"War is 99 parts diarrhea and one part glory." Walt Whitman had a point when he wrote this. Diseases like dysentery, typhus, and malaria were responsible for 2/3 of the deaths in the Civil War.

So, how did illness kill more soldiers on the battlefield than cannons and bayonets? It helps to look at the living conditions and atrocious medical practices in field hospitals during the deadliest war in American history. And it didn't help that sexually transmitted diseases like syphilis were rampant among soldiers.
