From this point on the island, turning our faces northward, with Morris Island northwest of us, and looking directly north out into the channel, we saw a number of Union gun boats, like a flock of black sheep feeding on a plain of grass; while the men pacing their decks looked like faithful shepherds watching the flock. While we negroes remained upon Sullivan's Island, we watched every movement of the Union fleet, with hearts of joy to think that they were a part of the means by which the liberty of four and one-half millions of slaves was to be effected in accordance with the emancipation proclamation made the January preceding. We kept such close watch upon them that some one among us, whether it was night or day, would be sure to see the discharge of a shot from the gun boat before the sound of the report was heard. During that summer there was no engagement between the Union fleet and the Confederates at that point in South Carolina. The Union gun boats, however, fired occasional shots over us, six miles, into the city of Charleston. They also fired a few shells into a marsh between Sullivan's Island and Mount Pleasant, but with no damage to us. WHAT WORK THE NEGROES DID ON THE ISLAND. After we had reached the island, our company was divided. One part was quartered at one end of the Island, around Fort Moultrie, and we were quartered at the other end, at Fort Marshall. Our work was to repair forts, build batteries, mount guns, and arrange them. While the men were engaged at such work, the boys of my age, namely, thirteen, and some older, waited on officers and carried water for the men at work, and in general acted as messengers between different points on the island. ENGAGEMENT ON LONG ISLAND. Though there was no fighting on Sullivan's Island during my stay there, Confederate soldiers at times crossed the inlet from Sullivan's to Long Island, in the night and engaged in skirmishes with Union soldiers, who had entered the upper end of that island and camped there. Whether these Confederate scouts were ever successful in routing the Union forces on the island or not I have never learned, but I know that they were several times repulsed with considerable loss. NEGROES ESCAPE. The way the Confederates came to the knowledge that Union soldiers were on Long Island was that the group of negroes who preceded us on Sullivan's Island had found out that Union soldiers were camping on the upper end of Long Island. So one night quite a number of them escaped by swimming across the inlet that divides Sullivan's Island and Long Island, and succeeded in reaching the Union line.
