In this history documentary we bring to life the insane scale of a Roman Army on the March! We begin with the basic marching rates for individual soldiers to establish a baseline for our analysis. We then calculate the true size of a Roman Army made up of four legions and its auxiliaries. These are then placed four men across and arranged end to end to calculate their maximum length of over 25 kilometers. However this is just part of the story.
We then cover the logistics of actually moving a force of this size from point A to point B. This is done by simulating a 24 hour cycle of a Roman army on the march. The result is a stunning 3D rendering in Unreal Engine 5 of what such a monstrously large force would have looked like. This hopefully gives you a better appreciation for the mechanics of ancient armies and how disasters such as the Battle of Teutoburg Forest could have unfolded.

Just like Rome Total War was for its time when it released.

[@hanskrieger4299]

They just wanted to make money. People wanted an arcade experience and have little historical knowledge. That's why Rome's TW put the egyptians of the bronze age. Too much realism isn't fun, unless you are a hard core fan, then it's a blessing.

[@rumplstiltztinkerstein]

@@hanskrieger4299I agree. But Total War has been going a bit stale in the last decade. I'm just saying that they should spice things up with some realism. Total War Warhammer used fantasy to the fullest. The historical games could use realism to make themselves stand out from the fantasy games.

[@hedgehog3180]

I think a lot of game devs worry that adding mechanics that aren't action focused like logistics will bore players but honestly some of the most fun I've ever had were in war games that had some sort of logistics focus like Factorio and the Anno series. It felt so much more satisfying to use a weapon in those games when you first had to go through all the struggles of setting up production lines and then supplying it. Like automating the production and supply for railway artillery and having an automated system for creating bases in Factorio makes the experience of using them feel so much better, being able to finally rain down doom on anyone at the click of a button is awesome. And in Anno 1800 finally putting your first ironclad into the water and sending it after the pirates is fucking awesome after they've been harassing your supply lines for the entire game and you having to send escorts everywhere and build harbor defenses.

A Roman "pace" was twice the length you mentioned. Romans measured it from the heel of one foot to the heel of where that same foot falls after a complete step. This is a "double-pace" in modern parlance.

[@patrickmcelroy5341]

I walked the Appalachian Trail from Georgia to Maine, 2200 miles. The average person cannot maintain 20 miles/day in that terrain. Maybe on a road that would be possible. As I walked the AT, I often thought about how fast ancient armies could have moved. Portions of the Appalachian Trail are flat or hilly and are not mountains. I'm well above average in physical fitness and I can comfortably do 20 miles/day in rough terrain for about a week before I need to slow down. If I pushed the pace I would be happy with 3 miles per hour on trail. On a road, at a solid walking pace, with a pack, I would do 4-5 miles per hour. I think moving an army through normal terrain without roads you could probably move about 12-15 miles per day. I'm sure they followed valleys and rivers to move the fastest they could, avoiding going over mountains or through rough terrain. I was also a Captain in the US Army and marching a company of 100 men long distances you have to remember that you move as fast as your slowest man. If you had to move 100 miles I would plan for 10 days. This is with modern equipment, modern boots, modern clothing and packs. In ancient times I imagine you'd have serious problems supplying enough footwear. On the AT I went through 5 pairs of modern trail running shoes. The heavier you are the more shoes you go through. It's astonishing what these roman armies had to go through.

[@68Tboy]

@patrickmcelroy5341 I've got a similar background and agree. The one thing I thought about this video was these guys were in the field all the time. They must have gotten very good at certain reoccurring issues. Like traffic jams, the slinky effect, making a wrong turn (or avoiding it), sending scouts out, heat casualties, etc. I would have loved to see how they navigated and communicated without the technology we enjoy today.

[@AldousHuxley7]

Wow 20 miles a day for a week is insane! I backpack too but can only do 15 miles in rough terrain for a week max. Probably closer to 6 days. The blisters sore muscles back joints knees feet toes take me days to heal. Those poor romans wearing cork sandals or whatever with metal gear would have been an astonishing feat. Heard some figures it was about 60+ lbs.

[@kristupassepkus1073]

I am a tour guide, so I usually do around 10 miles per day during the high season in my country (roughly 5 months). That includes all the slow pacing and loud talking during short stops (not exactly a break to rest for me). I never learned to drive and use a bus only every second day, so I rarely move not on my own feet. I was really surprised that the oldest guests usually have much more stamina than young people, who get tired after an hour and start whining. The elderly can do 2 - 3 hours without any problem and I had quite a few 80 - 90 year olds (both men and women) who nearly outdid me with continuous 6 hour tours without a lunch break. I found it strange that US soldier groups whom I was guiding around gave up pretty early. I asked them once "How come you get tired of walking so fast - you do not even have any gear on you ?" The answer was "They drive us around all the time, we barely walk". This might be a warning sign for the future...

