What a creative way to describe watery broth, "Shadow Soup"... and then there were those soldiers (and families), who had nothing which might make a shadow, and no salt, much less pepper. What did they eat? Gleanings from the woods, herbs, nuts and seeds.
Hard times, the War... for all.
What would today's families do, if war conditions erupted again... with no restaurants or Red Cross, no government benefits, no food at the local grocers? Would today's young people find food in the woods, know what is edible or poison? And where are those herbs and healthy forests of the Civil War era? Gone with acid rain, diseases, pests. We've paved paradise, and put up a parking lot.
