Description
Hastati (singular: Hastatus) were a class of infantry in the armies of the early Roman Republic who originally fought as spearmen, and later as swordsmen. They were originally some of the poorest men in the legion, and could afford only modest equipment — light armour and a large shield, in their service as the lighter infantry of the legion. 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. They fought in a quincunx formation, supported by light troops. They were eventually done away with after the Marian reforms of 107 BC.
History and deployment
Hastati appear to have been remnants of the old third class of the army under the Etruscan kings when it was reformed by Marcus Furius Camillus. The third class stood in some of the last few ranks of a very large phalanx were equipped in a similar manner to hastati, but more often than not were relegated to providing missile support to the higher classes rather than fighting themselves. It is probable that engagements with the Samnites and a crushing defeat at the hands of the Gallic warlord Brennus, who both used lots of smaller military units rather than a few very large ones, taught the Romans the importance of flexibility and the inadequacy of the phalanx on the rough, hilly ground of central Italy.
Camillan system
The war against the gauls forced the romans to reform their army.By the 4th century BC the military the Romans had inherited from the Etruscans was still in use. Though its efficiency was doubtful, it proved effective against Rome's largely local adversaries. When Gauls invaded Etruria in 390 BC, the inhabitants requested help from Rome. The small contingent Rome sent to repel the Gallic invaders provoked a full scale attack on Rome. The entire Roman army was destroyed at the Battle of the Allia in a crushing defeat that prompted reforms by Marcus Furius Camillus.
Under the new system, men were sorted into classes based on wealth; the hastati were the third poorest, with the rorarii being slightly poorer and the principes slightly wealthier. Hastati were armed with short spears, or hastae, up to 1.8 metres (6 ft) long, from which the soldiers acquired their name. They fought in quincunx formation, usually carrying scuta, large rectangular shields, and bronze helmets, often with a number of feathers fixed onto the top to increase stature. They wore light armour, the most common form being small breastplates, called "heart protectors".
In this type of legion, the 900 hastati formed 15 maniples, military units of 60 men each. Attached to each maniple were about 20 leves, javelin-armed light infantry. The hastati stood in the first battle line, in front of the principes of the second line and the triarii of the third. In a pitched battle, the leves would form up at the front of the legion and harass the enemy with javelin fire to cover the advance of the hastati. If the hastati failed to break the enemy during their engagement, they would fall back and let the heavier principes take over. If the principes could not break them, they would retire behind the triarii spearmen, who would then engage the enemy in turn. The equites, cavalrymen, were used as flankers and to pursue routing enemies. The rorarii and accensi in the final battle line were some of the least dependable troops, and were used in a support role, providing mass and reinforcing wavering areas of the line.
Polybian system
The hastati were replaced by legionaries. By the time of the Punic wars of the 3rd century BC, the Camillan system of organisation was found to be inefficient. In a new Polybian system, infantry were sorted into classes according to age and experience rather than wealth, the hastati being the youngest and least experienced. Their equipment and role was very similar to the previous system, except they now carried swords, or gladii, instead of spears. Each hastatus also carried 2 pila, heavy javelins that bent on impact to prevent them being removed from the victim or thrown back.
The hastati had been increased in number to 1200 per legion, and formed 10 maniples of 120 men each. The rorarii and accensi had been done away with. Leves had been replaced with velites, who had a similar role but were now also attached to principes and triarii. Pitched 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, who had also been re-armed with swords. If the principes could not break them, they would retire behind the triarii, who would then engage the enemy.
This order of battle was almost always followed, the battle of the Great Plains and the battle of Zama being among the few notable exceptions. At the Great Plains, Scipio, the Roman general, formed his men up in the usual manner, but once the hastati had begun to engage the enemy, he used his principes and triarii as a flanking force, routing the opposing Carthaginian troops.
The hastati disappeared with the creation of professional legions. At Zama, Scipio arranged his men into columns, side by side, with large lanes in between. The opposing Carthaginian elephants were drawn into these lanes where many were killed by velites without inflicting many casualties on the Romans. Once the surviving elephants had been routed, he formed his men into a long line with his triarii and principes in the centre and hastati on the flanks, ready to engage the Carthaginian infantry.
