John D. Billings in Hardtack & Coffee (an excellent memoir detailing day-to-day life in the Army of the Potomac) briefly mentions soldiers making fritters or pancakes:

Towards the end of the war sutlers kept self-raising flour, which they sold in packages of a few pounds. This the men bought quite generally to make into fritters or pancakes. It would have pleased the celebrated four thousand dollar cook at the Parker House, in Boston, could he have seen the men cook these fritters. The mixing was a simple matter, as water was the only addition which the flour required, but the fun was in the turning. A little experience enabled a man to turn them without the aid of a knife, by first giving upward and forward. This threw the cake out and over, to be caught again the uncooked side down — all in a half-second. But the miscalculations and mishaps experienced in performing this piece of culinary detail were numerous and amusing, many a cake being dropped into the fire, or taken by a sudden puff of wind, just as it got edgewise in the air, and whisked into the dirt.