[@patrickmcelroy5341]

@@kristupassepkus1073 Where are you doing these tours? Certain military installations have certain units that may or may not be mounted. The Army has Heavy Brigades, Light Brigades, and Stryker Brigades. So if you are near Ft Hood, TX or Ft Carson, Co, then yes those are Heavy Brigade areas so they mostly ride around on vehicles. Even the infantry in Heavy Brigades ride on Bradleys. In Stryker Brigades like at Ft Lewis, WA or Scoffield Barracks, HI those soldiers mostly ride on Stryker vehicles, even the infantry. But if you are near Ft Bragg or Ft Drum or Ft Campbell then those are Light Brigades so there are more light infantry. Ground pounders. They do more walking. Although those infantry units also have trucks and HMMWVs. They still train a lot on foot. I was in Heavy Brigades my entire time in service but I just like to hike/walk so I had no problem on the Appalachian trail. I loved it. The first month or so everyone I saw, including the most in-shape hikers, were sore. Because you are hiking every single day from sun up to sun down. It takes a while for your body to adjust to that. I did build up to the point where I could physically do 20 miles per day pretty consistently. But after about a week you just want to slow down. You can't really enjoy the beauty of the trail if you are just pushing miles all day. The Romans were probably doing much less just because the weight of the equipment and the quality of the shoes aren't as good as modern shoes.

[@babysealsareyummy]

That would've been incredible to see in person. If they ever did a reenactment of a full scale march, I'd join up in a heartbeat. Probably a pipe dream though, I can't even imagine how difficult it would be to; a: Get that many dedicated people b: Find a suitable modern trail that would be long enough to sustain that many people

[@winterroadspokenword4681]

It could be done on country roads somewhere...but have you ever taken part in a demonstration march for a cause? This will give you a sense of this movement of a mass of people. I was part of a group of a few thousand people that marched up onto dartmoor, England to protest a local landowner wishing to revoke rights to roam and camp on historically open (permissively) land. Its was very interesting indeed to see that, and how we all amassed at the end on the moor was great!

It boggles me how just about every large ancient army had to do a simular thing to this.

You could imagine that medevial crusader armies were just as complex.

[@dan_the_dj]

It makes you realize the benefit and absolute nightmare that is to face a mounted horde! Theyre all mounted and carry everything there is to carry on horses and mules. Compared to a 'regular' army, they must be soo much easier to maneuver around the place. They obviously had downsides too, but in general, its easier to harass the enemy into submission while costing you very little in the process.

[@BoarhideGaming]

@@dan_the_dj I’m sure when manoeuvring, an entirely mounted army will be a bit less tricky, but staying put for a while? Infantry can be supplied by riders and foragers for a good long while, but an army of 240 000 men means probably around half a million to a million horses. Which means if you stay anywhere for a few days, you’ll have to ride for a long while out of camp to find any grass. It’s a lot easier to transport human food than the copious volumes of grass that horses consume. And many small, spread-out bands are a lot more vulnerable, especially if the enemy is also made up of mounted troops.

[@hedgehog3180]

Crusader armies were a bit more of a motley assortment that got where they wanted to through luck or an enormous amount of help from the Romans who just wanted them out of their lands. You can see why they thought God was on their side because it's genuinely a miracle that they ever got anywhere, and most of the time they didn't.

Horseback messengers with notes. A lot of people think the linear battle of that time (shoulder-to-shoulder firing lines advancing slowly at one another) was idiotic but historians point out it was necessary to maintain communication between units. All you had to do was get the message to the commander and it would be passed through the lines man to man. Can't really do that if your units are spread out into pockets like we see in later wars with radio.

What really strikes me is how they managed to find a proper site to camp every day. It takes a massive clearing to host such a population for the night. Was their route and camp sites mapped beforehand? I'm sure that was the case for provinces close to Rome, but what happened when they ventured for months into barbarian territories, with no roads and little knowledge of the landscape?

[@Mjp11111]

Im guessing they sent scouts ahead and even if they find somewhere slightly lacking, they could send some people to clear some trees?

[@mikes9781]

The whole camp creation and management is hard to grasp. Even if there are 10,000 men to build a camp, there are too many details to just "let the men figure it out". The area for the campers, the pasturage for the animals, sanitation and water availability is staggering. . . Laying out a marching camp had guide lines, but, a legion would have to deforest several Km on both sides of a march route, if timber palisades were needed. Plus fire wood for cooking. . . If you've ever been to a Habitat for Humanity site, 6 or 7 experts are trying to control 20-30 non experts. Truth be told, the 7 experts could do the job in 4 or 5 days, with less effort, than a 2 day/30 person event. I'm not denigrating H4H, but if you've ever been to one, it's a bit like herding cats. Now, multiply that by 2000.

