History
The forest provided the region's major industries through the 18th and most of the 19th century: naval stores and lumber fueled the economy both before and after the American Revolution. During the Revolutionary War, the British maintained a garrison at Fort Johnson near Wilmington. After suffering crippling losses at Guilford Court House, the British withdrew all forces back to Fort Johnson and abandoned plans to occupy North Carolina. This prompted the British to attack Yorktown, Virginia instead, which brought an end to the war.
The town took its name from the large house of Captain Roger Haynes.
Leading up to the 2011 election, there was a large movement among the residents to incorporate Castle Hayne to become the "Town of Castle Hayne". Nearby Wilmington had previously forced an annexation of Monkey Junction in 2010 and proposed a forced annexation of Ogden, both of which had resulted in numerous lawsuits and appeals.
The incorporation referendum failed in November 2011.
