What did Robert E. Lee do at fort Pulaski?

Robert E. Lee played a significant role in the construction of Fort Pulaski during the 1830s, serving as a topographical engineer. His work involved surveying the site and overseeing the fort's design and construction, which was part of a larger effort to strengthen coastal defenses in the United States. Although Lee is best known for his leadership of Confederate forces during the Civil War, his early military career included important engineering projects like Fort Pulaski. The fort later became a critical site in the Civil War, but Lee was not directly involved in its military actions during that time.
