(In which Tim maps the Roman Empire in the first century AD through five battles)

“Varus, give me back my legions!”

So the ageing Emperor Augustus is said to have shouted, driven mad by the loss of three legions at The Battle of The Teutoberg Forest in AD 9. Quinctilus Varus was the Roman commander who led those legions into the dark German forests, never to return. This is the first battle of the first century. Rome’s devastating response following the campaigns of the aptly named Germanicus shall be my next focus as exemplified by The Battle of Idistaviso in AD 16.

The invasion of Britain under the Emperor Claudius in AD 43 merits a mention. As does the defeat of Boudicca at the Battle of Watling Street in AD 61 where Rome firmly put down her revolt. The Battle of Mons Graupius in AD 83 finally consolidated Britain (minus Caledonia) into the Empire.

The siege and destruction of Jerusalem in AD 70 is an obvious landmark battle. The Jewish revolt was a major uprising and occurred during one of the few periods of outside instability the Roman Empire faced in the first century. Its impact is probably still felt today.

Whilst Titus was dealing with the Jewish revolt, his father Vespasian had marched on Rome to throw his laurel wreath into the ring to become Emperor. The ‘Year of the Four Emperors’ in AD 69 was the first Roman civil war in 100 years. Previously Emperors had just been assassinated, poisoned or committed suicide. This violent transfer of power though was limited to the unfortunate Emperor and his immediate supporters and didn’t lead to a full-scale civil war as had been the norm in the late Republic. Although, Rome soon came back to normalcy - and indeed the Emperors improved - this respite would be only temporary and civil wars would come back in a big way towards the end of the second century.

A note on the army itself: The Roman army of the 1st Century AD looked exactly like the Roman Army in popular imagination. They wore curved helmets protecting the back of their necks, segmented armour, carried long curved rectangular shields, held short thrusting swords and threw devastating volleys of weighted spears. A legion consisted around 5120 men divided into 10 cohorts (the 1st being double sized). There were 28 legions in Augustus’ time, later increased to 30. Auxiliaries assisted the legions (archers, calvary, skirmishers etc) and their number was around the same. Therefore, a reasonable assessment of the size of the Roman Army of this period is 300,000 men under arms.

The first century began with Augustus in the 28th year of his principate. Unlike much of the previous century, The Roman world was pretty much at peace with itself. The civil wars were over. Augustus stealthily added nations that were protectorates - like Egypt - to the Empire avoiding outright conquering. However, his sons-in-law - Drusus and Tiberius - added Raetia (modern Switzerland). But this Caesar - unlike his famous uncle - was content to be imperator in name if not in deed.

However, one recurring trouble spot in the Empire was the Germanic tribes beyond Gaul. Could Augustus add Germania to the Empire and, if not, where was the defensive line of the empire to be drawn? It was going to be the river Elbe but - following the loss of the legions in the forests - Rome pulled back to the Rhine where it stayed for the next four hundred years.

The Battle of the Teutoburg Forest was the shock that caused this retrenchment. Three legions (plus assorted auxiliaries and camp followers) operating beyond the Rhine, were betrayed by a supposed friendly German ally, Arminius, and massacred. Arminius led Varus into the dense forest and then sprang his trap. The army was wiped out and their totemic eagles taken.

At this point in time, Rome had just 28 legions. The loss of three meant a sizeable chunk of the available forces had just disappeared. No wonder Augustus was upset. Revenge came slowly and - as was the wont at these times - through a member of the Imperial family.

Germanicus was nephew to the new Emperor Tiberius and was sent to the Rhine to sort out the mess left after Arminius’ triumph. Fighting many battles and chasing many tribes into many forests, Germanicus skirmished and harassed the Germans time after time over three years until he finally tempted them into an open pitched battle. This was at the Weser River and became the Battle of Idistaviso AD 16. The result was a massacre of the German tribes. Arminius survived only to be beaten again that same year at The Battle of the Angrivarian Wall. (He was later killed by members of his own tribe. He is still celebrated as one of the founders of the German nation. His massive 19th has century statue stands above the Teutoburg Forest to this day.)

Rome had won the conflict but Tiberius, ever cautious, withdrew Germanicus to Rome and the Empire’s frontier was settled back at the Rhine.

Julius Caesar had come across the Channel to Britain a couple of times but he never made a serious invasion attempt - he was too busy conquering Gaul. These incursions provoked a few fights, garnered some tributes and alliances, but Caesar didn’t stick around to conquer Britain. One hundred years later though, in AD 43, the unwarlike Emperor Claudius - another nephew of Tiberius - launched the invasion of Britain.

The conquest was a slow process taking over 40 years. The south of the country was relatively passive, having interacted with the Romans for years. However, the North and West and Wales proved much more difficult. Whilst the Romans were distracted subduing the Welsh tribes in AD 60, the Iceni under Boudicca rebelled back in the conquered south. The rebellion was short, violent with the rebels burning and massacring the Roman towns of St Albans, Colchester and a little town called Londinium.

The governor, Seutonius Paulinus, gathered up a force centred around one and a half legions and met Boudicca and her army somewhere along what became known later as Watling Street. He chose his battlefield well, funnelling the Britons into a narrow front. As had happened many times previously in Roman history, well-trained legions overcame a larger but undisciplined horde. The rebels were massacred - hemmed in by their own carriages - and Boudicca committed suicide not long after.

Twenty of so years later, the Romans had turned their attention to the north of Britain. Up in Scotland, the Caledonian tribes were causing problems. However, the usual rules applied; tracking a tribe into an open pitched battle was difficult and whilst traipsing around the wet and cold of Scotland, the Roman army was prey to ambushes and lightning strikes. Governor Agricola finally lured the Caledonians into battle somewhere in the mountains of Scotland (the precise site is unknown). The Battle of Mons Graupius AD 83 was unique in that the Romans won it using only their highly trained Germans auxiliaries with assistance from the cavalry.

Tacitus, who wrote the account of the battle, famously put words into mouth of the Caledonian leader, Calgacus, “They make a desolation and call it peace.” All Britain was conquered. For now.

Back a few years, and we have the brutal Siege of Jerusalem in AD 70 part of the First Jewish-Roman war. Pompey had added Judea to the empire back in the Republican days. He’d even successfully laid siege to Jerusalem. This time though, the struggle was more bitter as a hardcore sect of rebels within the city - the Zealots - refused to surrender. As Vespasian had left for Rome, his son Titus (later emperor too) led the four legion assault on the city. Starvation, disease and the terrors of war were meted out to the inhabitants of the city, bolstered as they were by hundreds of thousands of refugees escaping the wider war. The end was a massacre:-

“They poured into the street sword in hand, slaughtering indiscriminately all they came across and burning houses with those who had fled there still inside… Since the troops had run out of victims to kill or property to loot, Caesar ordered the army to raze to the ground the whole city and the temple…” Josephus, The Jewish War (Book 6:404 / Book 7:1)

Jerusalem and its population was destroyed. This was quite a consequential siege in history.
