The civil war had even more prostitutes. The word Hooker comes from General Hooker. The General was known for having the women near the camp so he could manage his men. Hookers were on both sides in large numbers. America drank, paid for sex and gambled to access for most of its history.
Yes, after I got my DNA tested, a woman contacted me and asked if I had any relatives who served in Virginia in the Civil War. I said: “Yes, my grandfather.” (He enlisted at age 16.) It turns out that we’re cousins, and she might be my grandfather’s grandaughter or great- or something.
Not true (etymologically anyway)....
“hooker” as prostitute dates to 1845, if not before.
