The last blockade runner to make Savannah was the British steam ship "Fingal". Its cargo of arms and munitions reached the entrance to Wassaw Sound at the mouth of the Savannah River on a clear night in mid November, but heavy fog in the early morning masked the ship's progress across the bar and upriver. Later she made two unsuccessful attempts at escaping the blockade before being converted into an ironclad. Pulaski's share on ship's manifest was two 24-pounder Blakely rifles and a large consignment of British-made Enfield infantry rifles. As the Union Flag Officer Du Pont sought to close the alternative channels local ships used, he sank stone-filled ships in the Savannah River channel, and stationed gunboats at two southerly estuaries, Wassaw Sound, south of Wilmington Island, and Ossabaw Sound at Skidaway Island.
