A redoubt is a type of fortification, typically a small, temporary defensive structure. It is designed to protect soldiers and equipment from enemy fire and can be built quickly in response to a threat. Redoubts often feature earthworks, such as mounds of dirt, and may include wooden or stone walls to enhance their defensive capabilities. Historically, redoubts have been used in various military conflicts, including the American Revolutionary War and the Napoleonic Wars. They serve as strategic points for holding ground and can be part of a larger defensive system, working alongside other fortifications like bastions and trenches.
