A redoubt (historically redout)
is a
fort or fort system usually consisting of an enclosed defensive emplacement outside a larger fort, usually relying on
earthworks
Earthworks may refer to:
Construction
*Earthworks (archaeology), human-made constructions that modify the land contour
* Earthworks (engineering), civil engineering works created by moving or processing quantities of soil

, although some are constructed of stone or brick. It is meant to protect soldiers outside the main defensive line and can be a permanent structure or a hastily constructed temporary fortification. The word means "a place of retreat".
Redoubts were a component of the military strategies of most European empires during the colonial era, especially in the outer works of
Vauban-style fortresses made popular during the 17th century, although the concept of redoubts has existed since
medieval times. A redoubt differs from a
redan in that the redan is open in the rear, whereas the redoubt was considered an enclosed work.
The advent of
mobile warfare in the 20th century diminished the importance of stationary defence positions and
siege warfare.
Historically important redoubts
English Civil War
During the
English Civil War redoubts were frequently built to protect older fortifications from the more effective artillery of the period. Often close to ancient fortifications there were small hills that overlooked the defences, but in previous centuries these had been too far from the fortifications to be a threat. A small hill close to Worcester was used as an artillery platform by the
Parliamentarians when they successfully
besieged Worcester in 1646. In 1651 before the
Battle of Worcester the hill was turned into a redoubt by the
Royalists, (the remains of which can be seen today in
Fort Royal Hill Park). During the
Battle of Worcester, the Parliamentarians did capture this redoubt and turned its guns on Worcester. In so doing they made the defence of the city untenable. This action effectively ended the battle, the last of the
English Civil War.
Malta
From 1715 onwards, the
Order of Saint John built a number of redoubts in
Malta, as part of an effort to improve the
coastal fortifications of the islands. They were built in the middle of bays to prevent enemy forces from disembarking and outflanking the
coastal batteries

.
The design of the redoubts was influenced by ones built in the French colonies. In all, eleven pentagonal redoubts and a few semi-circular or rectangular ones were built. Most redoubts have been demolished over the years, but a few still survive, such as
Briconet Redoubt,
Saint George Redoubt and
Ximenes Redoubt.
Four ''tour-reduits'' were also built. These were redoubts built in the form of a tower, with rows of musketry loopholes. Three were around
Marsaxlokk Bay, and one was located in
Marsalforn,
Gozo

Vendôme Tower in Marsaxlokk.
During the
siege of Malta of 1798–1800, Maltese insurgents built
a number of fortifications to bombard French positions and repel a possible counterattack. Most of the fortifications were batteries, but at least two redoubts,
Windmill Redoubt and
Żabbar Redoubt, were also built. In 1799, British forces also built
San Rocco Redoubt and
San Lucian Redoubt in Malta. No redoubts from the French blockade survive today.
In the late 19th century, the British built a redoubt near

The American Revolution defenses at
West Point, New York included several redoubts, forts, and the

with links weighing more than 100 pounds each that Continental Army military engineers stretched across the Hudson River. The purpose behind the West Point defensive system was to prevent the British Army and Royal Navy from gaining control of the Hudson and splitting New England off from the mid-Atlantic and southern states. The chain blocked the river, the forts were positioned to fire on ships attempting to approach the chain, and outlying redoubts were well placed to defend land routes into West Point.

National redoubt
A national redoubt is an area to which the remnant forces of a nation can be withdrawn if the main battle has been lost, or beforehand if defeat is considered inevitable. Typically a region is chosen with a geography favouring defence, such as a mountainous area or a peninsula, in order to function as a final hold-out to preserve national independence for the duration of the conflict.
