Dacian warfare

The history of Dacian warfare spans from c. 10th century BC up to the 2nd century AD in the region defined by Ancient Greek and Latin historians as Dacia, populated by a collection of Thracian, Ionian, and Dorian tribes. It concerns the armed conflicts of the Dacian tribes and their kingdoms in the Balkans. Apart from conflicts between Dacians and neighboring nations and tribes, numerous wars were recorded among Dacians too.

Tribal wars
The Dacians fought amongst each other but were later united under Burebista. However, after his death in 44 BC, the empire again descended into conflict culminating in a full-scale civil war. This led to the division of Burebista's empire into five separate kingdoms, severely weakening the Dacian's defensive capabilities against enemies, particularly Rome. The Dacian tribes were again consolidated under Decebalus, who achieved several military victories in a series of battles with the forces of Emperor Domitian.

Domitian's Dacian War
The two punitive expeditions mounted as a border defense against raids of Moesia from Dacia in 86-87 AD ordered by the Emperor Titus Flavius Domitianus (Domitian) in 87 AD, and 88 AD. The first expedition was an unmitigated disaster, and the second achieved a peace, seen as unfavorable and shameful by many in Rome.

Trajan's Dacian Wars
Trajan's Dacian Wars. The two campaigns of conquest ordered or led by the Emperor Trajan in 101-102 AD, and 105-106 AD from Moesia across the Danube north into Dacia. Trajan's forces were successful in both cases, reducing Dacia to client state status in the first, and taking the territory over in the second. These wars involved no fewer than 13 legions. The defeat reduced the Dacian territory as a mere Roman province. Rome ruled it, including the entire Transylvanian basin for 150 years. A succession of migratory waves by Visigoths, Huns, Gepids, Avars, and Slavs overran Dacia, cutting it off from the Roman and the Byzantine empires by the end of the sixth century.

Dacian troop types and organization
The Dacians, like any other barbarian nation, never fielded a standing army, even though there was a warrior class of sorts, the comati, meaning "long-haired people". Instead, local chieftains, the pileati, meaning "cap-wearing people", raised a levy when required, a force only available after the harvesting season ended. The men themselves fought in everyday clothing defended merely by an oval shield, for body armor and helmets were only worn by the nobility.

Infantry and cavalry
The Dacian tribes established a highly militarized society and, during the periods when the tribes were united under one king (82 -44 BC, 86-106 AD), posed a major threat to the Roman provinces of Lower Danube. Julius Caesar made preparations for war with King Burebista to prevent an invasion of Macedonia, however both rulers died in the same year. Dacia lost control over territories beyond the Danube and Tisza and collapsed into hostile fractions, now being able to master only 40,000 men from the previous 200,000. Dacia, however remained a formidable foe: in the winter of 10 BC, a raid across the Danube was repulsed by Marcus Vinicius. After some decades, the invasions restarted. A major one was just checked in 69 by Licinius Mucianus while on his way to battle Aulus Vitellius. In another one in 85 the Romans have almost lost Moesia, and its governor Oppius Sabinus was killed. The following year a Dacian force annihilated the army of Cornelius Fuscus under the new leader Decebalus after the victory of Tettius Julianus at Tapae. As the war dragged on, Domitian was distracted by the Suebians and Iazyges, and had to make a humiliating peace. Later Trajan had attacked Decebalus two times, first making peace before reaching the capital, then taking it and conquering around a third of Dacia. According to Criton of Heraclea, the 500,000 POWs were taken. The Free Dacians, allying with Scythian and Germanic tribes never stopped raiding the new Roman province. After the sound of the carnyx war trumpet, the Dacians went to battle with the draco. The most important weapon of their arsenal was the falx. This dreaded weapon, similar to a large sickle, came in two variants: a shorter, one-handed falx called a sica, and a longer two-handed version, which was a polearm. It consisted of a three-feet long wooden shaft with a long curved iron blade of nearly-equal length attached to the end. The blade was sharpened only on the inside, and was reputed to be devastatingly effective. However, it left its user vulnerable because, using a two-handed weapon, the warrior could not also make use of a shield. Alternatively, it might be used as a hook, pulling away shields and cutting at vulnerable limbs.

