What made Sir Henry Clinton focus on the south in his battle strategies?please help w/ this history question.

What Great Britain could get from the South that it could not from the North was raw materials for its burgeoning industry.  In fact, the Northern states were competing (although on a small scale) with industrial Britain as they themselves began to industrialize. Culturally, the South had the stronger tie to Britain since the early Southern colonists were from the English gentry or from Scotland or Ireland; the population was much more homogeneous than in the North, where colonists came from all over.

As far as Britain was concerned, the Northern colonies were all settled by religious extremists with whom the British elite had nothing in common (they are in fact, one of the many reasons religious differences forced many to flee to the New World.) By the time Henry Clinton (1738-1795) began his Southern invasion in 1779, Northern battles had already yielded only questionable British victories, and he decided to try his luck elsewhere.  Unfortunately, the same guerrilla tactics that were successful in the North were successful in the South as well, even though the British had captured the major cities.
