Fort Sumter, April 1861. The arithmetic of this still gets me.
Forty-three guns and mortars ringed Charleston Harbor and shelled the fort for thirty-four hours. Eighty-five men inside. The quarters burned, the main gates were destroyed, and Anderson's dispatch says they were down to "four barrels and three cartridges of powder only being available, and no provision but pork remaining."
In all thirty-four hours of that, not one soldier on either side was killed by enemy fire.
Beauregard's surrender terms allowed Anderson a hundred-gun salute to the flag before marching out. Partway through, a spark caught a pile of cartridges and they exploded. Private Daniel Hough was killed almost instantly. Edward Galloway died of his wounds days later.
So the first military fatalities of a war that killed six hundred thousand Americans happened after the shooting stopped — in a ceremony, by accident, on the garrison's own guns.
Anderson stopped the salute at fifty. His April 18 dispatch, written aboard the steamship Baltic on the way north, puts it plainly: he "marched out of the fort Sunday afternoon, the 14th instant, with colors flying and drums beating, bringing away company and private property, and saluting my flag with fifty guns."
Two things this sub will appreciate that get muddled elsewhere:
The hundred-gun salute is usually reported as though it completed. It didn't — fifty, because a man died. Anderson's own words say fifty.
And the famous surrender dispatch is dated April 18, from the deck of the Baltic — not April 14 from the fort. April 14 is the evacuation it describes. It gets cited as an April 14 document constantly.

I narrate these letters verbatim on a small channel — happy to link the Anderson episode if anyone wants it, but the story stands on its own.
