This was after the Union capture of Port Royal Sound.
From the November 16, 1861, New York Times.
"We have late and important intelligence from Port Royal by an arrival at this port and from Charleston papers of the 12th inst., received in Baltimore by way of Old Point. The transport steamer Coatzacoalcos arrived here yesterday morning, having left Port Royal the afternoon of Wednesday.
"Our troops at that time, had all landed, and their stores and ordnance were being rapidly discharged. There was a rumor that our pickets near the Savannah Ferry had been attacked by the rebels, and reinforcements were sent on the day the Coatzacoalcos left."
