How Fort Fisher Came to Be in Pleasure Island (and Federal and Confederate Point)

From the October 3, 2021, Wilmington (North Carolina) Star-News "What's the story behind the 'Pleasure Island' name?"

Anyone visiting Fort Fisher might see it advertised as being on Pleasure Island or Federal Point.

QUESTION:  When and how did Pleasure Island get its name?  I assume it was just called Federal Point then.

ANSWER:   Rebecca Taylor, manager of the Federal Point History Center explains it this way.

 James Sprunt, long-time historian of the lower Cape Fear River area, says Federal Point was named  in honor of the new Federal Constitution adopted in 1788.  During the Civil War, the name obviously was changed to Confederate Point after North Carolina seceded from the United States.  The name was changed back to Federal Point after the war.

But, what does that have to do with Pleasure Island as a name for the area?
