This cartoon map illustrates Gen. Winfield Scott's plan to crush the Confederacy, economically, during the Civil War. It is sometimes called the "Anaconda Plan." This map somewhat humorously depicts Winfield Scott’s “Anaconda Plan” which resulted in an overall blockade (beginning in 1862) of southern ports and not only targeted the major points of entry for slave/slave trade but also crippled cotton exports.
