At Charleston, S. C., General Beauregard issued the following proclamation: “It has become my solemn duty to inform the authorities and citizens of Charleston and Savannah that the movements of the enemy's fleet indicate an early land and naval attack on one or both cities, and to urge that persons unable to take an active part in the struggle shall retire. It is hoped, however, that this temporary separation of some of you from your homes will be made without alarm or undue haste, thus showing that the only feeling which animates you in this hour of supreme trial is the right of being able to participate in the defence of your homes, your altars, and the graves of your kindred. Carolinians and Georgians! the hour is at hand to prove your country's cause. Let all able-bodied men from the sea-board to the mountains rush to arms. Be not too exacting in the choice of weapons. Pikes and scythes will do for exterminating your enemies, spades and shovels for protecting your firesides. To arms, fellow-citizens! Come to share with us our danger, our brilliant success, or our glorious death.” --About noon to-day ten wagons sent out on a foraging expedition from Memphis, were attacked and captured in Nonconnah Bottom, by a party of one hundred and fifty rebel cavalry.
