Harbor chart · 1858
The Coast Survey chart of 1858
Preliminary chart of Charleston Harbor and its approaches
The harbor as the Confederacy inherited it, surveyed by the government that was about to be fired on. Most of the wartime harbor maps that follow are drawn from this survey, and the soundings and channels on them are these.
It is also the chart that explains the siege. The deep channel runs past Sumter and Moultrie, which is why the forts are where they are and why the Federal fleet spent two years trying to get past them.
