The siege of Plataea early on in the Peloponnesian war 430 BC is interestingly described by Thucydides. It might be that not a single city wall was successfully stormed during that 27 years long war. The trebuchet was introduced in Europe only after the war to solve this frustration. They had only battering rams, attempts to build huge siege ramps, and pole vaulters (any volunteers? No, why?) A funny part, on building a ramp that mysteriously stops growing: "The Plataeans changed their mode of operation, and digging a mine from the town calculated their way under the mound, and began to carry off its material as before.This went on for a long while without the enemy outside finding it out, so that for all they threw on the top their mound made no progress in proportion, being carried away from beneath and constantly settling down in the vacuum."

It's like fortresses have simply grown ever bigger and more decentralised in response to increasing firepower. To the point where they are so big that they are no longer recognised as 'fortresses'. Starting with a walled settlement or castle. Spreading out into a star fortress with additional outworks. Adding more detached fortfications in front to form a polygonal fortress. When even that could be razed, fortifications stretched into trench systems long enough to bisect whole countries. Which finally turned into a 'defense in depth', dozens of kilometers deep. Whole towns now serve the purpose of 'outworks', where defenders have to be just as mobile as attackers.

WW1 was brutal though. Especially the Germans with their dedicated siege train (think railway guns or Big Bertha), just blasted apart 18th and 19th century fortresses like the cannons of the 15th and 16th century did to medieval walls. Those buildings simply could not handle being hit by early 20th century armour piercing shells. Reinforced concrete bunkers where the response, but those are also limited in their effectiveness. WW2 saw far fewer usage of siege guns, but the Germans once again had their dedicated siege train that cracked open pretty much anything. The result is that defences now are dispersed and in depth. That also was made possible by the massive increase in firepower with machine-guns, mortars, artillery, but also range finding equipment and methods to lay down extremely accurate fire. Because no single strong point can be expected to last long. The siege guns of old are gone, but they have been replaced by rockets, missiles and (guided) bombs that still are more than capable of devastating individual fixed fortifications. Thus spreading them out to prolong the ability of fortifications to resists. Because in the end, fortifications are intended to make the cost of attacking them, prohibitive. Eventually everything can fall. But the cost needs to be made as high as possible.
Oh, wow, never thought you'd cover this period but to be honest it fits well with the overall theme of the channel. Maybe continue and also cover sieges in the 20th century?
the best way to know how to breach any defense, is to be supremely good at defense. Once mastery of defensive warfare is achieved, a person now knows all teh various weaknesses of a given defense, and now knows precisely how to defeat each layer of a given defense.
This video brilliantly illustrates the evolution of siege warfare and the constant battle between offense and defense. It's fascinating to see how innovations like Vauban's methods and polygonal fortresses shaped history. The level of strategy, engineering, and ingenuity involved in these conflicts is truly mind-blowing. Great work on breaking down such a complex topic so clearl
Thank for this Video. I'm always interested in sieges and your videos are just perfect for that. If you want to make a video regarding the prussian system I would love to see cologne in it. Since I live there😅
You said polygonal forts required besiegers to come up with newer methods than Vauban's for taking the previous generation of star forts. However, what you illustrated was just the same as before with parallels and saps. And while this is true to a certain extent, it also isn't due to the VAST improvements in artillery coming thick and fast due to the Industrial Revolution. The most important changes here were to range (thanks to rifling), effectiveness of each shell (due to the invention of high explosives and armor-piercing shot and shells), rate of fire (due to breechloading cannon), and size of cannon (due to improvements in metallurgy and means of transportation). Of course, fortresses also got barbed wire, reinforced concrete, armor plating, and revolving, even retractable turrets, too. And all these innovations were adopted at different times by different nations so wars and sieges often featured different mixes of all these things on both sides. Thus, generals had to adapt quickly to new tech and quickly see how it could best be used against what the enemy happened to have at that moment. So in the days of short-range smoothbores, star forts were good because they provided fire superiority at close range. But as weapons' ranges increased (there was a brief time in the 1850s when infantry outranged artillery thanks to having rifles while the cannon were still smoothbore), decisive firefights happened at longer ranges so forts had to shift their emphasis from short-range crossfire to long-range frontal fire. This was the main reason for the change from star forts to polygonal forts. The polygonal fort tried to mass as many cannon as possible along the ramparts. And while Montlambert's caponiers were designed with massive artillery, he was still thinking in terms of the short-range crossfire of star fort days so they mostly fired across the face of the fort. The caponiers that were actually built were mostly for riflemen, revolving small-caliber artillery, and then machineguns, for a last defense of the ditch, as the issue would really be decided at long range with frontal fire from both the fort and the besiegers. But as the range and power of artillery increased, having all the fort's guns exposed on the ramparts, or even having ramparts at all, became too vulnerable. Thus, eventually, forts became almost entirely subterranean concrete boxes with only a few (often retractable) turrets above ground. They still had a ditch but the caponiers had been replaced by light batteries (revolving cannon and machineguns) at the angles of the counterscarp to fire along the ditch. That was still quite difficult to storm, so then ultra-heavy howitzers were developed to fire literal bunker-busting, battleship-caliber armor-piercing shells into the subterranean core of the fort, and steam trains and tractors could move these to the front lines. The forts had no answer to this, even though some continued to be built, such as the Maginot Line. And then airpower made all this sort of thing rather moot.
