Day after day the siege of Ninety-Six went on, the Americans slowly approaching the fort by a series of works constructed under the superintendence of Kosciusko, and Cruger still holding out in expectations of reinforcements from Charleston, although not a single word of intelligence from Lord Rawdon had reached him since the investment of the post which he held with so much bravery and perseverance. On the 3d of June, the long-expected reinforcement from England reached Lord Rawdon, and on the 7th he started for the relief of Colonel Cruger with a portion of three Irish regiments, and was joined soon after by the South Carolina royalists, swelling his force to two thousand men. But all his efforts to transmit intelligence of his approach to the beleaguered garrison at Ninety-Six proved unavailing. His messengers were intercepted by Sumter and Marion, who held possession of the intermediate region. On the 11th of June, General Greene received intelligence from General Sumter of the approach of Rawdon. Directing Sumter to keep in front of the enemy, he reinforced him with all his cavalry under Lieutenant-Colonel Washington, and urged him to use every means in his power to delay the advancing British army, until he should be able to complete the investment of the fort at Ninety-Six, and compel it to surrender. Then with renewed diligence he pressed the siege, hoping to obtain a capitulation before Colonel Cruger should receive news of the approaching succour, and thus break up, with the exception of Charleston, the last rallying point of the enemy in South Carolina. But the commander of the fort was ever on the alert to make good his defences and to annoy and retard the besiegers in every possible way; and, though ignorant of the near approach of aid, he would listen to no overtures for a capitulation. One evening, while affairs retained this aspect, a countryman rode along the American lines, conversing familiarly with the officers and soldiers on duty. No particular notice was taken of this, as, from the beginning of the siege, the friends of our cause were permitted to enter the camp and go wherever their curiosity happened to lead them. The individual here mentioned moved along, seemingly much interested with all he saw and heard, until he arrived at the great road leading directly to the town, in which quarter were only some batteries thrown up for the protection of the guards. Pausing here for a few moments, he glanced cautiously around him, and then, suddenly putting spurs to his horse, he dashed at full speed into the town. Seeing this, the guard and sentinels opened their fire upon him, but he escaped unhurt, holding up a letter as soon as he was out of danger. The garrison, which had observed this movement, understood its meaning, and the gates were instantly thrown open to receive the messenger, who proved to be from Lord Rawdon, and brought the welcome intelligence of his near approach.
