Originally posted by zraver View PostBased on the information provided by 79, the Romans have 3360 archers in the Levant and 480 allied horse archers. We don't know the time of that though.
The horse archers by Antoninus Pius.
Overall Augustus seams to have raised 5 archers cohorts, 13 cavalry (1 horse archers), 11 infantry (some of them with a cavalry component).
EDIT: some of the existing auxiliary units were probably formed also by Augustus , but without solid evidence, there is no way to be sure which.Last edited by 1979; 12 Jan 11,, 18:21.J'ai en marre.

Another thing to consider, is the fact that it was held half a arms length from the body armor. A missile projectile has to penetrate 3 areas of different density to reach the torso suffering increased deceleration as it goes.
Without going into the math, (weight of the arrow, initial speed, deceleration, arrow tip area and density) needed to penetrate the shield,space between the shield and lorica and ultimately the lorica ( although I did some empirical calculations) I'm going with point blank range.
Debilitating damage to shins and arms could be done outside the pilum effective range as far as i can tell.
Btw if you want a 75 % archers army , it's fine with me. :)Last edited by 1979; 12 Jan 11,, 10:50.J'ai en marre.

Then you have to game out the movement of various legions and reserves from around the Empire to the point of attack. But again this is a balancing act. I don't think the Romans could strip their borders (especially the north) bare of units because to do so invites wholesale incursions by various barbarian alliances deep into the Empire. You can raise militias/call in veterans to at least partially replace "professional" units but this will take time and any such delay would need to be estimated and included in the scenario. You also have to estimate the possibility/probability of the Romans recruiting various allies and/neutral parties to their cause. Choose the period and then choose the allies and the size/type of contribution they make - plus how long they take to arrive - more complications.
Defending the Sinai/Nile Delta and abandoning the rest of the Eastern Empire also has to be considered as an option however. Losing Egypt and its grain harvests would be a severe blow to Rome. The desirability of defending the passes/approaches to Anatolia also needs to be considered since (correct me if I'm wrong) the terrain on this "front" would suit a Roman army deployed defensivly far more than it would suit a Mongol Army. This strategy would therefore see the Romans dividing their forces along two fronts and attempting to simply "contain" the Mongols until they have pillaged the rest of the East and decide to move on (or settle down and stay - their choice).
Whatever the "Roman side" decides to do as noted previously the biggest problem the Romans face will be the sheer size of any invading Mongol army - unless you deliberately decide the minimize the likely size/scope of the invasion. There are a hell of a lot of variables to include before you could hope to get valid outcomes.Last edited by Monash; 12 Jan 11,, 13:56.If you are emotionally invested in 'believing' something is true you have lost the ability to tell if it is true.

The Romans also have the option of leaving strong garrisons in at least some major inland cities in the hope that the Mongols can be at least be partly delayed/hurt taking them - maybe the Mongols would oblige, maybe they would simply bypass any strong points along their lines of advance. But this requires a careful balancing act, leave too many units in garrison and you end up with no manoeuvre force of any significance and your troops scattered accross the "board". So on balance I would favour pulling most if not all units back to the coast and leaving the inland cities to fend for themselves.
With a emperor like Lucius Verus, a relief force might also take time to arrive.

if slightly inferior in numbers, we can avoid the enemy;
if quite unequal in every way, we can flee from him.

I'll address the other point you have raised ( about balancing reinforcements ) at a latter time .J'ai en marre.

I say the Mongols would win easily because Romans are no match for the quick cavalry of the mongols. The slow-moving and heavily armored Roman soldiers would be destroyed by the Mongols.
The Mongols were known to use gunpowder, and grenades and their methods of seige warfare would equal if not surpass the Romans.
The Romans would be clearly overwhelmed.

