Inscription.
A redoubt is a small temporary fortification of entrenched earth and wood. These battlefield strongpoints were designed to provide cover for defending infantry and artillery as well as slow down an attacking force. Several construction elements make up a redoubt. During the American Revolution both the British and Continental forces used John Muller's 1746 Elements of Fortification, which was a hybrid of the current theories of entrenchments put forth by Marshal de Vauban of France and the Baron Menno Van Coehorn of the Dutch Army. These systems emphasized a catalog of shapes and fortification features that a commander could fit to suit the particular circumstances of the battlespace. Before you is a recreation of an 18th century redoubt, can you spot the different design elements?

1. Embrasure: Opening in parapet for artillery to fire through.
2. Ships's carriage with 18 pdr cannon: Garrison carriages differ from ship's carriages by having small cast iron wheels as opposed to ones made of wood.
3. Gun platform: A floor made of joists and planks to serve as a foundation for artillery and mortars.
4. Fascine: Bundles of saplings bound with vines used to support the parapet.
5. 24 pdr mortar and bed: A short artillery piece mounted to a large wooden block

that fires projectiles at extreme elevations over the fortification.
6. Mortar pit: A gun platform specifically used for mortars.
7. Gabion: Basket shaped devices made of intertwined saplings and filled with earth and stone to support the parapet.
8. Parapet: Raised earthwork which serves as the cover for the defending troops.
