A Local Civil War Fact mentioned on TV

So I was watching "Only in America" with Larry the Cable Guy (I don't know why either, so don't ask) and they had a segment on squirrel hunting and said (I'm paraphrasing): "During the Civil War, the Confederates did not invade Ohio because they enlisted 15,000 squirrel hunters" before making some joke about the squirrels being happy about that.

I found it interesting that such a fairly obscure Civil War fact was mentioned in a show like that. I guess his writers may be Civil War buffs or maybe there just are not many interesting facts about squirrels and squirrel hunters out there.

Also, that is an actual bit of history mentioned on the History Channel (or "History" as it is now known.) That seems unusual too (Perhaps there were no "ancient alien squirrel hunters" they could discuss.)