Using rather rough time frames 30BC-70AD The area of the Levant and surronding areas had 11 legions. Thats somewhere between 90-160,000 Imperial troops. During the jewish Revolt Herod Agrippa and loyal towns added 40,000 troops not counting garrisons. Assuming similar numbers of local troops per region (Syria, Judea, Anatolia, Egypt). The maximum Roman force not counting bar eminimum garrisons is 160,000 Imperial troops and 200,000 locals.
Judea- X Fretensis, VI Ferrata, III Gallica
Armenia- I Parthica,
Anatolia- XVI Flavia Firma, IV Scythica
Egypt- III Cyrenica. XXII Deiotarina
Syria- XXIV Othion Rapax, III Galicia, and VI Ferata

The Roman legions: general introduction
I Parthica
This army unit and its sisters II Parthica and III Parthica were founded in 197 by the emperor Lucius Septimius Severus, who used them in his war against the Parthian empire.
The former legion XVI Gallica, which had been disgraced by its conduct during the Batavian revolt (69-70), was reconstituted by the emperor Vespasian under the name XVI Flavia Firma (Cassius Dio, Roman Histories, 55.24.3) and transferred to the eastern provinces. This transfer was some sort of punishment, because the soldiers of XVI Gallica were from Gaul in the west. Yet the men must have been happy that they were not dishonorably discharged.
???
IV Scythia
Between 6 and 9 CE, IIII Scythica was active in the wars of Tiberius (the future emperor) against the Illyrians and Pannonians on the Middle Danube. Fighting was not the only activity of the legion. Several rock inscriptions prove the construction of roads and other works of engineering in the Danube area. The newly conquered country needed to be developed. Usually, IIII Scythica joined forces with V Macedonica. Among those who served in the legion was a young man named Titus Flavius Vespasianus, who is better known as the emperor Vespasian.
During the reign of Nero, the legion was transferred to the east.Last edited by 1979; 15 Jan 11,, 14:10.J'ai en marre.

Sorry about I Parthica
Depending on time there might be as many as 50 legions worth of trained troops available. If word of the Mongol advance reached Octavian in 30 BC just after the death of Antony there near 40 legions in the East.

50 legions worth of troops equals about 1.8 % out of 15 million roman citizens, ( using your figures because i don't have a reference at hand ).
They can certainly mobilize equip and train that many citizen soldiers during a crisis, but I'm not sure they are willing keep such a large standing army during peace time.
28 legions at the time of the Teoutoburg forest battle is 0.9 %, sustainable percentage even by today standards. Also the transformation of the auxiliary formations into standing units relieved some pressure from the roman citizens, without diminishing the total number of troops available.
Increasing the service length to 25 years means that each year the roman citizens have to provide only ~ 3.000 replacements for the discharged veterans. The draft standards could be increased accordingly (fewer replacements means you could afford choose only the best ), for the auxilia the standards would be even higher.
Overall Augustus seems to be a wiser leader than those who come before him.Last edited by 1979; 16 Jan 11,, 13:50.J'ai en marre.

He could afford to be that wise.No more major wars.Even Teutoberg was nothing compared to Arausio .
Roman numbers are meaningless.We are assuming the Mongols just fell from the sky on their border.But in any case,the Mongols just cannot jump directly on the Romans-they cannot achieve 100% strategic surprise.The result of any major crisis in Parthia is that Roman armies would be increased in number,both by reinforcements and by raising local troops.
About the Sinai defense,it's feasible,but only after the rest of the Levant is lost.Then it depends on how many Roman troops are left.35-40000 are probably the upper limit anyway,from a logistic pov. They need to drink(a lot I may add).Those who know don't speak

compared to the Mongols that is drop in the bucket , a horse drinks 20 times as much as a human , and the Mongols have more than just a horse.
15 millions?? I suppose you include women and children,but IIRC the number of citizens during Augustus was no more than 4-4.5 millions (men and women).The number of citizens during Augustus rose slowly,mainly due to auxiliaries ending their military service.Up until Caracalla the citizens number was never more than 10%.Those who know don't speak
