Portraits of Blue & Grey, hosted by Christopher Moore, treats the American Civil War as a story best told through the people inside it. That idea shapes the catalog in two ways. Some figures receive full multi-part portraits. William Tecumseh Sherman, Nathan Bedford Forrest and John Brown each stretch across several episodes, following Sherman through the March to the Sea and Brown to Harpers Ferry. Other episodes are built around a campaign or a theme, and there the people arrive in clusters. The Red River series brings in Nathaniel Banks, Admiral David Dixon Porter and Lt. Col. Joseph Bailey, a Wisconsin engineer who built an improvised dam. 'Raiders of the Lost Cause; Part A' and its companion follow Jeb Stuart and Jubal Early to Chambersburg, Pennsylvania. The naval war appears through the commerce raider CSS Alabama and Captain Raphael Semmes. Espionage is covered from both sides. The Union episodes cover Allan Pinkerton's privatized operation, Colonel George Sharpe's Bureau of Military Information, Elizabeth Van Lew's Richmond network and Lafayette Baker's counterintelligence bureau in Washington. The Confederate material turns to cavalry scouting, the Signal Corps and the Secret Service. It also includes smaller, vivid stories, such as Jedediah Hotchkiss mapping the Shenandoah Valley for Stonewall Jackson and the Iron Scouts' Beefsteak Raid during the siege of Petersburg. The host is willing to rule on contested evidence. Sarah Edmonds' nearly two years as Private Franklin Thompson of the 2nd Michigan are treated as solid. The spy exploits in her best-selling account are judged to be fiction, and the host calls the decision to mix the two a mistake that undercut her real record. The hanging of Sam Davis, later sung as 'the boy hero of the Confederacy', is set beside the Confederacy's own stated position on enemy spies. Primary sources are read aloud at length, bracketed by a spoken 'quote' and 'end quote'. The Copperheads episode gives a long stretch to Daniel Voorhees' furious 1872 attack on Reconstruction, alongside Pomeroy's published invective against Lincoln. Diplomacy is part of the picture too: Seward's threat of war against Britain, Britain's declaration of neutrality, and the long game London played with the Union blockade. The tone is conversational and dry. The Copperheads episode starts with pit vipers and a minor DC Comics villain before turning to anti-war Northerners. Modern comparisons, such as strategic ambiguity over Taiwan, help place unfamiliar politics. Digressions are acknowledged rather than hidden, and the host invites listener questions and comments by email.
