The Surgeon's Battle: How Medicine Won the Vicksburg Campaign and Changed the Civil War

Civil War America

by Lindsay Rae Smith Privette

Between May 1 and May 22, 1863, Union soldiers marched nearly 200 miles through the hot, humid countryside to assault and capture the fortified city of Vicksburg, Mississippi. Upon its arrival, the army laid siege to the city for a grueling forty-seven days. Disease and combat casualties threatened to undermine the army’s fighting strength, leaving medical officers to grapple with the battlefield conditions necessary to sustain soldiers' bodies. Medical innovations were vital to the Union victory. When Vicksburg fell on July 4, triumph would have been fleeting if not for the US Army Medical Department and its personnel.

By centering soldiers' health and medical care in the Union army’s fight to take Vicksburg, Lindsay Rae Smith Privette offers a fresh perspective on the environmental threats, logistical challenges, and interpersonal conflicts that shaped the campaign and siege. In doing so, Privette shines new light on the development of the army’s medical systems as officers learned to adapt to their circumstances and prove themselves responsible stewards of soldiers' bodies.

Lindsay Rae Smith Privette’s The Surgeon’s Battle: How Medicine Won the Vicksburg Campaign and Changed the Civil War offers a captivating look at the decisive siege of Vicksburg.

Recounting the struggle for the city, Privette’s writing allows the reader to sympathize with the average Union infantryman, whose wartime experience included far more than dodging Confederate cannons. Drawing on an expansive knowledge of Civil War medicine, Privette shows how in times of siege and marching, mosquitoes and dysentery weighed just as heavily on doctors’ minds as enemy fire. Each chapter is rich with letters from the front lines, vividly portraying the awful conditions Grant’s men endured daily from May 18 to July 4, 1863.

The struggle between medical professionals, superstitious civilians, and bull-headed superiors is an especially compelling thread Privette explores, reminding us that Civil War history is much more than battlefields. Deftly weaving her research with primary sources and illustrations, The Surgeon’s Battle stands out as an important work for anyone seeking to understand how medicine not only sustained Union soldiers but also helped shape the outcome of the war itself.

Some awesome 19th century names in this. You got William Royal Oak, Alonzo Abernethy, Charlie Tripler, Seneca Thrall, Silas Trowbridge, and my two favorites, True Morrill and Ichabod Frisbie.

This was really cool. The author was able to explore medical history and provide extensive perspectives on soldiers' health / survival strategies, while still also giving an overall history of Vicksburg. Made for a very interesting and harrowing way to learn about a military campaign.

Interesting review of the performance of the Medical Department of the Army of the Tennessee. Climate, topography and mosquitos complicated care. Grant's plan to move quickly from the river to Jackson and back to Vicksburg resulted in the Army being separated from its supplies and hospitals. Foraging, previously forbidden or discouraged but now encouraged, enabled soldiers to supplement their rations and gave them an opportunity to help themselves. West of the river the land was low and marshy, not good for building temporary camps. East side was higher, easier to find dry ground. However, it was harder to find clean water.

This book read more like a dissertation but after I realized speed reading was not going to happen I cheered allll the words and found it interesting and educational. Just know it is NOT a thriller.
