Union accounts of what foodstuffs they captured in guerrilla camps of west-central Missouri tell about large amounts of bacon and plain country fare as supplied by the large numbers of southern sympathizers that lived there. I recall reading that on one occasion some of Quantrill's men raided a mill about brought back large amounts of flour which Union patrols kept encountering as traces fell on the ground and at campsites for days afterward. Basically, the guerrillas ate what the locals ate, freely given by southerners and taken from unwilling northerners. Local residents knew it was foolhardy in the extreme to attempt to refuse food to passing combatants of either side, but it didn't take long for farmers to hide something so their own families wouldn't starve. Food was no problem in areas where guerrillas had many friends, but harder to acquire in area where more residents were northern in sympathy. This may be one of the reasons that the west-central Missouri guerrillas wore Union uniforms when they had to travel long distances. I would assume that for a long trip guerrillas and their friends would prepare in advance food that would travel well--the same kind of food that hunters would take when out for more than a day or two.
