PT-109 by Jimmy Dean
Rush Manhattan Project
Maybe a little vague story-wise, but Kansas’ “Song for America.”
Tom Rush’s “Wasn’t That a Mighty Storm” (a memorable if inaccurate song about the Great Galveston hurricane of 1900), recorded by others before and since.
Ooo, good one. I’ll add:
Bastille Day (about … Bastille Day)
Red Sector A (written from the perspective of a Jewish concentration camp inmate)
You forgot Sunday, Bloody Sunday.
I’ll also Jucifer’s album, L’Autrichienne, a concept album about Marie Antoinette.
Speaking of whom, “Marie Antoinette” by Curved Air.
“Sub Rosa Subway” by Klaatu. Epic event in it’s own way: it commemorates Alfred Beach secretly digging a subway in Manhattan.
I thought that was the song supposedly played by the British at Yorktown, but it isn’t. This is, but it isn’t a rocker.
Does “The Devil Went Down To Georgia” make it in under any stretch of the rules?
Tenacious D - “Tribute” … But the song they sang that night didn’t sound anything like this song.
Boney M, “Rasputin”
Camel, “Harbour of Tears” (Irish leaving home and coming to America after the famine)(actually pretty much anything on that album qualifies, as does their album “Dust and Dreams”)
There are lots of “Battle of” songs. New Orleans, Hadrian’s Wall, Little Big Horn, Evermore 
and others by various artists.
Lot a’ help I am, huh?
History based, though they’re all instrumentals: Rick Wakeman’s “The Six Wives of Henry VIII.” Each song is Wakeman’s impression of one of the wives.
The Band - Acadian Driftwood.
From Wikipedia:
80 million Irish folk songs
Elvis Costello - Oliver’s Army - Oliver Cromwell
Flogging Molly - Oliver Boy (All Of Our Boys) - same
Monty Python - Oliver Cromwell - ditto
Frank Turner - English Curse - William II Rufus (2nd Norman English king) mainly
The Decemberists (even their name is a reference) - The Tain -
Red Sparowes - Every Red Heart Shines Toward the Red Sun (a whole album) - despite being instrumental the song titles are about part of the Great Leap Forward, where efforts to eradicate pests lead to millions of deaths
PJ Harvey - Let England Shake (album) - most are about WWI.
Also a lot if Sufjan Stevens, but it’s mostly just the song titles
Lots of black or viking metal about the Christianization of Scandanavia (they’re anti, for the record)
Also every Dethklok song - I saw it with my own eyes!
More folk than rock, but a great song: MacDonnell on the Heights by Stan Rogers. About a hero of Canadian nationalism, who helped beat us Americans at the Battle of Queenston Heights in the War of 1812.
Their name is, and some of their other songs are (not as many as a lot of people seem to think), but what is historic about The Tain?
Do you believe these songs describe actual historical events?
Shit, I meant to remove that. The lyrics really aren’t historical, so no, doesn’t strictly count. At face value, the title references Táin Bó Cúailnge.
Only caught the wink as I was about to type out some scorn. Phew.