Yes. Next step was the trench, weaker than a concrete fortress, but much more resilient and, actually, almost impregnable. Next step after the next step was coming back to the hard fortress, but in a mobile arrangement, called tank.
Thank you for this. It's very clear that this video is like half cooked, like cut in half. Not just how they said methods of attackers had to be adjusted but then practically didn't explain / show anything, but also from the opposite side - the defenders. They said about that key factor was increase of firepower, caponiers, amassing canons - and here showing even pretty funny high artillery tower - but then not presenting anything how did it work, what did it change exactly. So caponiers were so crucial development, something defining polygonal forts and then it's presented that when attackers reached the line of defence they just... storm though it and it's over? Like huh? Video might seem as a nice work, but it's very poor really. It's clear just on logical and structural level. From your comment I've realized it's even much worse and thanks very much.
@@MarionFR Well, Marion. If You will have the opportunity of travelling in Italy, within a radius of 150 km around Turin (my home) You could see, and visit, twenty centuries of military architecture, from Ancient Rome to Maginot. Perhaps the best way to understand how they worked. In Turin there is, too, one of the most important Artillery Museum in Europe, collecting guns from XV to XX Century. Wellcome.
Nice comment, it's an alright overview but it seems like a remake of the video on star fortresses. I was always asking for more explanations but he quickly moved on to the next point. I think this is a subject that can't be broken down in this way, as it covers centuries of history, many wars, many fortification designs, perspectives from defenders and attackers and the wider world of fortifications and weapons.
Fort Tigné in Malta might be the earliest 'modern' polygonal fortress. It was ordered by Grand Master Emmanuel de Rohan-Polduc, and designed by the Order of Saint John' engineer Antoine Étienne de Tousard, to be finished in 1795.
The Austro-Hungarian WW1 uniform at 12:25 is incorrect as collar stripes (as opposed to full patches) would only be found on later "field grey" colored uniforms, not blue ones.
Have the better navy andlay suege or hope they are not complete then you just need cuning. Like how that Spainire commander took ranmpa florida wirth basically nothing despite everyone else thinking it was impossible even with the British navy... But because it wasn't complete it was easy just sail under the gunfire and watch the cannon balls ail safely over head... This was during tghe americain revolution by the way adn was the most underrate cluctch play pof the war.
Star and polygonal have both covering fire along the wall. Both were also open battery platforms build against direct fire at their origin, using mortars seems the best solution.
Sail close to the fort flying friendly colors, disembark your troops into boats on the seaward side, open up on the fortress at the last second and keep up the barrage to cover the landing force. When they reach the island, they need to scale the walls or breach the gates quickly, or they won't last long in such an exposed position. "L'audace, l'audace, toujour l'audace." I'm paraphrasing Cochrane's reduction of three forts in South America from memory, so please look it up and refine it before attempting.
appreciate the nod to humane warfare at the end, laying out when it was strategically sensible and therefore morally acceptable to surrender, a very valuable lesson
So house-to-house combats using suicide bombers and armed civilians are the real last line of defense, as it was at the Battle of Shanghai Warehouse with Dare To Die corp wearing civilian clothes carrying bags of grenades?
I woke up today really bothered. The realization hit me as I drank my Earl Grey tea that i had no idea how to attack a polygonal fortress in the 18th and 19th century. One can imagine my wry smile as i stumbled across this timely recommendation. You're in big trouble now Polygonal Fortresses of the 18th and 19 century. I'm coming for you.
3:11 To an extent, the tactics were similar. However, the difference lay in the fortifications that were being used by the Confederates. Rather than developing full Star Fortresses with brick construction, the Dimmock Line (the main defensive system around Petersburg) relied on a mix of trenches, batteries, and outward-facing fortifications, which acted more as oversized artillery batteries than Star Fortresses. The only fully enclosed fortification within the Petersburg and Richmond defenses was Fort Darling - located at Drewry’s Bluff - that was a five-pointed Star Fortification made entirely out of earthen material. The reason for this choice was rather simple; if the Union took the fortification, they would have virtually nothing to defend themselves against an assault from the Confederate Positions, thus making it difficult to defend their gains. Whenever the Federals captured a fortification - such as Battery No. 5 on the Dimmock line or Fort Harrison on Richmond’s Eastern Defensive Line - they would have to engineer and construct new sections of walls towards the Westward-facing sections of the fortification in order to rectify the lack of defenses along those sections. However, even when the Federals took those positions and reincorporated it into their works, the Confederates would simply build a new defensive line behind the captured position. Both Battery No 5 and Fort Harrison would see this happen with the Confederates taking up position along a new defensive line a short distance from their prior line, thus making any gains near meaningless. It’s why Grant opted to wrap his army around Petersburg and cut off the railroad and plank roads leading into the city, thus starving it and - in turn - the City of Richmond.
