The soldiers gathered in small groups each evening to prepare their food. The food was low quality for both armies, but the Confederate soldier suffered more from lack of food. For soldiers of the North, some food was obtained by plunder. When food deliveries were interrupted by weather delays or other challenges, soldiers were forced to forage the countryside to supplement their meager diets.
Many Southern soldiers simply cooked cornmeal mush around a rifle ramrod. They took the cornmeal and swirled it around in grease, making a dough. They then wrapped the dough around their rifle ramrod and cooked it over the campfire. That was called "sloosh".
