They were of both Union and Confederate soldiers using the topic of today's episode to spy on one another. Not only would they use this to observe the enemy, but they were also able to learn the terrain of the battlefield, take inventory, and even aim accordingly in the direction of the oncoming enemy. Oh, and this "spy vehicle" wasn't concealed at all. You're listening to The Story Behind: The Extraordinary History of the Ordinary.
