What areas in the american colonies suffered the most during colonial wars?

-...The City of New York fared particularly bad during the Revolutionary War. After the British victory at the Battle of Long Island in 1776, the British occupied the city and did not relinquish it until the peace was signed in 1783. During that time, it was a headquarters for the British. The occupiers did not purposely destroy the city, however, the combination of actions on the part of patriots (setting fire to the city to lessen its value to the occupiers), along with the constant requisitioning of supplies and housing by the British, brought devastation to the city which was, before the war, the third largest port in the British Empire. Commercial port facilities fell into disuse and the infrastructure of the city was not maintained.



The city, due to its use as a British headquarters (and because of its geography, was virtually invulnerable to an American attack, in particularly because the Americans did not have a decent navy), became a focal point for Tory activity. When the British finally did evacuate, many Tories (and freed slaves) left the city, taking with them their wealth. By the end, the city was a shell of what it once was.
I am not aware of any areas that were subjected to reprisals or deprivations. It is well to remember that there were many colonists who remained loyal to the British Crown in all areas of the colonies. Most of these people did not go to Canada or the West Indies until after the war. For this reason the British Army would not have punished civilian populations.
New Jersey saw a number of battles but I would suggest South Carolina. Though much of the war was fought in the north the partisan conflict in this colony was awful. Leaders from both sides, including Nathanael Greene and Lord Rawdon commented on the ferocity with which both rebels and loyalists attacked each other. Many of the battles were small and did not involve army regulars, but it was not uncommon for small bands of men to seek their own style of justice on members of the opposition. Men like Francis Marion. Sumter and Pickens, were able to get large numbers to turn out to fight with them in an instant due to the constant threat of violence especially in the years 178-1782.
