Then why not title your thread "Civil War letters come to New Ulm museum" and leave it at that?
Heck, using your style here, a post about the Battle of the Washoe House should be titled
"Drunken Whoring By Union Soldiers Prevents Their Punitive Raid On Peaceful City."
(actually, that is more accurate than your thread title, since your article is about the letters and briefly mentions the Indian raids as an aside, whereas the Battle of the Washoe House involved Union raiders going from Petaluma toward Santa Rosa to avenge the death of Lincoln, and stopping at the Washoe House - a roadhouse and tavern - for refreshments and other entertainment, then going home, being too tired to continue on their punitive raid)/
