O’Sullivan appears to have included himself in some of his photos. I remembered having seen this particular wagon in another image recently, which turned out to have been taken in the Manassas area on July 4.

O’Sullivan also appears to have included himself in 2 other images that have already been published here:
Locomotive on the Orange & Alexandria Railroad in Virginia – in foreground with back to camera, dressed the same as in the top image.
Federal battery fording a tributary of the Rappahannock – on right side of image next to the same wagon as is in the above two images.

Title: Soldier’s dummies and quakers, left in the works at Harrison’s landing.
Alfred Waud, the artist, wrote on the back, “The soldiers tell me there was a number of these bogus guns and figures, and their appearance kept the enemy from the camp for some time after it was evacuated. The photographer has a picture of these sham guns, but it was taken before the figures were set up.”

In 1862, the Confederates had a training camp and army hospital at Culpeper Court House, and they established a supply base there early in 1862. General John Pope’s Union forces occupied the county in July 1862.
