The loss of the forts had demonstrated the power of the Federal fleet, and the impossibility of defending the island coast with the guns which the State and the Confederacy could furnish. The 32 and 42 pounders were no match for the 11-inch batteries of the fleet, and gunboats of light draught, carrying such heavy guns, could enter the numerous rivers and creeks and cut off forts or batteries at exposed points, while larger vessels attacked them, as at Port Royal, in front. It was evident that the rich islands of the coast were at the mercy of the Federal fleet, whose numerous gunboats and armed steamers, unopposed by forts or batteries, could cover the landing of troops at any point or on any island selected.
On the capture of Port Royal, it was uncertain, of course, what General Sherman's plans would be, or what force he had with which to move on the railroad between Charleston and Savannah. The fleet was ample for all aggressive purposes along the coast, but it was not known at the time that the army numbered less than 15,000 men, all told. But it was well known how easily a landing could be effected within a few miles of the railroad bridges crossing the three upper branches of the Broad river, the Coosawhatchie, Tulifinny and Pocotaligo, and the rivers nearer to Charleston, the Combahee, Ashepoo and Edisto. Bluffton, easily reached by gunboats, afforded a good landing and base for operations against the railroad at Hardeeville, only 4 miles from the Savannah river, and 15 from the city of Savannah. On this account, General Ripley, assisted by the planters,
