How did the brits feel about the south? What was their plan/ reason to concentrate troops there?

The Continental victory at Saratoga in 1777 and the Treaty with the French in 1778 transformed the war, especially for the British. Increased French aid to the Continentals was very slow in coming; coordinated military activity between the two new allies was even slower to happen. Meanwhile, the British were immediately faced with a global conflict with France. As a result, the British changed their strategy yet again in 1778. Rather than mounting a full-scale military campaign against the Continental Army, the British decided to focus their efforts on the loyalists, who they still believed were the majority of the American population.

Good luck : )
