Some kind of propaganda seems to be going on here.
From the Richmond Daily Dispatch July 11, 1862:
Yankee Trick.
A soldier from Georgia picked up on the battlefield, a Yankee “Richmond Dispatch,” which had been dropped by some dead Yankee. We have not yet seen it, but persons who have, say it is a curi It is exactly like this paper. The size, paper, advertisements and all are precisely the same. The only difference is in the editorials. The Yankee concern is full of desponding and despairing editorials, which pronounce our cause desperate and say that McClellan is obliged to take the city. These counterfeits are no doubt sent North, and used in keeping up the popular delusion there. –Possibly, other Southern papers may be counterfeited too. Was there ever a nation so thoroughly hear?
