This book is perfect.
Jarrow, whose Fatal Fever: Tracking Down Typhoid Mary, Red Madness: How a Medical Mystery Changed What We Eat, Bubonic Panic: When Plague Invaded America and The Poison Eaters all show impressive writing on medical topics, narrows on what is to me the most fascinating fact about the Civil War: sickness claimed more lives than violence. Diarrhea was one of the most common killers. Nothing takes the glory away from dying for one's country more than a discussion of the number of diseases that could cause this outcome.
This is serious business. The Civil War affected so many families, and in addition to the fatalities among soldiers, there were men who came back in extremely poor health due to a huge number of causes. Jarrow used military records to try to break down the administration of health services, the statistics about various diseases, and to highlight individuals who died because of the war. She does mention that there are far more extant records of the Union forces, but that ratios are probably similar in the Confederate cases.
This book is nicely organized, and well designed, with plentiful period photographs and illustrations. Famous figures, such as Clara Barton, are highlighted, but there are lesser known luminaries, like Mary Livermore, who fought for more sanitary conditions in military hospitals, as well. The end notes are very complete, there is a really informative timeline, and the glossary of terms is helpful as well.
Readers who want heroic tales of combat might be disappointed in this, but the cover will draw them in, and they will read at least half of the book before they realize that they are deep into a discussion about scurvy. Students who want to research the Civil War for a history project will find this an invaluable resource about innovations in medicine, technology, and practices that came out of this time period. This is an essential book for middle school and high schools, especially when the Civil War is part of the curriculum.
