New weapons, old medicine
From Simon Winchester’s The Professor and the Madman:
Here was an inescapable irony of the Civil War, not known in any conflict between men before or since: the fact that this was a war fought with new and highly effective weapons, machines for the mowing down of men—and yet at a time when an era of poor and primitive medicine was just coming to an end. It was fought with the mortar and the musket and the minié ball, but not yet quite with anesthesia or with sulphonamides and penicillin. The common soldier was thus in a poorer position than at any time before: he could be monstrously ill-treated by all the new weaponry, and yet only moderately well-treated with all the old medicine.
