An unforgettable human drama deep with contemporary resonance, award-winning historian James Carl Nelson's The Polar Bear Expedition draws on an untapped trove of firsthand accounts to deliver a vivid, soldier's-eye view of an extraordinary lost chapter of American history—the Invasion of Russia one hundred years ago during the last days of the Great War.  Jim Nelson discusses with host Jim Fausone the hardships the American troops faced, the confused mission, the Bolshevik Army resistance and the withdrawal 7 months after WWI ended.
