Wars of Augustus

The wars of Augustus are the military campaigns undertaken by the Roman government during the sole rule of the founder-emperor Augustus (30 BC – AD 14). This was a period of 45 years when almost every year saw major campaigning, in some cases on a scale comparable to the Second Punic War (218–201 BC), when Roman manpower resources were stretched to the limit. This period also saw expansion through diplomacy and annexation, without the direct use of military force. The result was a major expansion of the empire that Augustus inherited from the Roman Republic, although the attempted conquest of Germania ended in defeat despite the enormous deployment of resources involved. As a result of these campaigns, the Roman Empire assumed the borders it would hold, with a few modifications, for its entire history.

Overview

In 29 BC, the Roman Senate ordered the closure of the doors to the Temple of Janus in the Roman Forum for the first time in over 200 years. Signifying that the Roman state was no longer at war, this act reportedly pleased Augustus, then in his 5th Consulship, more than all the other honours showered on him. This allowed him to continue perpetuating the image of himself as the bringer of peace he had earned after ending the civil wars of the previous several years. But the closure could not have been less appropriate. As Dio himself points out, there were ongoing major operations against the Treveri in Gaul, and the Cantabri and Astures in Spain. Furthermore, the closure inaugurated nearly half a century of virtually incessant warfare, during which Augustus dramatically enlarged the Empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia, expanding possessions in Africa, and completing the conquest of Hispania, but suffered a major setback in Germania. As a result, Augustus would establish the frontiers of the empire for centuries and further instill the idea of being "world-conquerers" in the Roman people from their Mediterranean-centered views.

Chronology

30 BC

GAUL: The Morini and Treveri tribes of Gallia Comata province (Pas-de-Calais region of NE France), rebel against Roman rule and the Suebi Germans cross the Rhine to give them support. But the Morini are defeated by the proconsul (governor) of Gaul, Gaius Carrinas, who goes on to drive out the Suebi, for which he is awarded a joint Triumph with Augustus in 29 BC.

EGYPT: The ''prefectures Aegypti'' (governor of Egypt) Gaius Cornelius Gallus quells two local revolts in Heroonpolis in the Nile delta and in the Thebaid. Subsequently, he leads a Roman army South of the First Cataract of the Nile for the first time. He establishes a puppet-state called '' Triacontaschoenos'' under a local petty king to act as a buffer-zone between Egypt and Aethiopia (i.e. the kingdom of Aksum), as well as a loose protectorate over Ethiopia itself. Despite his success, Gallus incurs Augustus' displeasure by erecting monuments to himself and is recalled to Rome, tried by the Senate and convicted of various unspecified charges and banished.

29 BC

GAUL: The Treveri revolt is quelled by the new proconsul of Gaul, C. Nonius Gallus, who is rewarded with the title of ''imperator'' ("supreme commander").

LOWER DANUBE: The proconsul of Macedonia, M. Licinius Crassus, grandson of Crassus the triumvir, launches the conquest of Moesia. He chases an army of Bastarnae, which was raiding a Roman allied tribe, back over the Haemus (Balkan) mountains but fails to bring them to battle. He then marches against a major fortress held by the Moesi people. Although his vanguard is routed by a Moesi sortie, Crassus succeeds in taking the stronghold. After that, he intercepts and routs the Bastarnae host near the ''Ciabrus'' river (Tsibritsa, Bulgaria), personally killing its leader in combat. Those Bastarnae who escape across the Danube river, and entrench themselves in a natural strongpoint, he dislodges with the assistance of the local king of the Getae. Crassus then turns his attention to the Moesi again. After a long and arduous campaign, he forces the submission of the great majority of Moesi.