[@jasonl8326]

This type of movement may seem tedious and monotonous to some, but having a relatively predictable schedule for the average soldier in the field is good for morale. When a soldier knows when he'll be able to rest and eat he'll be able to better cope with the physical strain and mental boredom of the daily march. Also, breaking down and setting up camp (essentially a small fortified city) on a daily basis improves unit cohesiveness and coordination (which is absolutely vital for a successful army).

[@annunakim525]

europe is 5000 kilometres long in a straight line from Egypt to Britain at 20km a day that would be 250 days to march a legion from one end of the empire to another end. thats 8 months of marching so a legion could theoretically arrive within a year from egypt to britain (not counting the ship travel time)

The Imperial legionairs after the Marius reforms had to carry their own stuff, tents, cooking pots etc thus vastly improving their mobility. This detail i miss in this video.

[@jessgatt5441]

I have often wondered how the movement of an entire Roman Legionary army was choreographed, there is little wonder that, when the Romans faced off with an opponent they would, under any conceivable scenario, arrive fed, armed in all ways, and systematically prepared for any form of engagement, as so many defeated enemies of the Empire lived and died discovering.

Great video! The only thing I would point out is that it's highly unlikely a military unit the size of a legion would ever be able to maintain 100% of its nominal size (especially once a campaign started and men started dying off from disease and combat).

[@ryanapps903]

Really gives a different perspective to "hitting an army while strung out on the march." Like obviously I understood the benefits of attacking while your enemy is unprepared, but this really shows how forces like that in Teutoburg Forest were able to completely isolate sections of the Roman column and destroy them in detail.

[@talamioros]

When I was a teen I drew an entire Roman legion on sheets of paper aide by side, one dot at a time, to get a sense of the sheer scale, based on Gary Brueggerman's writings. I printed it all out into a small book and still have it today. How amazing technology is these days bahaha, and how pleasing it is that that reference is still current today.

[@thabomuso2575]

This was an absolutely fantastic video and I see myself qiute picky when it comes to history documentaries. The graphic and narrations was as good as always, but the way this topic was presented was the best thing. Lots of important details but they were all put in context. It seems as though under normal peacetime conditions, a larger army spent about 2 hours to break camp, 4 hours marching and 2 hours to build a capm. A full modern workday, but prior to breaking camp comes breakfast. Dinner came when the camp was established. I would like to know whether if the soldiers had lunch. Did they take breaks for toilet? How did they deal with wounded personell and animals? Also how did the conditions of the marching vary depending on the size of the armies and whether they marched during war or peace? Local foraging surelh couldn't bave been enough to supply the army in the long run. How were supplies transported from the home bases? A fantastic introduction but I have so many more quetstions.

[@thomaspinney4020]

Brilliant. Although I have studied military history for many years this graphic display made clear what I could only imagine before. As a retired military officer I fully understand both the organization, effort, and comfortable monotony such movement entails. Again, well done.

[@ROBERTN-ut2il]

I was taught in Command and Staff College that the average speed of a modern infantry unit on decent roads is 2.5 miles per hour. You can assume a march of 8 hours and 20 miles per day without wearing out the troops, although every several days, you will have to give a rest day.

[@max56562]

This was very informative and well presented , the snake visual was particularly helpful. I was also hoping for more information on how the legions were supplied , where and how livestock , weapons , food , bedding , uniforms and men were acquired. And how the supplies were compiled stored and shipped to legions in the field .

It's possible that some elements may have doubled out of the camp. They could be deployed on the line of march, with correct spacings, a lot faster than the times shown here. Jogging - or even running - out of camp would also have woken the troops up and switched them on for the day's march.

[@calj6148]

Gaul and Germania must've been the Vietnam for the Romans, tribesmen in the forest distracting the front of the column and a bigger force attacking the middle to separate the ends and the rest plundering the baggage in the rear. It just goes to show how competent a leader Caesar was as he faced this exact scenario several times everywhere he went throughout Gaul, Germania, and Britain. One specific example I recall from Historia Civillis was a close call, Caesar rallied the vanguard to hold the enemy back until the scouts and cavalry returned to harass and threaten their own counter encirclement actually fighting hand to hand himself. The Gauls realized the situation was untenable as they had lost the initiative and more of the legion would reinforce as time went on until they themselves would be outnumbered. The Gauls gave up and withdrew to fight another day but the men already raiding the baggage either in because of greed or the chaos of battle didn't hear their kinsmens call to disengage and were vengefully set upon by the Roman rearguard and dispatched. Caesar displayed a patient ability to keep calm in unfavorable circumstances and also his even more valuable skill of spotting talent when picking equally competent sub commanders which saved the army's ass on many occasions such as this.

Hence the foragers. Every day, to hunt small game to supplement the animals they brought with them. But I think each camp location would have been chosen to include a source of water as well. I guess they were pretty good at it because they did this for hundreds of years.

