Ancient warfare

Ancient warfare is war that was conducted from the beginning of recorded history to the end of the ancient period. The difference between prehistoric and ancient warfare is more organization oriented than technology oriented. The development of first city-states, and then empires, allowed warfare to change dramatically. Beginning in Mesopotamia, states produced sufficient agricultural surplus. This allowed full-time ruling elites and military commanders to emerge. While the bulk of military forces were still farmers, the society could portion off each year. Thus, organized armies developed for the first time. These new armies were able to help states grow in size and become increasingly centralized.
In Europe and the Near East, the end of antiquity is often equated with the Fall of Rome in 476 AD, the wars of the Eastern Roman Empire on its Southwestern Asian and North African borders, and the beginnings of the Muslim conquests in the 7th century. In China, it can also be seen as ending of the growing role of mounted warriors needed to counter the ever-growing threat from the north in the 5th century and the beginning of the Tang dynasty in 618 AD. In India, the ancient period ends with the decline of the Gupta Empire and the beginning of the Muslim conquests there from the 8th century. In Japan, the ancient period is considered to end with the rise of feudalism in the Kamakura period in the 12–13th century.
Early ancient armies continued to primarily use bows and spears, the same weapons that had been developed in prehistoric times for hunting. The findings at the site of Nataruk in Turkana, Kenya, have been interpreted as evidence of inter-group conflict and warfare in antiquity, but this interpretation has been challenged. Early armies in Egypt and China followed a similar pattern of using massed infantry armed with bows and spears.
Infantry at this time was the dominant form of war, partially due to the camel saddle and the stirrup not being invented yet. The infantries at this time would be divided into ranged and shock, with shock infantry either charging to cause penetration of the enemy line or hold their own. These forces would ideally be combined, thus presenting the opponent with a dilemma: group the forces and leave them vulnerable to ranged, or spread them out and make them vulnerable to shock. This balance would eventually change as technology allowed for chariots, cavalry, and artillery to play an active role on the field.
No clear line can be drawn between ancient and medieval warfare. The characteristic properties of medieval warfare, notably heavy cavalry and siege engines such as the trebuchet were first introduced in Late Antiquity. The main division within the ancient period is at the beginning Iron Age with the introduction of cavalry, of naval warfare, and the development of an industry based on ferrous metallurgy which allowed for the mass production of metal weapons and thus the equipment of large standing armies.
The first military power to profit from these innovations was the Neo-Assyrian Empire, which achieved a hitherto unseen extent of centralized control, the first "world power" to extend over the entire Fertile Crescent.

Chariots

As states grew in size, the speed of mobilization became crucial because central power could not hold if rebellions could not be suppressed rapidly. The first solution to this was the chariot, which was initially used in the Middle East from around 1800 BC. First pulled by oxen and donkeys, they allowed rapid traversing of the relatively flat lands of the Middle East. The chariots were light enough that they could easily be floated across rivers. Improvements in the ability to train horses soon allowed them to be used to pull chariots, possibly as early as 2100 BC, and their greater speed and power made chariots even more efficient. The major limitation of the use of chariots was terrain; while very mobile on flat, hard, open ground, it was very difficult to traverse more difficult terrain, such as rough ground, even sparse trees or bushes, small ravines or streams, or marsh. In such terrain, chariots were less maneuverable than common foot soldiers, and later cavalry.
The chariot was so powerful for transportation and warfare that it became the key weapon in the Ancient Near East in the 2nd millennium BC. The typical chariot was worked by two men: one would be a bowman who would fire at enemy forces, while the other would control the vehicle. Over time, chariots were developed to carry up to five warriors. In China, chariots became the central weapon of the Shang dynasty, allowing them to unify a great area.
Although chariots have been compared to modern-day tanks in the role they played on the battlefield, i.e. shock attacks, this is disputed, with scholars pointing out that chariots were vulnerable and fragile, and required a level terrain while tanks are all-terrain vehicles; thus chariots were unsuitable for use like modern tanks as a physical shock force. The chief advantage of the chariot was the tactical mobility they provided to bowmen. Tightly packed infantry was the formation of choice, in order for ancient generals to maintain command and control during the battle as well as for mutual protection. But a force of chariots could stand off at long range and rain arrows down on the infantrymen's heads. Because of their speed, any attempts to charge the chariots could be easily evaded. If, on the other hand, an infantry unit spread out to minimize the damage from arrows, they would lose the benefit of mutual protection and the charioteers could easily overrun them.
Thus any force facing chariots was in a tactical dilemma, making chariots indispensable to armies of those times. But they were complicated equipment that required specialized craftsmen to maintain them. This made chariots expensive to own. When chariots were owned by individuals within a society, it tended to give rise to a warrior class of specialists and a feudal system. Where chariots were publicly owned, they helped in the maintenance and establishment of a strong central government, e.g. the New Egyptian Kingdom. Chariot usage peaked in the Battle of Kadesh in 1274 BC, which was probably the largest chariot battle ever fought, involving perhaps 5,000 chariots.