Two things I've noticed: 1) the role of towers: Renaissance castles had cannon towers, starforts mostly didn't but then they briefly reappeared in polygonal forts. This leaves the question if they had also observation towers or posts to spot the enemy early or organising resistance. With Starforts or polygonal forts with outposts, organising a defense must have been really difficult without telecommunication... Obviously, the lack of towers doesn't confirm their absence. Starforts were altered during wartime preparations, as some buildings were torn down and reinforcements were made. Possibly further trenches and obstacles were added as well. A wooden tower wouldn't cost much by comparison and it would be difficult to hit, unlike a solid tower... 2) How did the outposts work? Yes, they were meant to engage the enemy and withstand somewhat a siege, but they were too small to be held indefinitely and would be rather easy to encircle. Who would want to man the post, if you know that you'll be fighting to the bitter end? Alternatively, you might build an escape tunnel, but that's quite costly...
Your videos are always so well researched. Have you considered making one about more modern fortifications? Like the sere de rivieres system or evwn the maginot line?
To say medieval walls were “no match” for large cannons is an oversimplification. They certainly weren’t nearly as durable as wide bastion walls, but several meters of stone is never easy to breach, even with cannons. There are many cases of medieval fortifications sustaining siege via cannons.
I often wonder what a 'modern fortress ' would consist of. Had better artillery not made it obsolete. I'll always be that little boy building castles with LEGOS. Fantastic video as always!
By the way, the Tower of Belém in Lisbon, built finished in 1520, kind of reminds me of a cross between a tall medieval tower and a polygon fortress - that is, passing over the intermediary star phase. The three-faced water side is remarkably like a polygon.
The point of fortress, just like a current military patrol base or logistical base is not to sit inside and wait to be attacked. The point was to project power. When an Amry you could not whip began to invade you had to vacate and dismantle the fortress and begin fighting a regard action and orderly retreat to ground you can defend. Unless you are absolutely positive that a relief Army, along with your soldiers will be powerful enough to defeat your enemies. Fortresses are good for a place where your soldiers can truly rest and recover from defensive patrols and then refit and continue to conduct patrols. They were meant as a base from which to launch operations from 😊
nice to see the american civil war starting to creep in. it was as much a bridge between the old world fighting of the 18th century and a prelude to the modern fighting of the 20th century
So this video leaves me with an unanswered question: how was the polygonal fortressvmore resilient to the formal siege than the preceding star fortress? The formal siege you described here looks basically identical to one you described vs star fort in its video, and I didn't quite get from the video what new challenges were presented by the polygonal fort and how did the attackers adapt to them
There are probably several points: -The forts meant that the besiegers had to start much further out. -Riochets were much weaker (their strength against bastioned fortifications was that you could skip them along the ramparts ) -Casemates where of course much harder to surpress than open canon emplacements, meaning the defenders were much better at firing back. -More and more concentrated artillery made counter battery fire much more effective
@@TheWampam And as well, the fortification was more dispersed and disconnected, meaning there would be many batteries and earthworks to capture along to the main fort
One thing I always thought was funny was how in Empire Total war, defending the square fortress was possible with 4 units (one for each side) but defending the star fortress which was like 5x more expensive required 10 units to properly defend (two for each spoke) and because the perimeter of the fort was made exponentially longer it was much easier for an enemy to mass all his men at one spoke and overwhelm you there because it would take you forever to re-position.
@@thereynaldosan7695 No you can, the forts have built in swivel guns that will fire, BUT you need to have each face of the wall garisoned by a unit to activate them, hence the necessity for a minimum of 10 units which in the game is rather difficult and uncommon to do.
Ye I agree, I think sieges in empire were done quite horribly even though they have the potential to be really fun. The guns should've gotten deadlier with each progression and should've been manned by their own gunners. It's stupid how forts are left completely empty if you don't have a 150 man line infantry unit in there (that can only take position on one part of the wall.) It's also way to easy to approach the fort, there's no heavy artillery pieces that require progressive siegeworks. you can run up to the fort with minimal casualties and win. If they ever do another gunpowder total war they should add a separate siege system I think.
There are siege rules in the back of "Warfare in the Age of Reason" which is a set of rules for tabletop miniatures. In theory, you need model soldiers and terrain. However, it could be played with pen and paper. It just won't be nearly as pretty.
Its going to be interesting to see how seiges worked on fortifications in the 20th and 21st centuries. I dont know if your expertise is in this field but I do hope you take a crack at it.
That makes me think, any chance of you making a video on the siege of Belfort in 1870 - 1871 ? The place was reinforced by Vauban and later again during Napoleon's time, and saw many interesting aspects of late XIXth century siege warfare, including a failed relief attempt that failed only a few kilometers away from the city.

