I have another Civil War question. How did the war split families and divide friends? My answer--

It pitted brother against brother, parents against their children, and neighbor against neighbor. For example, John Crittenden had two sons who were generals in the war - one for the Confederacy and one for the Union.

Do you think this is too long or what my teacher might be looking for??

It's not too long, and I think it's what your teacher expects. Families and friends lived on both sides. It wasn't unusual for brothers and cousins to fight on opposite sides.

Your answer provides a good explanation of how the Civil War split families and divided friends. It highlights the conflict between individuals who were on opposite sides of the war, even within the same family. However, if you are looking to make your answer more concise, here's a shorter version:

"The Civil War created deep divisions within families and friendships. It resulted in brothers fighting against each other, parents in disagreement with their children, and neighbors becoming enemies due to their allegiances to the Union or Confederacy."