Marian reforms
With the formal military reforms of Gaius Marius in 107 BC, intended to combat a shortage of manpower from wars against Jugurtha in Africa and Germanic tribes to the north, the different classes of units were done away with entirely. The wealth and age requirements were scrapped. Soldiers would join as a career, rather than as service to the city, and would all be equipped as medium infantry with the same state-purchased equipment. Auxiliaries, local irregular troops, would fulfill other roles, serving as archers, skirmishers and cavalry
Use in FOG
Hastati (and their interchangable chums the Principes) are the core unit of the MRR army.They are Heavy Foot, Protected, Average, Drilled, Impact Foot Swordsmen.
They can be upgraded to Armoured and Superior. Both upgrades are highly recommended. Although the points tally can rise from 8 per base to 14 per base, the POA for being better armoured and the ability to re-roll 1's makes them virtually unstoppable against any but the best opposing units on the field.
Their disadvantage is the small number of units per BG - although as Superior they can go on until they lose the 3rd base. As a consequence the Roman commander should consider placing his hastati / principes in an area where both flanks are protected and encourage the opposition to come onto them.
The small numbers and slow movement (3MU's) means that caught in the open by more flexible troops can make them vulnerable. But in a head on fight they are tough opponents.
Movement
Hastati only move at 3MU and so aren't going anywhere quickly. They are drilled and so can move around relatively easily - just not very quickly.
Laying the troops out in the traditional Roman checkerboard formation allows for easier movement before battle is joined (such as aligning troops against units they'll get a better POA against) and - when battle is joined - to move units up to prevent overlaps and present a solid line.
As an example, a BG of 4 bases of hastati with a BG of 2 triarii behind and to the right engages a BG of 6 bases of Gallic warriors. The Roman general can move the triarii into line next to the hastati OR wait until after the impact and melee. If the hastati are doing well (say the Gauls are disrupted) then the triarii can move in and Impact the Gauls while they are at a disadvantage. Similarly if the hastati fared less well at impact they can move up to support the hastati. Or they can stay where they are and threaten / intercept a flank attack should one look likely.
Impact / melee
Hastati are armed with pila and short sword. They are Impact Foot (++ against any foot and + against most mounted).
Hastati suffer against elephants who get a + against them so it is worth screening hastati with velites where elephants are present or (if possible) lining your triarii up against opposing elephants.
They also suffer against chariots in open terrain at Impact so if your opponent has chariots you will want to place your hastati in a position where the chariots are less effective (e.g. behind terrain or on a hill).
Hastati do very well against foot swordsmen (usually getting ++ in melee when their better armour is taken into account). As a consequence Roman commanders should aim the hastati at any medium or heavy sword-armed troops in preference to any other. They also do well against Heavy Weapon armed troops in melle (being Skilled Swordsmen).
They do quite well against most cavalry in impact and hand-to-hand (usually having a + POA) unless facing lancers. With a BG of triarii in close attendance, this makes a cavalry attack on hastati a very high risk strategy.
Skirmish troops shooting at hastati tend to be ineffective - the armour + usually means that missile fire has little if no impact. But the velites should keep skirmishers away in any case.
Hastati do less well against spears (I always try to avoid Carthaginian African Spearmen for this reason) as they lose a + at impact and their + in melee (indeed they can often fight at a disadvantage). This includes pikes, offensive spearmen and light spear. The drilled nature of the hastati may make it possible to move them away from the threat of a spear charge.
A usual counter to the hastati is to throw cheap impact troops (gallic warriors, scutarii) at the hastati in the hope of wearing them down before the 'better' units (such as spearmen) arrive on the scene. This is a high risk strategy because if the hastati survive the Impact in good shape, then the attacking BG is likely to suffer heavy casualties and be routed. However, if successful then the small numbers of Romans can be quickly whittled down.
