The Anaconda Plan as a continental siege

Where did General Winfield Scott's Anaconda Plan come from?

It was classic Vauban-style siege warfare applied to the Confederacy, with blockade and advancing forces serving as enclosing and contracting lines.

Scott and his contemporaries were trained in artillery and military engineering, so the plan's logic did not require a uniquely naval invention. An outer line keeps outside support away, an inner line contains the Confederacy, and parallel advances compress the defended space. The comparison makes the blockade part of a combined land-water siege system.
