ARMIES AND ENEMIES OF ANCIENT ROME
THE ROMAN ARMY OF THE MID REPUBLIC 275 – 140BC
The Roman army of the mid-Republic (also known as the manipular Roman army or the "Polybian army"), refers to the armed forces deployed by the mid-Roman Republic, from the end of the Samnite Wars (290 BC) to the end of the Social War (88 BC). The first phase of this army, in its manipular structure (290–ca. 130 BC), is described in detail in the Histories of the ancient Greek historian Polybius, writing before 146 BC.
The central feature of the mid-Republican army was the manipular organisation of its battle-line. Instead of a single, large mass (the phalanx) as in the Greek and Early Roman army, the Romans now drew up in three lines (triplex acies) consisting of small units (maniples) of 120 men, arrayed in chessboard fashion, giving much greater tactical strength and flexibility.
The velites would gather at the front, and cover the advance of the hastati. If the hastati failed to break the enemy, they would fall back on the Principes. If the principes could not break them then they would retire behind the Triarii.
This order of battle was almost always followed. It was Scipio Africanus at the Battle of The Great Plains, and the Battle of Zama, who modified this tactic.
NEW MID REPUBLICAN ROMAN PRINCIPES
For set-piece battles, the heavy infantry were usually drawn up in three lines.
However, the vast majority of the heavy infantry were stationed in the front two lines, the HASTATI and PRINCIPES. Contained in these two lines were the younger recruits who were expected to do all the fighting. The rear line (TRIARII), was a reserve consisting of older men who formed a line of last resort to provide cover for the front lines if they were put to flight (and also to prevent unauthorised retreat by the front ranks).
The Principes (singular princeps) were originally men in the prime of their lives , who were also fairly wealthy, and could therefore afford decent equipment. These were the heavier infantry of the legion, and their usual position was the second battle line.
By the time of the Punic wars infantry were sorted into classes according to age and experience rather than wealth. The Principes then became the older veterans but their equipment and role remained the same.
NEW MID REPUBLICAN ROMAN HASTATI
Hastati (singular: Hastatus) were a class of infantry employed in the armies of the early and Mid Roman Republic.
They were originally some of the poorest men in the legion, and could afford only modest equipment. Later, the hastati contained the younger men rather than just the poorer, (though most men of their age were relatively poor.) Their usual position was the first battle line.
The hastati were formed into 10 maniples of 120 men each, therefore 1,200 men per legion.
Battles were conducted in a similar fashion; the velites would gather at the front and fling javelins to cover the advance of the hastati. If the hastati failed to break the enemy, they would fall back on the principes.
If the principes could not break the enemy, they would retire behind the triarii, who would then engage.
NEW ROMAN AUXILLIARY CAVALRY
As Romans were never considered exceptionally good horsemen, and the role of the cavalry not as important in the Roman thought process, the Equitatus was generally made up of non-Roman horsemen. While they would play an important part of Legionary tactics, the Roman Cavalry was considered secondary and would remain the weakest part of the Roman Army until the very late Imperial period.
Generally, the cavalry was used as light skirmishing troops, and mounted archers whose job was to patrol, act as scouts and messengers and to provide a mobile defensive screen while the legion was massing in battle array. As in all armies throughout history, the mounted trooper was also very effective in chasing down and harassing a fleeing and panicked enemy force.
As part of the military reforms of Augustus around AD 14, the Auxilia were re-organized. They would be trained to the same standards of discipline as the legions. They were mainly drawn from a wide range of warlike peoples throughout the provinces, and would receive Roman citizenship on completion of their 25 year sevice. Senior officers in contrast were Roman citizens.
The Auxilia filled the tasks of patrolling, containing raids, tax collecting, and the multitude of duties of the frontier troops.
They were especially suited to garrison and local policing activities, and could also hold their own in small scale warfare.
Roman Auxilia cavalry were usually heavily armored in mail and armed with a short lance, javelins, the Spatha long sword, and sometimes bows for specialist Horse archer units. These men primarily served as Medium missile cavalry for flanking, scouting, skirmish, and pursuit