Naval warfare

Naval warfare in the ancient world can be traced back to the Mediterranean in the third millennium BC, from evidence of paintings in the Cyclades and models of ships which were made across the Aegean. Ships were used for civilian transport and trade, as well as for military purposes. They were propelled by both rowing and sailing, but since the Mediterranean is known for its inconsistent weather patterns, rowing was probably the primary means of propulsion.
The first documented, physical evidence of a naval battle is found in a relief painting located in the temple of Medinet Habu, near Luxor, Egypt. It shows the victory of Ramses III over the 'Sea-Peoples' in the Nile river delta in the early twelfth century BC. These 'Sea-Peoples' were originally believed to be of Philistine and Phoenician descent, while there is speculation that there could be some Greek influence in their seafaring. Even before this relief painting, there are earlier records of the practice of sea battles as early as 2550 BC under the Egyptian pharaoh Sahue, who reportedly used transport vessels to escort his armies to foreign shores. There is even further evidence from earlier sources that illustrate seafaring and military action around the Nile Delta during the early dynastic period in Egypt, following into the reign of Ramses II
Before that victory of Ramses III, the state of Egypt had no access to the kind of timber needed to build seafaring vessels and warships on a large scale. Instead of importing large quantities of timber to build warships, Egyptian naval architects and early engineers began to convert the common Egyptian riverboats. They reconfigured the size of the ship and added heavy trees for longitudinal support of the hull on the open sea. The warships constructed in this way contributed to that victory. The relief painting shows in great detail how fighting was conducted in a naval battle. It shows Egyptian warships with over twenty rows of oarsmen along with infantry troops and archers fighting in apparent hand-to-hand combat with the opposing naval force. This raises a question to the theory that there was no actual naval weaponry developed at this time but rather a reliance upon maneuvering tactics and strategy in order to engage with infantry troops.

The trireme

Among the great innovations of naval warfare in the ancient world there are few that can surpass the trireme style warship in terms of efficiency, strategy, and overall effectiveness. The first depiction of this 'longship' style vessel can be found in Homer's The Iliad as a means of transport of armed men and supplies to areas of conflict across the seas. These ships were said to have consisted of two separate levels that could have held up to 60 men per level, all operating oars in unison to propel the ship. The upper level of oarsmen would sit in single-file fashion, pulling their oars through what is called a top wale or some sort of oar-port; while the men in the lower rows would sit in the ships' hold also rowing through lower oar-ports. It is also said that each oar throughout the ship would be made in length proportionate to the physique of an average Greek man.
Manned crews for these massive warships would have been quite impressive, but accounts vary in actual numbers of men from source to source. Herodotus of Halicarnassus was a Greek historian in the fourth century BC who, through his accounts, said that these triremes would consist of at least two hundred men manning all positions. With these massive crews, these ships were able to work at maximum capacity and efficiency in regards to speed, navigation, and transport. While these ships were built for maximum efficiency, there is room for debate about the conditions and space aboard the ship itself. It is estimated that out of the 200 man crew, around 170 of those men would have been oarsmen with respective positions below deck. These oarsmen below deck would sit on thwarts and kept their personal storage items beneath them, reassuring the theory that these ships would be very crowded with little room for anything other than operational functions.
What exactly these Greek triremes were capable of in battle is debated. There are various different accounts that lay down foundations of what equipment was used and how these ships engaged in combat. The main military applications of Greek triremes, besides the transport of troops and supplies, would be the advantages of ramming tactics. Developments and innovations of the Greek trireme evolved over time, especially in respect to ramming tactics. Naval architects during this time saw fit to bring about full effectiveness and damaging power to these ships. By doing this, the amount of manpower would stay consistent, i.e., keeping the same amount of rowing power but shortening the length of the ship to condense the ramming power while keeping speed and agility consistent. This new ideology of warfare and naval tactics would prove to be prudent to the overall military applications of the trireme, and soon would become the principal combative strategy of the Greek navy and other navies alike.
The Greek trireme, soon after its appearance in the Aegean, would become the standard warship throughout the Mediterranean as sovereign states such as Egypt and the Persian Empire would adopt the design of these ships and apply them to their own military applications. One major attraction of the Greek design was not only its efficient ramming capability but also its ability to travel long distances at fair speeds. One account from the Athenian soldier and historian Xenophon describes the voyage of the Athenian fleet commander Iphicrates through unfriendly waters and the strategy he used combined with the sheer sailing power of the trireme.
This primary source account can be interpreted as functional and efficient use of the Greek trireme: maximizing its speed through rugged and unfriendly seas while also utilizing specific military strategy in order to ensure the most prudent and effective outcome was what led to the success of the trireme across all kinds of empires and civilizations throughout the Mediterranean. The trireme would later become a vital piece of naval weaponry throughout the Persian Wars, for both the Greeks and the Persian Empire, as well as the base standard for the formation of the Roman navy.
The Persian Wars were the first to feature large-scale naval operations: not only sophisticated fleet engagements with dozens of triremes on each side, but also combined land-sea operations. Ships in the ancient world could operate only on the relatively quiet waters of seas and rivers; the oceans were off limits. Navies were almost always used as auxiliaries to land forces, often essential to bringing them supplies. They would rarely strike out on their own. With only limited-range weapons, naval galleys would often attempt to ram their opponents with their reinforced bow to cause damage or sink the enemy warships which often caused the two ships to become joined, and initiated a boarding battle. Only occasionally was a decisive naval battle fought, such as the Battle of Lade in which a Persian navy destroyed the Greek navy.
