Very few redoubts survive, including Briconet, Ximenes and St. George Redoubts. These geographic features were strengthened by a series of entrenchments, fortifications and redoubts. Fortress Rosecrans consisted of eight lunettes, four redoubts and connecting fortifications. A network of batteries, breastworks, redoubts and rifle pits defended the town. This comprised a strong earthen rampart, enhanced with bastions and redoubts. During the American Revolution, the area was the location of numerous fortifications, redoubts and breastworks. The perimeter included many gun pits, forts, trenches, redoubts, and lunettes. The attack captured the Confederate redoubts, their artillery and the majority of their garrisons. Damas put nine battalions in the first line defending three artillery redoubts. They were confronted by some of the strongest Ottoman defences, dominated by four redoubts. In Dresden, French infantry manned the various redoubts and defensive positions. The third line was a series of small redoubts for two or four platoons. Attacks intended as feints against other redoubts of the British position were easily taken. These two redoubts were key to breaking the British defenses. In all, eleven pentagonal redoubts and a few semi-circular or rectangular ones were built.