Using the falx, the Dacian warriors were able to counter the power of the compact, massed Roman formations. During the time of the Roman conquest of Dacia (101 - 102, 105 - 106), legionaries had reinforcing iron straps applied to their helmets. The Romans also introduced the use of leg and arm protectors (greaves and manica) as further protection against the falxes. This was one of the rare times in history where Roman armor was modified.



The Dacians were adept at surprise attacks and skillful, tactical withdrawals using the fortification system. During the wars with the Romans fought by their last king Decebalus (87-106), the Dacians almost crushed the Roman garrisons south of the Danube in a surprise attack launched over the frozen river ( winter of 101-102 ). Only the intervention of Emperor Trajan with the main army saved the Romans from a major defeat. But, by 106, the Dacians were surrounded in their capital Sarmizegetusa. The city was taken after the Romans discovered and destroyed the capital's water supply line.

Dacians decorated their bodies with tattoos like the Illyrians and the Thracians. The Pannonians north of the Drava had accepted Roman rule out of fear of the Dacians.

Dacia remained a Roman province until 271.

Marcus Annaeus Lucanus 39 - 65 wrote of Dacian hordes;

"Have poured her captains, and the troops who guard the northern frontier from the Dacian hordes"

Dacians that could afford armor wore customised Phrygian type helmets with solid crests (intricately decorated), domed helmets and Sarmatian helmets. They fought with spears, javelins, falces, and one-sided battle axes, and used "Draco" carnyxes as standards. Most used only shields as a form of defense. Cavalry would be armed with a spear, a long La Tène sword and an oval shield; few in number, they relied heavily on Sarmatian allies for their mounted arm.

Most of the infantry would wield a falx and perhaps a sica and would wear no armor at all, even shunning shields.

Mercenaries
Dacian mercenaries were uncommon in contrast to the Thracians and the Illyrians but they could be found in the service of the Greek Diadochi and of the Romans.

Nobility
A 2nd century chieftain would wear a bronze Phrygian type helmet, a corselet of iron scale armor, an oval wooden shield with motifs and wield a sword.

Navy
The ancient historian Ptolemy mentions a naval battle between the Geto-Dacians and the Romans near the island of Eukon (most likely today's Popina Island).

Fortifications
Dacians had built fortresses all around Dacia with most of them being on the Danube. A scene from Trajan's column shows Romans attacking a Dacian fortification using the "testudo".

The Dacians constructed stone strongholds, davas, in the Carpathian Mountains in order to protect their capital Sarmizegetusa. The fortifications were built on a system of circular belts. This allowed the defenders, after a stronghold was lost, to retreat to the next one using hidden escape gates. Advanced defensive systems adopted from the Greeks made their already powerful strongholds extremely difficult obstacles.

Scythian and Sarmatian
The Dacian Draco was the standard of the ancient Dacian military. It served as a standard for the Dacians of the La Tène period and its origin must clearly be sought in the art of Asia Minor sometime during the second millennium BC.

Sarmatians were part of the Dacian army as allies.The Roxolani became part of the Dacians while the Iazyges fought against them trying to claim their own land.

The Celts played a very active role in Dacia as enemies that were easily defeated by Dacians. The Scordisci were among the defeated Celts that the Dacians conquered.

Greek/Hellenic
Cothelas had become a vassal to ancient Macedon. Some Kings of the Getae had been Hellenized The Dacians traded with the Hellenistic world based upon their mineral reserves and gained better technological and cultural strategies than their Germanic and Celtic neighbours. Advanced defensive systems made their already powerful strongholds extremely difficult obstacles.

Roman


After their defeat, the Dacians were ethnically cleansed. Young men were either killed or became slaves or legionaries. The remaining population was expelled and their lands were given to colonists. Later, the Romans started minting a coin called Dacicus was minted by Domitian.

Barbarians
Dacians were spoken of by Trajan as dignified barbarians consequently still dangerous, but unable to win against the might of Rome. 1st century BC poet Horace writes of them in one of his works and mentions them along with the Scythians  as tyrants and fierce barbarians. Later historian Tacitus writes  that they are a people that can never be trusted.

The Ancient Greeks expressed admiration and respect for Burebista.
