I have visited re-enactment field hospitals for both the American revolution (Yorktown) and the Civil war (Ghettysburg).
By all accounts the Revolution, 85 years earlier, had better battlefield care.
Go Figure!
Ooops..misspelled Gettysburg! Sorry.
A feisty lady from NC, known as Aunt Abby, tried to improve conditions in Confederate hospitals.
I read a magazine article about her a few years ago. President Davis and General Lee dreaded her visits, but the men she nursed adored her.
Her fiancé had died during the War of 1812 and from that memory she wanted the soldiers fighting for the Confederacy to have better care.
