"Picket guard on the alert, near Lewinsville, Va." Union soldiers in front of a lean-to shelter posing as if they were fighting in a skirmish, 1861. By Edward Bierstadt. Animated stereoviews. Later used as a reference for his brother Albert Bierstadt's painting seen here:

"Guerrilla Warfare," by Albert Bierstadt, 1862. Source.

I have come across at least two other versions of Union soldiers posing in front of the shelter by Edward Bierstadt. The following stereoview is from Lincoln in Photographs: An Album of Every Known Pose.

"Picket Guard at rest near Lewinsville, Va." Another scene of Union soldiers posing in front of the shelter.

The third is said to show Union soldiers guarding Confederate POWs in front of the shelter.

"Picket Guard with Prisoners Near Lewisville." The resolution of the photograph is too low to tell whether or not the "Lewisville" caption is misspelled. From Cowan's Auctions. Source.
