Ravelin
A ravelin is a triangular fortification or detached outwork, located in front of the innerworks of a fortress (the curtain walls and bastions). Originally called a ''demi-lune'', after the ''lunette'', the ravelin is placed outside a castle and opposite a fortification curtain wall. The ravelin is the oldest and at the same time the most important outer work of the bastion fortification system. It originated from small forts that were supposed to cover the bridge that led across the moat to the city or fortress gate from a direct attack. From this original function, to protect the gate bridge, also comes its original Italian name "''rivellino''" (which means small bank work or with the German expression common for it: ''Brückenkopf'' – "bridge head"). Therefore, the ravelin was at first only a small work, which should only make the access to the bridge in front of the fortress gates more difficult. When it was realized in the 16th century that this would generally provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bastion Fort
A bastion fort or ''trace italienne'' (a phrase derived from non-standard French, literally meaning ''Italian outline'') is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield. It was first seen in the mid-fifteenth century in Italy. Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era. The design of the fort is normally a polygon with bastions at the corners of the walls. These outcroppings eliminated protected blind spots, called "dead zones", and allowed fire along the curtain from positions protected from direct fire. Many bastion forts also feature cavaliers, which are raised secondary structures based entirely inside the primary structure. Origins Their predecessors, medieval fortresses, were usually placed on high hills. From there, arrows were shot at the enemies. The enemies' hope was to either ram the gate or ...

Tilbury Fort
Tilbury Fort, also known historically as the Thermitage Bulwark and the West Tilbury Blockhouse, is an artillery fort on the north bank of the River Thames in England. The earliest version of the fort, comprising a small blockhouse with artillery covering the river, was constructed by King Henry VIII to protect London against attack from France as part of his Device programme. It was reinforced during the 1588 Spanish Armada invasion scare, after which it was reinforced with earthwork bastion, and Parliamentary forces used it to help secure the capital during the English Civil War of the 1640s. Following naval raids during the Anglo-Dutch Wars, the fort was enlarged by Sir Bernard de Gomme from 1670 onwards to form a star-shaped defensive work, with angular bastions, water-filled moats and two lines of guns facing onto the river. In addition to protecting the Thames, in the 18th century Tilbury also began to be used a transit depot and for storing gunpowder. It continue ...

Castillo De San Marcos
The Castillo de San Marcos ( Spanish for "St. Mark's Castle") is the oldest masonry fort in the continental United States; it is located on the western shore of Matanzas Bay in the city of St. Augustine, Florida. It was designed by the Spanish engineer Ignacio Daza, with construction beginning in 1672, 107 years after the city's founding by Spanish Admiral and conquistador Pedro Menéndez de Avilés, when Florida was part of the Spanish Empire. The fort's construction was ordered by Governor Francisco de la Guerra y de la Vega after a raid by the English privateer Robert Searles in 1668 that destroyed much of St. Augustine and damaged the existing wooden fort. Work proceeded under the administration of Guerra's successor, Manuel de Cendoya in 1671, and the first ''coquina'' stones were laid in 1672. The construction of the core of the current fortress was completed in 1695, though it would undergo many alterations and renovations over the centuries. Though built in part by ...

Sébastien Le Prestre De Vauban
Sébastien Le Prestre de Vauban, Seigneur de Vauban, later Marquis de Vauban (baptised 15 May 163330 March 1707), commonly referred to as ''Vauban'' (), was a French military engineer who worked under Louis XIV. He is generally considered the greatest engineer of his time, and one of the most important in European military history. His principles for fortifications were widely used for nearly 100 years, while aspects of his offensive tactics remained in use until the mid-twentieth century. He viewed civilian infrastructure as closely connected to military effectiveness and worked on many of France's major ports, as well as projects like the Canal de la Bruche, which remain in use today. He founded the , whose curriculum was based on his publications on engineering design, strategy and training. His economic tract, , used statistics in support of his arguments, making it a precursor of modern economics. Later destroyed by royal decree, it contained radical proposals for a mor ...

List Of Established Military Terms
This is a list of established military terms which have been in use for at least 50 years. Since technology and doctrine have changed over time, not all of them are in current use, or they may have been superseded by more modern terms. However, they are still in current use in articles about previous military periods. Some of them like ''camouflet'' have been adapted to describe modern versions of old techniques.

Fortification
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its ' cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, ...

Outwork
An outwork is a minor fortification built or established outside the principal fortification limits, detached or semidetached. Outworks such as ravelins, lunettes (demilunes), flèches and caponiers to shield bastions and fortification curtains from direct battery were developed in the 16th century. Later, the increasing scale of warfare and the greater resources available to the besieger accelerated this development, and systems of outworks grew increasingly elaborate and sprawling as a means of slowing the attacker's progress and making it more costly. When taken by an enemy force, their lack of rear-facing ramparts left them totally open to fire from the main works. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtain Wall (fortification)
A curtain wall is a defensive wall between two fortified towers or bastions of a castle, fortress, or town. Ancient fortifications Evidence for curtain walls or a series of walls surrounding a town or fortress can be found in the historical sources from Assyria and Egypt. Some notable examples are ancient Tel Lachish in Israel and Buhen in Egypt. Curtain walls were built across Europe during the Roman Empire; the early 5th century Theodosian Walls of Constantinople influenced the builders of medieval castles many centuries later. Curtain wall castles In medieval castles, the area surrounded by a curtain wall, with or without towers, is known as the bailey. The outermost walls with their integrated bastions and wall towers together make up the enceinte or main defensive line enclosing the site. In medieval designs of castle and town, the curtain walls were often built to a considerable height and were fronted by a ditch or moat to make assault difficult. Walls were t ...

Bastion
A bastion or bulwark is a structure projecting outward from the curtain wall of a fortification, most commonly angular in shape and positioned at the corners of the fort. The fully developed bastion consists of two faces and two flanks, with fire from the flanks being able to protect the curtain wall and the adjacent bastions. Compared with the medieval fortified towers they replaced, bastion fortifications offered a greater degree of passive resistance and more scope for ranged defence in the age of gunpowder artillery. As military architecture, the bastion is one element in the style of fortification dominant from the mid 16th to mid 19th centuries. Evolution By the middle of the 15th century, artillery pieces had become powerful enough to make the traditional medieval round tower and curtain wall obsolete. This was exemplified by the campaigns of Charles VII of France who reduced the towns and castles held by the English during the latter stages of the Hundred Years War, ...
