PLEASE HELP How was the fighting in the South during the third stage of the war different than in the other stages of the war and regions of the colonies?

1. It was a mixture of bloody civil war between civilians, use of guerilla forces for hit-and-run attacks, and battles with standing armies

2. The British only used escaped slaves that they trained as soldiers to fight in the South

3. The fighting was done only with the large standing armies of the Continental army and the British army.

4. There was very little fighting done as the British only worked to occupy Charleston, South Carolina for its port so it could cut off trade for the southern colonies.

Can you please answer the question quick, please thank you
