The beginning of incidents that would lead to the "Immortal 600".
HEADQUARTERS DEPARTMENT OF THE SOUTH,
Morris Island, S. C., August 21, 1863.
General G. T. BEAUREGARD,
Commanding Confederate Forces, Charleston, S. C.:
GENERAL : I have the honor to demand of you the immediate
evacuation of Morris Island and Fort Sumter by the Confederate
forces. The present condition of Fort Sumter and the rapid and progressive destruction which it is undergoing from my batteries, seem
to render its complete demolition within a few hours a matter of
certainty. All my heaviest guns have not yet opened.
Should you refuse compliance with this demand, or should I re-
ceive no reply thereto within four hours after it is delivered into the
hands of your subordinate at Fort Wagner for transmission, I shall
open fire on the city of Charleston from batteries already established
within easy and effective range of the heart of the city.
I am, general, very respectfully, your obedient servant,
Q. A. GILLMORE,
Brigadier-General, Commanding.