26 BC

SPAIN: Augustus takes personal command of the campaign against the Cantabri.CAH X 451

EGYPT: Responding to a directive from Augustus, the ''prefectures Aegypti'', Aelius Gallus (no relation to his predecessor, Cornelius Gallus) leads an expedition across the Red Sea against the Sabaeans of Arabia Felix (mod. Yemen). The key attraction was that this region produced aromatic substances such as frankincense and myrrh, which were greatly prized in Rome. In addition, occupation of Sabaea would give the Romans control of both sides of the entrance to the Red Sea, the Bab-el-Mandeb strait, since Cornelius Gallus had established a garrison at Arsinoe (near Assab, Eritrea) on the Ethiopian shore. The expedition consists of 10,000 troops including allies, and 130 freight-ships. Gallus was counting on the assistance of the Nabataean Arabs of NW Arabia, whose king Obodas was a Roman ally and contributed 1,000 warriors under his chief secretary, Syllabus. But the latter allegedly sabotaged the mission throughout with poor advice. The force sails by ship from ''Clysma'' (Suez, Egypt) to ''Luke Come'' but suffers heavy losses to storms in transit, so that on arrival, Gallus is forced to spend the rest of the year at Lake Come to give his men a chance to recuperate and to effect repairs to his fleet.

25 BC

SPAIN: Augustus, although in nominal command of the campaign against the Astures and Callaeci, is incapacitated by illness. The campaign is brought to a successful conclusion, with the last rebels crushed, by the governors of Hispania Citerior and Ulterior, respectively Gaius Antistius Vetus and Publius Carisius.

ALPS: Augustus despatches an army under Aulus Terentius Varro Murena against the Salassi tribe of the Val d'Aosta region of the northwestern Alps. The latter controlled the Great St Bernard pass, the shortest route between Italy and the Upper Rhine region. The Salassi are utterly defeated and, according to Strabo, Murena deports and sells into slavery 44,000 tribespeople.

GALATIA: King Amyntas dies, but Augustus prevents any of his sons from inheriting the kingdom, instead placing Roman governors in charge of Galatia and Lycaonia

20 BC

ASIA: Augustus reaches a settlement that establishes individual rulers of Cilicia, Emesa, Lesser Arminia, and Commagene, bringing them under Roman influence. Additionally, Tiberius invades Armenia and reinstates King Tigranes.

PARTHIA: Roman prisoners of war and captured standards are returned, and the acceptance of a more peaceful co-existence between the Romans and Parthians is established. This is praised as a "bloodless" victory and further cemented the idea in the empire of universal Roman rule being accepted.

15 BC

ALPS: Tiberius and Drusus begin to campaign throughout regions in the Alpine territories; securing land, strengthening positions, in preparation for the invasion of Germania.

Roman Campaigns in Germania (c.12 BC – AD 16)

The Roman campaigns in Germania were a series of conflicts between the Germanic tribes and the Roman Empire. Tensions between the Germanic tribes and the Romans began as early as 17 BC with '' Clades Lolliana'', where the 5th Legion under Marcus Lollius, Usipetes, and Tencteri. Augustus responded by rapidly developing military infrastructure across Gaul. His general, Nero Claudius Drusus, began building forts along the Rhine in 13 BC and launched a retaliatory campaign across the Rhine in 12 BC.

Drusus led three more campaigns against the Germanic tribes in the years 11–9 BC. For the campaign of 10 BC, he was celebrated as being the Roman who traveled farthest east into Northern Europe. Succeeding generals would continue attacking across the Rhine until AD 16, notably Publius Quinctilius Varus in AD 9, who suffered a major humiliation at Teutoburg Forest. During the return trip from his campaign, Varus was betrayed by Arminius, who was an ally of Rome and leader of the Cherusci. Roman expansion into Germania Magna stopped as a result, and all campaigns immediately after were in retaliation of the '' Clades Variana'' and to prove that Roman military might could still overcome German lands. The last general to lead Roman forces in the region during this time was Germanicus, the adoptive son of Augustus' successor, Tiberius, who in AD 16 launched the final major military expedition by Rome into Germania. The Roman Empire would launch no other major incursion into Germany until Marcus Aurelius (r. 161–180) during the Marcomannic Wars.
