16. In the summer of 1799, four thousand six hundred men, led by Generals Sullivan and James Clinton, were sent against the Indians on the Susquehanna. At Elmira the savages and tories had fortified themselves; but on the 29th of August they were forced from their stronghold and utterly routed. The country between the Susquehanna and the Genesee was wasted by the patriots. Forty Indian villages were destroyed. [Sidenote: =Campaigns in the South.=] 17. A little later, the tories, who were advancing to join the British at Augusta, were defeated by the patriots under Captain Anderson. On the 14th of February they were again overtaken and routed by Colonel Pickens. Colonel Boyd, the tory leader, and seventy of his men were killed. Seventy-five others were captured, and five of the ringleaders hanged. The western half of Georgia was quickly recovered by the patriots. 18. General Ashe was sent with two thousand men to intercept the enemy. On the 25th of February the Americans crossed the Savannah, and pursued Campbell as far as Brier Creek. Here the patriots came to a halt; and General Prevost, marching from Savannah, surrounded Ashe's command. A battle was fought on the 3d of March; the Americans were totally routed and driven into the swamps. By this defeat Georgia was again prostrated, and a royal government was established over the State. 19. Within a month General Lincoln was again in the field with five thousand men. He advanced up the left bank of the river in the direction of Augusta; but, at the same time, General Prevost, now commanding the British forces in the South, crossed the Savannah and marched against Charleston. General Lincoln turned back to attack him, and the British made a hasty retreat. The Americans overtook the enemy at Stone Ferry, ten miles west of Charleston, but were repulsed with considerable loss. Prevost then fell back to Savannah. [Sidenote: =Attempts to retake Savannah.=] 20. In September, Count d'Estaing arrived before Savannah with his fleet. Prevost concentrated his forces for the defence of the city. The French effected a landing, and advanced to the siege. D'Estaing demanded a surrender; but Prevost answered with a message of defiance. The siege was pressed with vigor, and the city constantly bombarded. But the defences remained unshaken. At last D'Estaing notified Lincoln that the city must be stormed. Before sunrise on the 9th of October the allies advanced with great vehemence against the redoubts of the British, but were driven back with fearful losses. Count Pulaski was struck with a grape-shot, and was borne dying from the field. D'Estaing retired on board the fleet, and Lincoln retreated to Charleston.
