But I assume you are referring to Mr. Doubleday's account of the crossing from Moultrieville to Ft. Sumter.
Don't you find it fascinating that Anderson was successful in moving his entire command, as well as supplies, wives, trunks, boxes, etc., out of Ft. Moultrie during the late afternoon, through the entire town, down to the docks to three schooners and a series of rowboats? And then sailing and rowing over to Ft. Sumter and Johnson.
All of this involved passing Confederate soldiers stationed on the island and sentry ships in the harbor.
What sleight of hand!
What Doubleday says is that their entire movement drew no fire which proves the point that Anderson was not threatened, and had no reason remove himself, thus completely disobeying the intent of the War Department and becoming President-elect Lincoln's political and military focal point.
It doesn't prove anything of the sort.
