But of course you do?
Although the term "proceed" was used in several accounts, the definition of proceed was never given....proceed back out?...proceed to the bar to anchor?...proceed to Savannah?
How about 'proceed on her original course?' The Nashville was bound for Charleston. The Lane allowed her to proceed on that course once she identified herself. She did not turn the Nashville back to sea. She did order her to remain with the resupply ships. She did not order her to proceed to another port. She allowed the Nashville to continue in the direction she was originally heading. That does not sound like a blockade to me.
What you do know is that the Nashville stopped........plain and simple. It was stopped from continuing its regular run into Charleston Harbor. That fact, along with the fact that another schooner was seized, constitutes a blockade, and was the first act of war.
Complete nonsense.