The result is that defences now are dispersed and in depth. That also was made possible by the massive increase in firepower with machine-guns, mortars, artillery, but also range finding equipment and methods to lay down extremely accurate fire. Because no single strong point can be expected to last long. The siege guns of old are gone, but they have been replaced by rockets, missiles and (guided) bombs that still are more than capable of devastating individual fixed fortifications. Thus spreading them out to prolong the ability of fortifications to resists. Because in the end, fortifications are intended to make the cost of attacking them, prohibitive. Eventually everything can fall. But the cost needs to be made as high as possible.
Oh, wow, never thought you'd cover this period but to be honest it fits well with the overall theme of the channel. Maybe continue and also cover sieges in the 20th century?

Yes TH-cam, I'm interested. I need to know how to capture a Polygonal Fortress, you never know when it will be useful.
the best way to know how to breach any defense, is to be supremely good at defense. Once mastery of defensive warfare is achieved, a person now knows all teh various weaknesses of a given defense, and now knows precisely how to defeat each layer of a given defense.
This video brilliantly illustrates the evolution of siege warfare and the constant battle between offense and defense. It's fascinating to see how innovations like Vauban's methods and polygonal fortresses shaped history. The level of strategy, engineering, and ingenuity involved in these conflicts is truly mind-blowing. Great work on breaking down such a complex topic so clearl

