Unknown History's next season is still in the works, but this week, we're sharing another bonus clip. This episode is a special excerpt from the audiobook The Long Gray Line by Rick Atkinson. It tells the 25-year saga of three graduates of the West Point class of 1966. You'll follow them from their boisterous cadet years to the fires of Vietnam to the hard peace and internal struggles that followed the war. Get your copy today here or wherever books are sold.
