Equipment

There is no question that the legions of Rome were well led and trained. They were similarly well equipped. Whereas the three ranks of the Polybian legion had each carried widely varying equipment, by the principate, the cohorts, and their respective maniples, were all uniformly armed. The individual arms and armor of the legionary were designed to foster a specific type of close order combat, and they performed that function admirably. Combined with the effectiveness of Roman siegecraft and siege weaponry, their equipment enabled the legions to defeat their opposition in battle and ensured no citadel was unassailable.


Individual Equipment

Each foot soldier wore a linen undergarment and a short-sleeved tunic that came to his knees. The legionary boot was the caliga, heavy sandals studded with hobnails, which had leather thongs winding halfway up the shin. The caliga have received a great deal of attention over the years, both because of the designation "milites caligati" (foot soldier) and due to the famous story detailing the origin of the Emperor Caligula's ("Caligula," meaning "little boot") famous name (Gilliam 185). Over the tunic was worn the lorica segmentata, an iron plate cuirass that covered the chest, stomach, and back. The lorica was by no means universal, as many soldiers wore mail hauberks if they were able to afford it (Simkins 124). Helmets in the Roman legion varied extensively during the period. Helmets could be of bronze or iron, with the Coolus or Imperial-Gallic helmets the norm (Webster 125). The helmets were always open-faced and failed to cover the ears, as it was considered imperative for a soldier to have excellent visibility and hearing on the battlefield. Both types of helmet featured large cheek guards and protective covering for the back of the neck, with the Gallic neck guard sweeping down while the Coolus extended more directly to the rear. The common soldiers wore a plume or forward facing crest, while the centurions wore a transverse crest to more easily identify them. There is some debate as to whether helmet ornamentation was worn in combat, but Caesar seemed to indicate that this is indeed the case when he described an intense moment during the Gallic Wars, "The time was so short, the temper of the enemy so ready for conflict, that there was no space not only to fit crests and decorations in their places, but even to put on helmets and draw covers from shields" (Caesar II, 21).

Each soldier in the Legion was armed with a gladius, two pila, and a scutum. The scutum was the traditional large, rectangular shield, made of layered wood, bound by iron or bronze and covered in leather. The face of the shield was normally decorated, generally in thin plates of bronze. The pilum was the shock weapon of the legionary, used to inflict casualties and hamper the enemy in action. The pilum was roughly 2m long, with the top half composed entirely of iron, ending in a pyramidal point. When thrown, the iron shanks of the pila were designed to bend or break off, leaving the heavy iron half of the weapon stuck in the enemy shield. This both hampered the enemy soldier's ability to use his shield and prevented the pilum from being thrown back. For close combat the legionary was equipped with the legendary gladius hispaniensis. It has been said that the gladius has inflicted more deaths than any other weapon prior to the firearm, and this is very likely true. The gladii were short, double-edged swords with a wide blade. The scabbard was hung from the right side, and the legionary drew the weapon with his right hand. This was necessitated by the large size of the scutum carried in the left, and the gladius was sized to facilitate its being drawn with the right hand (Webster 129). Centurions, officers, and cavalryman were generally equipped with a longer sword, the spatha. Each soldier was also equipped with a pugio, a small triangular shaped dagger.

A legionary on the march was expected to carry a huge amount of gear, dating back to the time of Marius (earning the sobriety "Marius' Mules" for the soldiers). Marius is alleged to have introduced the forked pole used to carry the various entrenching gear, tools, and other equipment a legionary needed to fight and build the nightly defensive camp (Keppie 66). The helmet was normally hung from one of the forks while on the march.

Seige Weapons

The Romans were renowned for their ability to breach walls and invest cities and fortresses. While their engineering prowess played a major role in this, of no less value was the wide array of siege engines they utilized. The most common siege engine was the ram, an enormous beam of wood capped by an iron head shaped like a ram. In order to protect the crew, the testudo arietaria (tortoise), a shed constructed of wood and hides or iron plates, was placed over the ram (Webster 240), allowing the ram to reach the base of the walls.

The legions also utilized a wide array of catapults and other artillery pieces. The largest and most powerful was the onager, named for the wild ass due to its enormous kick. The onager launched massive stones, possibly as heavy as two talents (roughly 50 kg), nearly 500m. The onager utilized only a single, torsion-powered arm to hurl its stones, providing both simplicity and power in one weapon (Baatz). According to Vegetius, each legion had ten onagri, one for each cohort (Webster 243). Among the smaller artillery pieces were the ballistae and its smaller cousin, the scorpiones, torsion powered crossbow-like weapons that fired a stone or bolt. These weapons resembled the medieval heavy crossbows, cocked by a sort of windlass and held by a trigger mechanism. Vegetius indicates that each century carried its own ballistae or scorpiones in a cart called a carro-ballista (Webster 244), giving a legion an impressive array of 60 such weapons. These field artillery pieces were thus mobile, and therefore not restricted to siege use only.

Masada

There can be found no more dramatic an example of the value Rome placed on total victory than the famous siege of Masada. In 72-73 CE, LEGIO X FRETENSIS besieged 967 Jews in one of the most impregnable and imposing fortresses ever constructed (Richmond 4). Amply supplied with water and food, it was impractical to wait out the garrison of Masada-and the Romans were determined that the Jewish revolt, begun in 66 CE, would end here with such finality that there would be no doubts that resistance to Roman rule was futile. The plateau of Masada rises out of an implacable desert like an enormous skyscraper, reaching a height of 300 yards. 730 yards long and 215 yards wide, there are only two paths up: the winding "snake path" to the east that may be navigated single file only, and a slightly wider path to the west (Richmond 142). Masada was thus easily defended, and considered impregnable to any ordinary force. The Romans realized they could not attack along the existing paths, and they could not starve out the garrison. Instead, they set out to build their own path. There was an outcrop to the west, which we know today as White Cliff, and which rises toward Masada. White Cliff falls 137 meters short of the plateau, however (Simkins 113), and the legion was forced to extend the outcrop across empty space while simultaneously raising it. LEGIO X built an enormous ramp from the outcrop and used the position as a platform to fire scorpiones and ballistae upon the defenders, sweeping them from the walls. When the walls were clear, they attacked the walls with a ram, finally setting fire to a newly constructed inner, earthen wall. As night fell, the despairing garrison chose mass suicide rather than face the fate that awaited them. The siege works can still be seen today, a visible testament to the tenacity and skill of Roman military engineering.
