"The United States Arsenal in Charleston is situated on the banks of the Ashley River. It looked feasible to go there in a boat without attracting attention, and procure a full supply of cartridges and other articles which were very much needed. Captain Seymour volunteered for the service, and was sent over with a small party, early in the afternoon. Notwithstanding he took every precaution, some spy belonging to a vigilance committee followed him, and reported the facts in the city. Seymour at once found himself beset by an excited mob, and wholly prevented from accomplishing the object of his mission. Colonel Gardner wrote to Mayor Macbeth for an explanation. The latter apologized politely for this unexpected occurrence, and, speaking for himself and other city officials, stated that so long as they staid in the Union they desired to remain faithful to its obligations, and that no further obstacles would be thrown in the way of another expedition. Colonel Gardner, however, did not send out again, thinking, perhaps, the mob might be beyond the control of the mayor." Doubleday
Very different than Humphreys and even Porter's Report.