[@jason4275]

I would love a strategic game that took this into consideration and showed it. There are so many that have interesting C&C, but they dumb it down by subsuming the logistics behind the scenes. Something that would also include the camp followers and livestock/logistical lines. I'm someone who would love to deep dive this kind of game. You could even simplify it for general consumption by making commanders who will basically make it like other games, with the exception that you can opt to take command of these through the game settings.

[@afriendlycadian9857]

I found that the game grand tactician civil war which is a American civil war game did this quite well you armies on the map aren't just one army it's divides into corps that you can move separately down different routes etc and have a supply system one for food, ammunition and condition of your troops so you have men who are injured, ill or if morale is low they deserted for campaigns you can build forts and supply depots and garrison them etc and this is for each corps which in battle are also divided into sub commanders if you turn on realistic mode have to stay in range of the general staff to receive orders and that they can be delayed. A very good game the ai is a bit funky sometimes

Wow! Many thanks for the hard work and efforts to provide thoughtful and well explained and graphic details of the Roman army logistics. I can see some possible logistic topic suggestions - First, how the army built a new camp (walls and ditches) within less than one day. Did they bring the timber with them? Cut new trees? Both? Did each camp site have walls and ditches, especially if the legions had to march long distances, say from Italy to Britain, or Italy to Syria? Second, what about the procedure(s) where armies had to march across rivers/marshes? Did they have to send surveyors/engineers/soldiers several days in advance to build those structures, or stop at the river, build the structure, then continue the march? Overall, the sheer size, scale, calculations, and other logistics of 'moving a city' were just another impressive feature of the Roman culture which once again demonstrates the Mos Maiorum of Fides, Pietas, Religio, Cultus, Disciplina, Gravitas, Constantia, Virtus, Dignitas, Auctoritas. One more topic suggestion would be the logistics and how it might have contributed, or could have prevented, the Teutoburg Forest battle disaster. Again, well done!

[@johnpowell9174]

Nice work! Regarding pace, the rate you quote looks correct if marching on the flat. However, if there were significant elevation, progress would be slower. Naismith's rule - an extra 10 minutes for every 100 metres of ascent and of course, if in close formation, those following but still on the flat would be slowed down.

We need a full 1 hour long vid of the Dacian wars, from the 90s to 100s AD... and Trajan's later campaigns, building projects in Rome and legacy leading up to Hadrian's own with his wall & other projects till post 140s apart from the just wars.

Medieval European armies on the march and how it all worked from early to late eras with different countries across Europe. Mongol army on the march & how it all worked... the maximum size of their army was 200,000 strong = 100,000 Mongolian horse archers, and 100,000 foreign auxiliaries. Ancient & medieval Chinese armies on the march, with all their equipment & weapons of their different times... even more insane than Trajan's own armies = China's at 1 million plus strong at times... no joke there! Japanese Samurai armies on the march & how it all worked back then = 700s to 1630s AD... before the isolation era caused their decline afterwards. Persian armies of the early era against Greece, to later Parthians and Sassanid armies on the march, and how they all worked with their own different equipment & weapons.

Speaking on Roman armies logistics. . . I was throughly amused by a 1980s TV docudrama about the Roman siege of Masada. They (a Peter O'Toole film) had the Romans starving and dying of thrist in the desert; it was just plain silly. Today, Masada is just a 45-minute drive, or a 24-hour Google walk from the center of Jerusalem. Never mind the villages that were closer/in-between. Let's just go with Jerusalem. We are suspose to belief that an empire that stretched from Damascus to the Pillars of Hercules, and from Scotland to the Upper Nile, was unable to supply a garrison of only one-half legion, a mere two day's march from Jerusalem? I suspect this short makes the Roman starvation story obviously wrong. The road to Masada was probably populated with many pedestrians and shops hawking goods. They were likely moving daily mail back and forth to Jerusalem. Food and fuel were probably abundant. Plus, they were feeding two separate camps of Jewish labors as well. But today the Isreali's have this problem, they have a tourist trap out in the desert (Masada), and it's history is actually kinda boring, so they just made up a story. It was a minor side show for Rome, affected mainly by Jew POVs and free Jews working for salary. Much of the story they (Israel) try to tie to the fort (Masada) did actually occur during the civil wars, but it was during Vespasian's siege and occupation of Jodapatha. About the mass suicide: The real heroes of Israel laid dead, fighting the Romans, on the steps of the temple in Jerusalem, not hiding in Masada. The renegade Zealots who hid in Masada were the cowards who ran from the fight, having first been an early cause of the Civil Wars. For a Greek hoplite to commit suicide to avoid surrender to an enemy, was actually viewed as an act of weakness and cowardice. Not a heroic act, but one by troops too frightened of retribution for their actions/defeat.
