>>> Thursday night on Columbus Neighborhoods, we explore a few of Ohio's connections to the American Civil War. >>> What is a battle flag and what was it used for in the Civil War? >>> Each regiment in the Civil War would carry a battle flag. They would have normally two flags, a national flag, and they also would carry a regimental flag, which would highlight their specific regiment. There were about 200 regiments from Ohio. >>> Thursday night at 8:30 on WOSU TV.
