Siege Engine
A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls and other fortifications in siege warfare. Some are immobile, constructed in place to attack enemy fortifications from a distance, while others have wheels to enable advancing up to the enemy fortification. There are many distinct types, such as siege towers that allow foot soldiers to scale walls and attack the defenders, battering rams that damage walls or gates, and large ranged weapons (such as ballistas, catapults/ trebuchets and other similar constructions) that attack from a distance by launching heavy projectiles. Some complex siege engines were combinations of these types. Siege engines are fairly large constructions – from the size of a small house to a large building. From antiquity up to the development of gunpowder, they were made largely of wood, using rope or leather to help bind them, possibly with a few pieces of metal at key stress points. They could la ...

Battering Ram
A battering ram is a siege engine that originated in ancient times and was designed to break open the masonry walls of fortifications or splinter their wooden gates. In its simplest form, a battering ram is just a large, heavy log carried by several people and propelled with force against an obstacle; the ram would be sufficient to damage the target if the log were massive enough and/or it were moved quickly enough (that is, if it had enough momentum). Later rams encased the log in an arrow-proof, fire-resistant canopy mounted on wheels. Inside the canopy, the log was swung from suspensory chains or ropes. Rams proved effective weapons of war because at the time wall-building materials such as stone and brick were weak in tension, and therefore prone to cracking when impacted with force. With repeated blows, the cracks would grow steadily until a hole was created. Eventually, a breach would appear in the fabric of the wall, enabling armed attackers to force their way thr ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Greece
Ancient Greece () was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity (), that comprised a loose collection of culturally and linguistically related city-states and communities. Prior to the Roman period, most of these regions were officially unified only once under the Kingdom of Macedon from 338 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age collapse, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece, from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War.

Assyria
Assyria (Neo-Assyrian cuneiform: , ''māt Aššur'') was a major ancient Mesopotamian civilization that existed as a city-state from the 21st century BC to the 14th century BC and eventually expanded into an empire from the 14th century BC to the 7th century BC. Spanning from the early Bronze Age to the late Iron Age, modern historians typically divide ancient Assyrian history into the Early Assyrian period, Early Assyrian ( 2600–2025 BC), Old Assyrian period, Old Assyrian ( 2025–1364 BC), Middle Assyrian Empire, Middle Assyrian ( 1363–912 BC), Neo-Assyrian Empire, Neo-Assyrian (911–609 BC), and Post-imperial Assyria, post-imperial (609 BC– AD 240) periods, based on political events and gradual changes in language. Assur, the first Assyrian capital, was founded 2600 BC, but there is no evidence that the city was independent until the collapse of the Third Dynasty of Ur, in the 21st century BC, when a line of independent kings starting with Puzur-Ashur I began rulin ...

Middle Kingdom Of Egypt
The Middle Kingdom of Egypt (also known as The Period of Reunification) is the period in the history of ancient Egypt following a period of political division known as the First Intermediate Period of Egypt, First Intermediate Period. The Middle Kingdom lasted from approximately 2040 to 1782 BC, stretching from the reunification of Egypt under the reign of Mentuhotep II in the Eleventh Dynasty of Egypt, Eleventh Dynasty to the end of the Twelfth Dynasty of Egypt, Twelfth Dynasty.

The Periodization of ancient Egypt, concept of the Middle Kingdom as one of three golden ages was coined in 1845 by German Egyptologist Christian Charles Josias von Bunsen, Baron von Bunsen, and its definition evolved significantly throughout the 19th and 20th centuries. Some scholars also include the Thirteenth Dynasty of Egypt wholly into this period, in which case the Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scaling Ladder
Escalade is the act of scaling defensive walls or ramparts with the aid of ladders. Escalade was a prominent feature of sieges in ancient and medieval warfare. Although no longer common in modern warfare, escalade technologies are still developed and used in certain tactical applications. Overview Escalade consists of attacking soldiers advancing to the base of a wall, setting ladders, and climbing to engage the defending forces. Though very simple and direct, it was also one of the most dangerous options available; escalade would generally be conducted in the face of arrow fire from the battlements, and the defenders would naturally attempt to push ladders away from the wall. Heated or incendiary substances such as boiling water, heated sand, and pitch-coated missiles were sometimes poured on attacking soldiers. This made it difficult for attackers to reach the top of the wall, and those that did would often quickly be overwhelmed by the defenders on the walls, only be ...

Siege Train
In military contexts, a train is the logistical transport elements accompanying a military force. Often called a supply train or baggage train, it has the job of providing materiel for their associated combat forces when in the field. When focused on provision of field artillery and its ammunition, it may be termed an artillery train. For sieges, the addition of siege engines to an artillery train was called a siege train. These military terms predate and do not imply a railway train, though railways are often employed for modern logistics and can include armoured trains. For armies, this historically usually referred to forces employing wagons, horses, mules, oxen, camels, or even elephants. These can still be useful where difficult weather or topography limit use of railways, trucks, sealift, or airlift. The United States Department of Defense ''Dictionary of Military and Associated Terms'' defined the term "train" as: History Antiquity In the Ancient Macedonian army ...

Ammunition
Ammunition, also known as ammo, is the material fired, scattered, dropped, or detonated from any weapon or weapon system. The term includes both expendable weapons (e.g., bombs, missiles, grenades, land mines), and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected Targeting (warfare), target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm Cartridge (firearms), cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sapper
A sapper, also called a combat engineer, is a combatant or soldier who performs a variety of military engineering duties, such as breaching fortifications, demolitions, bridge-building, laying or clearing minefields, preparing field defenses, and road and airfield construction and repair. Sappers are also trained and equipped to serve secondarily as provisional infantry. Sappers facilitate and support the movement, defense, and survival of superordinate and allied forces, and impede those of enemies. The term "sapper" is used in the British Army and Commonwealth nations, the U.S. military, and the militaries of other countries. Historical origin Sapper A sapper, in the sense first used by the French military, was one who dug trenches to allow besieging forces to advance towards the enemy defensive works and forts over ground that is under the defenders' musket or artillery fire. It comes from the French word ''sapeur'', itself being derived from the verb ''saper'' (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
