The South was a goldmine to whichever side could hold it. Southern commodities like tobacco, rice, indigo, and pine tree products made the South the richest area of the country.
Furthermore, the British felt that they had much stronger support from the Loyalists in the South than in the North. They didn't reckon on the strong Patriot contingent in the South as well.
As it turned out, the people of the Southern states were so deeply divided between Patriots and Loyalists that some of the hardest and bloodiest fighting of the war would occur there.
But meanwhile, General Henry Clinton and Admiral Parker initially headed for Cape Fear, NC to establish a port of entry for the British. This did not work out so the next stop was Charleston. Earlier reconnaissance had shown that the fortifications around Charleston were incomplete, making it an easy target - or so the British thought.