Amazing tutorial now I just need to know how to properly build my own polygonal fortress.
Great video I’ll keep this in mind whenever I need to lay siege to a polygonal fortress from the 18th and 19th centuries.
Thank for this Video. I'm always interested in sieges and your videos are just perfect for that. If you want to make a video regarding the prussian system I would love to see cologne in it. Since I live there😅
The time I waited for this video is immense, but so is my enthusiasm
You said polygonal forts required besiegers to come up with newer methods than Vauban's for taking the previous generation of star forts. However, what you illustrated was just the same as before with parallels and saps. And while this is true to a certain extent, it also isn't due to the VAST improvements in artillery coming thick and fast due to the Industrial Revolution. The most important changes here were to range (thanks to rifling), effectiveness of each shell (due to the invention of high explosives and armor-piercing shot and shells), rate of fire (due to breechloading cannon), and size of cannon (due to improvements in metallurgy and means of transportation). Of course, fortresses also got barbed wire, reinforced concrete, armor plating, and revolving, even retractable turrets, too. And all these innovations were adopted at different times by different nations so wars and sieges often featured different mixes of all these things on both sides. Thus, generals had to adapt quickly to new tech and quickly see how it could best be used against what the enemy happened to have at that moment. So in the days of short-range smoothbores, star forts were good because they provided fire superiority at close range. But as weapons' ranges increased (there was a brief time in the 1850s when infantry outranged artillery thanks to having rifles while the cannon were still smoothbore), decisive firefights happened at longer ranges so forts had to shift their emphasis from short-range crossfire to long-range frontal fire. This was the main reason for the change from star forts to polygonal forts.
The polygonal fort tried to mass as many cannon as possible along the ramparts. And while Montlambert's caponiers were designed with massive artillery, he was still thinking in terms of the short-range crossfire of star fort days so they mostly fired across the face of the fort. The caponiers that were actually built were mostly for riflemen, revolving small-caliber artillery, and then machineguns, for a last defense of the ditch, as the issue would really be decided at long range with frontal fire from both the fort and the besiegers. But as the range and power of artillery increased, having all the fort's guns exposed on the ramparts, or even having ramparts at all, became too vulnerable. Thus, eventually, forts became almost entirely subterranean concrete boxes with only a few (often retractable) turrets above ground. They still had a ditch but the caponiers had been replaced by light batteries (revolving cannon and machineguns) at the angles of the counterscarp to fire along the ditch. That was still quite difficult to storm, so then ultra-heavy howitzers were developed to fire literal bunker-busting, battleship-caliber armor-piercing shells into the subterranean core of the fort, and steam trains and tractors could move these to the front lines. The forts had no answer to this, even though some continued to be built, such as the Maginot Line. And then airpower made all this sort of thing rather moot.
Yes. Next step was the trench, weaker than a concrete fortress, but much more resilient and, actually, almost impregnable. Next step after the next step was coming back to the hard fortress, but in a mobile arrangement, called tank.
Thank you for this. It's very clear that this video is like half cooked, like cut in half. Not just how they said methods of attackers had to be adjusted but then practically didn't explain / show anything, but also from the opposite side - the defenders. They said about that key factor was increase of firepower, caponiers, amassing canons - and here showing even pretty funny high artillery tower - but then not presenting anything how did it work, what did it change exactly. So caponiers were so crucial development, something defining polygonal forts and then it's presented that when attackers reached the line of defence they just... storm though it and it's over? Like huh? Video might seem as a nice work, but it's very poor really. It's clear just on logical and structural level. From your comment I've realized it's even much worse and thanks very much.
@@MarionFR Well, Marion. If You will have the opportunity of travelling in Italy, within a radius of 150 km around Turin (my home) You could see, and visit, twenty centuries of military architecture, from Ancient Rome to Maginot. Perhaps the best way to understand how they worked. In Turin there is, too, one of the most important Artillery Museum in Europe, collecting guns from XV to XX Century. Wellcome.
Nice comment, it's an alright overview but it seems like a remake of the video on star fortresses. I was always asking for more explanations but he quickly moved on to the next point. I think this is a subject that can't be broken down in this way, as it covers centuries of history, many wars, many fortification designs, perspectives from defenders and attackers and the wider world of fortifications and weapons.
Fort Tigné in Malta might be the earliest 'modern' polygonal fortress. It was ordered by Grand Master Emmanuel de Rohan-Polduc, and designed by the Order of Saint John' engineer Antoine Étienne de Tousard, to be finished in 1795.
Damn I was just admiring the finishing touches on my new polygonal fortress . 😮

Can you do a “how to pay siege to an island star/pentagonal fort”? Where little to no land approach exists
Have the better navy andlay suege or hope they are not complete then you just need cuning. Like how that Spainire commander took ranmpa florida wirth basically nothing despite everyone else thinking it was impossible even with the British navy... But because it wasn't complete it was easy just sail under the gunfire and watch the cannon balls ail safely over head... This was during tghe americain revolution by the way adn was the most underrate cluctch play pof the war.
@@GreenBlueWalkthrough Proofread what you write before hitting Reply.
Star and polygonal have both covering fire along the wall. Both were also open battery platforms build against direct fire at their origin, using mortars seems the best solution.
Sail close to the fort flying friendly colors, disembark your troops into boats on the seaward side, open up on the fortress at the last second and keep up the barrage to cover the landing force. When they reach the island, they need to scale the walls or breach the gates quickly, or they won't last long in such an exposed position.
"L'audace, l'audace, toujour l'audace."
I'm paraphrasing Cochrane's reduction of three forts in South America from memory, so please look it up and refine it before attempting.
increadible, there arent that many videos i can find explaining these forts well
appreciate the nod to humane warfare at the end, laying out when it was strategically sensible and therefore morally acceptable to surrender, a very valuable lesson
surrender after the last wall falls? my brother in the Emperor, your body is your last wall
So house-to-house combats using suicide bombers and armed civilians are the real last line of defense, as it was at the Battle of Shanghai Warehouse with Dare To Die corp wearing civilian clothes carrying bags of grenades?

