Also the Charleston authorities did not even try to occupy the United States Arsenal, in Charleston itself, until it was surrendered. They simply posted sentries around the facility and would not let anyone in or out without a reason. That was the Charleston Arsenal commanders complaint in his reports, made many days after Anderson had occupied Fort Sumter, was that they were being held in the arsenal. That does not sound like an overtly aggressive mob scene, with pitchforks, tar, feathers, boiling oil and clubs beating down the doors of the Arsenal.
So what was Anderson afraid of from the citizens of Charleston while he was setting in a Fort surrounded by a moat and the ocean, with the approached covered by howitzers and loopholes for the riflemen? I wonder how many of our embassy guard forces have ever felt threaten by the local populas in some of the countries that aren't too friendly to the United States? I wonder what Anderson would have done, for example, had he been in command of the American Embassy Marine Guard force in Iran in 1978?
