As a surgeon, Thomas Hewson Bache provides an on-the-ground view of the Civil War in a diary, maintained throughout 1862 (1/1-11/28), that traverses the American North and South. The first half of the journal documents his life at camps in the South, including Baton Rouge, Cape Hatteras, New Orleans, and Vicksburg, and, starting in late-September, he returns to the northeast, first to New York and then to Philadelphia. In addition to providing a glimpse at soldier camps—especially in Baton Rouge (8/8)—Bache records at least one instance of Yellow Fever. Read together with the Alexander Dallas Bache diary, also from 1862, this volume furnishes researchers with new insights into the Civil War as it was experienced by those on its battlefields.