I was worried my star fortress expertise was getting out of date. Thanks, Sand.
I woke up today really bothered. The realization hit me as I drank my Earl Grey tea that i had no idea how to attack a polygonal fortress in the 18th and 19th century. One can imagine my wry smile as i stumbled across this timely recommendation. You're in big trouble now Polygonal Fortresses of the 18th and 19 century. I'm coming for you.
Interesting war history, thanks! These tactics were used later on too!
Glad there is some focus on the 19th century aswell on this channel!

Ah, another siege classic! Love it!
9:05 seeing a photograph of such "old-school" mortars in action feels surreal. These look downright medieval.

To an extent, the tactics were similar. However, the difference lay in the fortifications that were being used by the Confederates. Rather than developing full Star Fortresses with brick construction, the Dimmock Line (the main defensive system around Petersburg) relied on a mix of trenches, batteries, and outward-facing fortifications, which acted more as oversized artillery batteries than Star Fortresses.
The only fully enclosed fortification within the Petersburg and Richmond defenses was Fort Darling - located at Drewry’s Bluff - that was a five-pointed Star Fortification made entirely out of earthen material.
The reason for this choice was rather simple; if the Union took the fortification, they would have virtually nothing to defend themselves against an assault from the Confederate Positions, thus making it difficult to defend their gains.
Whenever the Federals captured a fortification - such as Battery No. 5 on the Dimmock line or Fort Harrison on Richmond’s Eastern Defensive Line - they would have to engineer and construct new sections of walls towards the Westward-facing sections of the fortification in order to rectify the lack of defenses along those sections.
However, even when the Federals took those positions and reincorporated it into their works, the Confederates would simply build a new defensive line behind the captured position. Both Battery No 5 and Fort Harrison would see this happen with the Confederates taking up position along a new defensive line a short distance from their prior line, thus making any gains near meaningless.
It’s why Grant opted to wrap his army around Petersburg and cut off the railroad and plank roads leading into the city, thus starving it and - in turn - the City of Richmond.
Yeah that map had basically nothing in common with Petersburg or its siege.
Two things I've noticed:
1) the role of towers: Renaissance castles had cannon towers, starforts mostly didn't but then they briefly reappeared in polygonal forts. This leaves the question if they had also observation towers or posts to spot the enemy early or organising resistance. With Starforts or polygonal forts with outposts, organising a defense must have been really difficult without telecommunication...
Obviously, the lack of towers doesn't confirm their absence. Starforts were altered during wartime preparations, as some buildings were torn down and reinforcements were made. Possibly further trenches and obstacles were added as well. A wooden tower wouldn't cost much by comparison and it would be difficult to hit, unlike a solid tower...
2) How did the outposts work? Yes, they were meant to engage the enemy and withstand somewhat a siege, but they were too small to be held indefinitely and would be rather easy to encircle. Who would want to man the post, if you know that you'll be fighting to the bitter end? Alternatively, you might build an escape tunnel, but that's quite costly...
You know, you never know if you suddenly find yourself in the 18th century. That is what I tell myself.
A video on the siege of Paris in 1871 would be nice.
Your videos are always so well researched. Have you considered making one about more modern fortifications? Like the sere de rivieres system or evwn the maginot line?
Thanks for the tutorial, I am now going off in my time machine to the 18th century to go test it out :D
i love these, incredible animation.
Immaculate video, many thanks
To say medieval walls were “no match” for large cannons is an oversimplification. They certainly weren’t nearly as durable as wide bastion walls, but several meters of stone is never easy to breach, even with cannons. There are many cases of medieval fortifications sustaining siege via cannons.
Thanks this will come in handy soon.
I often wonder what a 'modern fortress ' would consist of. Had better artillery not made it obsolete. I'll always be that little boy building castles with LEGOS. Fantastic video as always!
Artillery didn't make permanent fortifications obsolete, the Maginot line was built after all, nuclear weapons did.
Thank u
this information will come in handy
I love this channel.
6:17 - poor lad being blown to bits!

