The confluence of developments in medical knowledge and military technology enabled doctors to learn a great deal about surgery during the American Civil War. Since, at the war’s outset, very few physicians had any experience treating gunshot wounds, P.J. Horwitz—a Jew from Baltimore and the Union navy’s surgeon general—authored a brief manual on the subject. Here are two excerpts:

Gunshot wounds include all injuries produced by firearms, and partake of the nature both of contused and lacerated wounds. The symptoms of a gunshot wound vary with the parts injured. When the wound is merely fleshy, and the mind of the individual wounded is not directed to the injury, the pain and inconvenience may be so inconsiderable as not to attract his notice, till his attention is called to his condition by the bystanders, or by some circumstances not connected with his injury. . . .

If on first seeing a patient who is wounded he is found to be much prostrated, the best thing to do is to try and soothe him by an encouraging manner, and assurances of his speedy recovery, and at the same to administer such stimulus as he requires, such as brandy and water, a little wine water and ammonia if necessary. Should he complain of much pain, a little laudanum would be serviceable; sometimes also an external warmth may be required.

While it is commendable that administrators of several universities finally called upon police to crack down on violent and disruptive anti-Israel protests, the actions they have taken may be insufficient. At Columbia, demonstrators reestablished their encampment on the main quad after it had been cleared by the police, and the university seems reluctant to use force again. The school also decided to hold classes remotely until the end of the semester. Such moves, whatever their merits, do nothing to fix the factors that allowed campuses to become hotbeds of pro-Hamas activism in the first place. The editors of National Review examine how things go to this point:

Since the 10/7 massacre, Columbia’s Jewish students have been forced to endure routine calls for their execution. It shouldn’t have taken the slaughter, rape, and brutalization of Israeli Jews to expose chants like “Globalize the intifada” and “Death to the Zionist state” as calls for violence, but the university refused to intervene on behalf of its besieged students. When an Israeli student was beaten with a stick outside Columbia’s library, it occasioned little soul-searching from faculty. Indeed, it served only as the impetus to establish an “Anti-Semitism Task Force,” which subsequently expressed “serious concerns” about the university’s commitment to enforcing its codes of conduct against anti-Semitic violators.

But little was done. Indeed, as late as last month the school served as host to speakers who praised the 10/7 attacks and even “hijacking airplanes” as “important tactics that the Palestinian resistance have engaged in.”

The school’s lackadaisical approach created a permission structure to menace and harass Jewish students, and that’s what happened. . . . Now is the time finally to do something about this kind of harassment and associated acts of trespass and disorder. Yale did the right thing when police cleared out an encampment [on Monday]. But Columbia remains a daily reminder of what happens when freaks and haters are allowed to impose their will on campus.
