The picture most people carry of Civil War surgery is a tent, a screaming man with a bullet between his teeth, and a heap of limbs outside the flap. Two of those three details are broadly right. The bullet is not.
I spent a long time inside this material before writing Bone Saw, and what surprised me was not how brutal the period was. It was how much of the brutality was competent.
They had anaesthesia, and they used it
Ether had been demonstrated publicly in Boston in 1846 and chloroform followed within a year. By 1861 both were ordinary. The surviving Federal medical records describe tens of thousands of administrations, and anaesthesia was the rule rather than the exception in operative cases on both sides.
The choice between the two agents was practical rather than philosophical. Chloroform is more potent, needs less of itself, and does not catch fire near a lamp, which matters in a tent. Ether is safer for the heart and harder to kill a man with, and it travels badly. In the novel that difference has a geography. Chloroform is the Confederate agent and later the frontier agent. Ether belongs to Chicago, where a surgeon can rely on a freight schedule. When Ballard goes west he sells the ether, because no supply line beyond Omaha would keep him in it.
The bitten bullet has some basis in fact, though. Supply failed. Trains were late, depots were captured, and a battle produced casualties faster than anybody had planned for. There is a scene in Bone Saw where the ether runs out on the Monday of the Chicago fire, and a drayman’s amputation proceeds on whiskey and three men holding him down. That is what the absence looked like, and the point is that it was an absence rather than a practice.
The amputations were usually correct
A soft lead ball travelling slowly does not drill a neat hole. It flattens, tumbles, and drives cloth and dirt ahead of it, and when it meets the shaft of a femur it does not crack the bone so much as burst it along several inches. There was no repairing that in 1864. There was no vascular surgery, no transfusion worth the name, no antibiotic, and no reliable way to stop the infection that a shattered limb full of fabric was going to produce.
The period had its own vocabulary for the decision. A primary amputation was one performed early, within the first day or so. A secondary amputation came later, usually after infection had already declared itself. Primary amputation had markedly better survival, and surgeons knew it, which is why the speed that looks like callousness in the popular image was in fact the thing most likely to save the patient.
Trying to save the limb had a name too. Conservative surgery, meaning conserving the leg rather than conserving the man. It was sometimes right and sometimes a slower way of arriving at the same operation with a worse patient. In the novel a father refuses the amputation and takes his son home from a gravel pit. The father is wrong and the son dies, and the narration does not punish him for it, because the decision was not an obviously foolish one at the time.
What they genuinely did not know
Here the myth has a point, but it is aimed at the wrong thing. The failure was not the cutting. It was everything around the cutting.
Lister did not publish on antisepsis until 1867, and American practice did not take it up in any general way until well into the following decade. Surgical gloves arrived later still, around 1889 or 1890, out of Halsted’s clinic. In 1864 a surgeon wiped his hands on his apron between cases because there was nothing in his training to tell him otherwise, and hospital gangrene moved through the wards accordingly.
So the men who cut well and fast, and who had good reasons for every decision they made, were also carrying the thing that killed their patients from one bed to the next on their own hands. That is a more disturbing arrangement than incompetence, and it is the one the historical record actually supports.
The column nobody kept
There is a passage late in Bone Saw that I think of as its argument. Ballard, by then an established Chicago physician, compiles his operative results for the county medical society in 1879 and finds his mortality better than two rival practices and better than the hospital’s published rate. There is no trick in the figures. He did not select his cases or quietly lose men out of the record. He operated early, and men operated on early died less often. He checks his addition twice and it is sound.
What the return has no column for is what the men did afterward. Whether they worked. Whether anyone married them. What the arm cost them across thirty years. No such return in the country carried a column like that, because a profession measures what it can measure, and the dead can be counted.
Ballard is not a butcher. He is better than the men around him and he can prove it. The proof is in the language of the institution and it is entirely valid, and it still misses the whole of what happened to the people in it. That gap is where the novel lives, and it is why the saw itself never needed to be haunted.
Bone Saw releases on 6 October 2026. The Prelude is here, and it is about the man who made the instrument rather than anyone who used it.
