A historians new look at how Union blockades brought about the defeat of a hungry Confederacy In April 1861, Lincoln ordered a blockade of Southern ports used by the Confederacy for cotton and tobacco exporting as well as for the importation of food. The Army of the Confederacy grew thin while Union dinner tables groaned and Northern canning operations kept Grants army strong. In Starving the South, Andrew Smith takes a gastronomical look at the wars outcome and legacy. While the war split the country in a way that still affects race and politics today, it also affected the way we eat: It transformed local markets into nationalized food suppliers, forced the development of a Northern canning industry, established Thanksgiving as a national holiday and forged the first true national cuisine from the recipes of emancipated slaves who migrated north.
