The Lower Mississippi Valley is more than just a distinct geographical region of the United States; it was central to the outcome of the Civil War and the destruction of slavery in the American South. Beginning with Lincoln's 1860 presidential election and concluding with the final ratification of the Thirteenth Amendment in 1865, Freedom's Crescent explores the four states of this region that seceded and joined the Confederacy: Tennessee, Mississippi, Arkansas, and Louisiana. By weaving into a coherent narrative the major military campaigns that enveloped the region, the daily disintegration of slavery in the countryside, and political developments across the four states and in Washington DC, John C. Rodrigue identifies the Lower Mississippi Valley as the epicenter of emancipation in the South. A sweeping examination of one of the war's most important theaters, this book highlights the integral role this region played in transforming United States history.

Sediment cores with new radiocarbon dates from the southern outlet of glacial Lake Agassiz indicate that meltwater delivery to the Mississippi valley was disrupted at 10,800 14C yr B.P. and the outlet was abandoned by 9400 14C yr B.P. These findings confirm the timing of generally accepted terminations of the Lockhart and Emerson Phases of Lake Agassiz. Additionally, the radiocarbon chronology indicates that the spillway was fully formed by 10,800 14C yr B.P. and that the occupancy in late-Emerson time was likely short-lived with minimal spillway erosion.
