Pilum (Latin pilum, plural pila) — a throwing spear (dart) used by the legions of Ancient Rome. The pilum was as much an integral part of a Roman legionary's armament as the gladius or scutum. This unusual spear was no less formidable than the legionary swords and auxilar spears, and wherever the legion went, each legionary carried one or more pilums on his shoulder, in addition to the furka (cross-shaped carrier on which personal belongings were carried), waiting for his turn to make a blood sacrifice for the glory of Mars.
It is not known exactly when and under what circumstances the Romans first started using the pilum. It is known that it was used even before the 4th century BC, according to one version, it could have been borrowed from the Samnites, Sabines, or Etruscans, who had darts vaguely similar to the pilum for fishing. Anyway, the Roman army used pilums, initially, apparently, arming only velites (lightly armed and mobile soldiers) and Hastati (heavily armed soldiers) with them.
During the reforms of Colonel Gaius Marius (157-86 BC), the purpose of which was to reorganize the legions, the purpose of the scutum also changed - now it was worn by all legionaries, respectively, the tactics of combat and the structure of the pilum itself underwent some changes. Subsequently, the pilum underwent some minor changes, mainly related to the method of attaching the tip to the shaft, changes in weight, and the softness of the metal from which the tips were made. It is believed that each legionnaire carried with him two pilums, different in weight. By the end of the Roman Empire, the pilum was gradually being removed from the legions ' armament, replaced by a lighter spiculum, according to Vegetius.
Since the pilum is a throwing spear, its main purpose was to defeat the enemy at a relatively short distance. Directly in combat, the pilum was thrown by legionnaires at the enemy at a distance of up to 35 meters, in order to cause confusion in the enemy formation. In addition, a direct hit of the pilum tip was a very formidable factor, since heavy variations of this dart were able to penetrate armor and cause terrible injuries, but the pilum that hit the shield served a certain purpose - it actually deprived the enemy of protection, significantly weighing down his shield, not allowing them to maneuver quickly. And freeing the shield from the pilum was a very difficult task - the jagged pommel was tightly stuck in the shield, and the long iron tip did not allow cutting off the stuck spear. As a result, the enemy was forced to drop his shield, leaving him defenseless right before a hand-to-hand clash with the formation of legionnaires.
In his" Notes on the Gallic War, "Caesar vividly described the effect produced by a volley of pilums thrown at the enemy:" Since the soldiers let their heavy spears fly from above, they easily broke through the enemy's formation... ...A great obstacle to the Gauls was that the Roman spears sometimes with one blow punched several boards at once, and so were nailed them to each other, and when the tip was bent, it was impossible to get and the soldiers were not able to fight, as movements with the left hand was difficult; in the end, many long shaking hand, preferred to throw the shield and fight with the whole body open."
There is also a mention of using the pilum as a regular spear. In particular, it was this use of throwing spears that made a certain contribution to the victory of Gaius Julius Caesar over Gnaeus Pompey at the Battle of Pharsalus (48 BC). "Noticing that the enemy's left flank consisted of numerous cavalry, Caesar transferred six reserve cohorts to himself and placed them behind the tenth legion, ordering them not to show themselves to the enemy until they were at close range, then to run out of the ranks, but not to throw pilums, but to fight with them as close-range spears effective against cavalry... ...Pompey waited to see what the cavalry would do. She was already extending the line of her squadrons to outflank Caesar and drive his small cavalry back to the infantry. At this moment Caesar gave a signal, and his cavalry parted, and the three thousand men in reserve advanced to meet the enemy. As they did so, they began to strike upward with their spears and point them in the face. The cavalry, inexperienced in such battles, became timid and could not bear to be hit in the eyes. The horsemen, covering their faces with their hands, turned their horses and turned into a shameful flight."
In the third and second centuries BC, the tip of the pilum was usually much shorter than the later, most well-known variants. Short tips did not exceed a length of 30-40 cm, and had a wide flat shape. Already in the middle of the second century AD, the pilum consisted of a long iron tip, approximately equal in length to the shaft, and had a total weight of 1 to 2.5 kg, depending on the specific model. The total average length of the pilum was usually 2 m, the tip was 60 cm long, although some finds reach a length of 90 cm. From the bottom, the shaft often had an iron tip for sticking the pilum into the ground, if necessary.
The thickness of the tip was usually about 7 mm, while the pommel was jagged or pyramidal. There were several different ways of attaching the tip to the shaft, for example, the "sleeve" method - an expanding cavity was made at the end of the tip, which was put on the tip of the shaft, or the most common fastening using a flat tongue, which was also attached to the shaft with several rivets, initially iron, and later wooden.
The introduction of wooden rivets by Gaius Marius was caused by the need to exclude the reuse of abandoned pilums already against the Romans. As a rule, the tips of the pilums were made of rather soft materials and were not tempered, which, when hit by an enemy shield, led to a bend in the tip, and, as a result, the saw blade was unusable for reuse. However, it was noted that the tip often did not bend, so the wooden rivets served as a solution to this problem, leading to the failure of the pilum. Since the late Republic, bas-reliefs sometimes show pilums with spheres attached to them, which were supposedly made of metal, and were attached at the end of the shaft. Their purpose was, apparently, to increase the weight of the projectile, and, as a result, its penetration force.
First of all, you need to determine the tasks that will be assigned to the reconstructed pilum sample, and based on certain tasks, choose the direct type of reconstruction. In other words, to recreate the image of a legionnaire and to reproduce the equipment of Roman soldiers, a pilum made "according to the combat" model, that is, made of wood and iron, is most likely suitable. In 1998, the English historian Peter Connolly recreated some samples of pilums for field testing in order to establish their real effectiveness on the battlefield. During tests of penetration, it was found that the pilum of the early Empire model could penetrate a sheet of plywood 11 mm thick, despite the fact that because of the pyramidal tip, it was difficult to reach, and the tip itself was curved, according to narrative sources.
Our club also conducted tests of the penetration ability of this weapon, which confirmed that the pilum is an extremely formidable weapon. From a distance of several meters, a pilum was thrown at the target, which served as a pork carcass covered with a small shield. Pilum not only pierced through the shield, but also the "enemy" who was hiding behind it, causing injuries incompatible with life.