Thanks for the tutorial, it worked!
Incredible video.
By the way, the Tower of Belém in Lisbon, built finished in 1520, kind of reminds me of a cross between a tall medieval tower and a polygon fortress - that is, passing over the intermediary star phase. The three-faced water side is remarkably like a polygon.
Great video!
The point of fortress, just like a current military patrol base or logistical base is not to sit inside and wait to be attacked. The point was to project power. When an Amry you could not whip began to invade you had to vacate and dismantle the fortress and begin fighting a regard action and orderly retreat to ground you can defend. Unless you are absolutely positive that a relief Army, along with your soldiers will be powerful enough to defeat your enemies.
Fortresses are good for a place where your soldiers can truly rest and recover from defensive patrols and then refit and continue to conduct patrols.
They were meant as a base from which to launch operations from 😊
I think I can soon get a bachelor's in siegonomics
nice to see the american civil war starting to creep in. it was as much a bridge between the old world fighting of the 18th century and a prelude to the modern fighting of the 20th century
*furiously writes for D&D and Worldbuilding
8:47 I'd love to see the full episode on this siege
So this video leaves me with an unanswered question: how was the polygonal fortressvmore resilient to the formal siege than the preceding star fortress? The formal siege you described here looks basically identical to one you described vs star fort in its video, and I didn't quite get from the video what new challenges were presented by the polygonal fort and how did the attackers adapt to them
There are probably several points:
-The forts meant that the besiegers had to start much further out.
-Riochets were much weaker (their strength against bastioned fortifications was that you could skip them along the ramparts )
-Casemates where of course much harder to surpress than open canon emplacements, meaning the defenders were much better at firing back.
-More and more concentrated artillery made counter battery fire much more effective
@@TheWampam And as well, the fortification was more dispersed and disconnected, meaning there would be many batteries and earthworks to capture along to the main fort
You should check out the castle building game Tiny Glade to make the “ideal” fortress.
this is so interesting, i love your stuff! (also not to nag, but are y'all planning on finishing the 30 year's war series anytime?)

Love your siege videos
Her: Babe what are you doing up at 3 am
Me: Making sure I'm ready for my opponent's advances in siegecraft
Excellent
One thing I always thought was funny was how in Empire Total war, defending the square fortress was possible with 4 units (one for each side) but defending the star fortress which was like 5x more expensive required 10 units to properly defend (two for each spoke) and because the perimeter of the fort was made exponentially longer it was much easier for an enemy to mass all his men at one spoke and overwhelm you there because it would take you forever to re-position.
That's because the main idea of a star fortress is the heavie use of artillery while defending, such thing you can't do in the game
@@thereynaldosan7695 No you can, the forts have built in swivel guns that will fire, BUT you need to have each face of the wall garisoned by a unit to activate them, hence the necessity for a minimum of 10 units which in the game is rather difficult and uncommon to do.
Ye I agree, I think sieges in empire were done quite horribly even though they have the potential to be really fun. The guns should've gotten deadlier with each progression and should've been manned by their own gunners. It's stupid how forts are left completely empty if you don't have a 150 man line infantry unit in there (that can only take position on one part of the wall.)
It's also way to easy to approach the fort, there's no heavy artillery pieces that require progressive siegeworks. you can run up to the fort with minimal casualties and win. If they ever do another gunpowder total war they should add a separate siege system I think.

Thank you very much!
Fascinating.
Since this video is about Polygonal Fortresses, you could do a video on the siege of Przemysl. A staggering siege for sure.
I will use these tips the next time I lay siege to a polygonal castle
Born to early to lay siege to Death Star born to late to lay siege to a polygonal fortress
Really could have used this vid 200 years ago.
seems obvious in hindsight, don't give up land so easily since vobont's system uses that land to build the trenches
That is indeed why building outer works and fortification systems became more and more common
Never thought a siege would be so elaborate. I thought it was all just about making them starve to death and ahoot ablot of cannon balls
Interesting, didn't know about this historical stage of development in fortress defense vs sieges.
I would love a game centered on asymmetrical siege warfare of Star and Polygonal Fortresses.
There are siege rules in the back of "Warfare in the Age of Reason" which is a set of rules for tabletop miniatures. In theory, you need model soldiers and terrain. However, it could be played with pen and paper. It just won't be nearly as pretty.

That makes me think, any chance of you making a video on the siege of Belfort in 1870 - 1871 ?
The place was reinforced by Vauban and later again during Napoleon's time, and saw many interesting aspects of late XIXth century siege warfare, including a failed relief attempt that failed only a few kilometers away from the city.
