On December 1, 1863, Smalls was piloting the "Planter" under Captain James Nickerson on Folly Island Creek when Confederate batteries at Secessionville opened. Nickerson fled the pilot house for the coal-bunker. Smalls refused to surrender, fearing that the black crewmen would not be treated as prisoners of war and might be summarily killed. Smalls entered the pilothouse and took command of the boat and piloted it to safety. For this, he was reportedly promoted by Gillmore to the rank of captain and made acting captain of the "Planter".
