the ruthless Thurman brothers, who attack Union supply lines in the rugged terrain of the Appalachians.

Guest: Patrick K. O'Donnell. A failed Union raid on Richmond carrying orders to kill Jefferson Davis prompts the Confederacy to escalate irregular warfare and political influence operations. As the Confederate Secret Service aids the Copperhead movement, author Herman Melville embeds with Union cavalry to witness the hunt for the elusive John Mosby.

Guest: Patrick K. O'Donnell. Confederate General Jubal Early threatens Washington, D.C., where Lincolnwitnesses the battle at Fort Stevens. Meanwhile, partisan leader John Mosby operates independently, capturing Union forces at Mount Zion Church. O'Donnell notes that better coordination between Early and Mosby could have endangered the capital.

Guest: Patrick K. O'Donnell. Grant orders total war in the Shenandoah Valley to crush Mosby's Rangers. Although Richard Blazer's scouts initially have success with Spencer carbines, they are eventually lured into a trap and annihilated by Mosby's men at Kabletown, where Blazer is captured by Ranger Lewis Powell.

Guest: Patrick K. O'Donnell. Lewis Powell, the Ranger who captured Blazer, is revealed to be a Confederate Secret Service operative working with John Wilkes Booth. Powell returns to Baltimore to aid in a plot to kidnap Lincoln, while Mosby deploys troops to secure a potential escape route for the conspirators.

Guest: Patrick K. O'Donnell. Harry Harrison Young takes command of the Jesse Scouts, serving as Sheridan'sstrategic eyes in Confederate uniforms. These daring scouts deceive enemy forces and carry messages through enemy lines, enabling Sheridan to move his army effectively to join Grant and trap Lee.

Guest: Patrick K. O'Donnell. Robert E. Lee rejects the option of guerrilla warfare at Appomattox, choosing surrender to preserve the nation. Years later, former partisan John Singleton Mosby becomes close friends with U.S. Grant and joins the Republican Party, earning the enmity of many Southerners but symbolizing reconciliation.

Guest: Michael Vorenberg. At Appomattox, Grant offers generous terms allowing Confederates to keep horses and sidearms. However, Lincoln does not immediately declare the war over; in his final speech, he focuses on the complex path to peace and suffrage, viewing the surrender as a step rather than a conclusion.

Guest: Michael Vorenberg. Following Lincoln's assassination, General Sherman negotiates a surrender with Confederate General Johnston at Bennett Place. Sherman attempts to secure a comprehensive peace including civil matters, but officials in Washington, seeking stricter retribution, reject the terms as too generous, forcing a second, purely military surrender.

Guest: Michael Vorenberg. While the Grand Review celebrates victory in Washington, General Sheridan is sent to the Texas border with 50,000 troops to counter French imperial ambitions in Mexico and suppress remaining Confederate resistance. Meanwhile, Confederate General Kirby Smith flees to Mexico rather than surrender his western forces.

Guest: Michael Vorenberg. The government utilizes military tribunals to try Lincoln's assassins and Andersonville commandant Henry Wirz, arguing the war is ongoing. Prosecutors hope to pressure Wirz into implicating Jefferson Davis in prisoner atrocities to justify hanging the Confederate president, but Wirz refuses and is executed alone.

Guest: Michael Vorenberg. Vorenberg discusses Richard Henry Dana's "Grasp of War" speech, which argued the war could not end until the victor secured guarantees against future conflict. This philosophy, demanding the enemy be held down, contrasted sharply with Lincoln's "let 'em up easy" wrestling metaphor, fueling Congressional debates over reconstruction.

Guest: Michael Vorenberg. Vorenberg explains how President Johnson's racism and desire for a hasty peace alienated Congress. Johnson vetoed the Civil Rights and Freedman's Bureau Acts, arguing the war was over. Republicans, however, insisted war powers remained necessary to protect freedmen, leading them to override Johnson and unite against him.

Guest: Michael Vorenberg. To undercut radicals, Johnson followed Seward's advice to declare the insurrection ended by executive proclamation in 1866. Vorenberg notes this "official" peace ignored realities like the New Orleans massacre. Simultaneously, Senator Doolittle was misled by General Carlton regarding the mistreatment of the Navajo at Bosque Redondo during his peace commission tour.

Guest: Michael Vorenberg. General Grant found himself caught between a hostile President Johnson and Secretary Stanton. Vorenberg describes the disastrous "swing around the circle" tour, where Johnson used Grant'spopularity as a shield while making embarrassing speeches. Witnessing Johnson's behavior, Grant ultimately sided with Stanton, realizing the President was unworthy of his loyalty.
