''"...Stories told that, in a time consigned to legend, Father Isstvan himself had sung the wold into being with music for his Warsingers to hear and interpret. Father Isstvan was, it seemed, a fertile god and had spread his seed far and wide across the stars, nameless mothers bearing him countless children with which he had populated the first ages of the world.

''...the myths of Isstvan, which told of the children of Father Isstvan who turned from his light and led their hosts against their benevolent sire. A terrible war followed. The Lost Children, as they came to be known, were finally defeated in a great battle and their armies destroyed. Instead of slaying his wayward children, Father Isstvan banished them to Isstvan V, a desolate place of black deserts and ashen wastelands."''

[[File:Urgall_depression.jpg|thumb|right|500px|Probably how it looked like without thousands of dead Astartes and tanks lying around.]]
"The Battle of Isstvan V", "That Huge Fuckup", or '''the Drop Site Massacre''' as it would be better remembered as later, was one of the major defining battles of the [[Horus Heresy]] that occurred circa 4 months after the [[Battle of Isstvan III]]. After the revelation that [[Horus]] had flipped him the bird, the [[Emperor]] threw a huge tantrum and sent the loyal Primarchs and their [[first Founding|Legions]] to deal with the traitors: the [[Black Legion|Sons of Horus]], [[World Eaters]], the [[Emperor's Children]] and [[Death Guard]]. The [[Iron Hands]], [[Salamanders]], and [[Raven Guard]], being the closest, were sent as the vanguard of the Imperial force. The vanguard legions would be the hammer that would break the traitors against the anvil that would be the [[Iron Warriors]], [[Night Lords]], [[Word Bearers]], and [[Alpha Legion]]. 

Little did the loyalists know that [[Not as planned|the anvil had already betrayed the Emperor]] before arriving at Isstvan V. By this time, fully half of all Primarchs and their respective Legions had been swayed by Horus in either joining him in his path to becoming the rightful leader of Mankind or by realizing that the [[Chaos Gods]] are much more favourable subjects of worship. 

And these legions would now have to [[rip and tear|fight it out]] like adult men pumped up with butthurt, big guns and testosterone on the depressingly lifeless deserts of Isstvan V.

==[[Anal Circumference|The Battle]]==
While making battle with the remnants of the loyalists on Isstvan III, Horus sent [[Fulgrim]] to the Urgall Depression, a volcanic valley on Isstvan V, to dig trenches, build barricades and bunkers, and fortify the ancient abandoned fortress complexes there. Imagine the fabulous, pinky Emperor's Children staining their perfectly blonde hair and digging in the mud. Yeah, the decision did not sit well with Fulgrim or his men, but they did their job well in spite of their insistence that the Iron Warriors should've done it instead. Despite Fulgrim's characteristic bitching about having to do actual work, Horus got him to shut up by telling him that he was the only person he could rely on to make the defenses "perfect". The reality of course is that he probably just did it to spite him, as Fulgrim's recent fuck-up with Ferrus Manus had given Horus a significant headache. By the time the loyalists got there, the Emperor's Children had built a ton of anti-air and -missile batteries, forcing the attackers to refrain from [[Exterminatus]] everyone from orbit and being done with it. The loyalists bombarded the site from orbit anyway, and predictably achieved nothing. The bombardment was made possible by the fact that the traitor fleet elements were nowhere to be found, which was a bit disquieting for the loyalists but they ultimately brushed it off as unimportant (spoiler alert, it wasn't). Could they have laid seige from orbit and called for more Imperial Army ships and aircraft to assist in destroying the air and missile defenses and then blow up the planet?  Yes.  Could they have just shot a cyclonic torpedo into any other part of the planet than the specific little area the traitors were in? Yes. But as everyone knows, intelligence is illegal in Warhammer.

The initial plan from the three loyalist legions was to just wait for the other four supposedly loyal legions to arrive, at which point they would all descend to the planet together and steamroll the traitors. However, when word arrived from the other four legions that their ETA would be in a few hours, Ferrus convinced Vulkan and Corax that the three legions on site should attack immediately and do as much damage as possible. It hardly needs to be said that this was a stupid idea. There was no pressing need to attack the traitors; the defenses were already functional, the traitor positions were already manned, the loyalists' numbers weren't enough for a decisive advantage against a defensible position, and as far as the loyalists knew the traitors had no reinforcements incoming and no void assets in system. All three loyalist Primarchs knew that they did not have the forces necessary to guarantee victory; the Iron Hands contingent was comprised of little more than Ferrus's terminator elites, and the Raven Guard and Salamanders had always been amongst the smallest legions. However, Ferrus was extremely pissed about Fulgrim's betrayal and even more pissed that the first person Fulgrim had gone to to try to turn was him. Ferrus was obsessed with being strong, and Fulgrim's attempt at turning him had stirred up the possibility that Fulgrim had seen some weakness in him that would make Fulgrim think he could get him to betray the Emperor. Additionally, virtually nothing was more important in the Medusan culture than loyalty to one's clan or family. The absolute last thing Ferrus wanted anyone, especially his brothers, thinking of him was that he could be convinced to betray his own father. Yet it was ''Ferrus Manus'' of all people, the staunch Iron Gorgon of Medusa, who had been the one Primarch approached with an argument to commit such a betrayal. As might be imagined, the situation had Ferrus practically frothing at the mouth. He wanted to put down the Traitors as quickly and brutally as possible, as if he managed that, his loyalty could not possibly be in any sort of question, and whatever esteem he thought he had lost in the eyes of his brothers would be restored. Fulgrim also trashed his flagship upon departure, which must have helped exacerbate Ferrus' assmadery.

Interestingly enough, the decision to attack the traitors was agreed to by ''Corvus Corax'' of all people; the one Primarch who would have been the most likely to recognize that attacking a fortified position with an inferior force while friendly reinforcements were just hours away was pants-on-head retarded. One explanation for this seemingly monumental lapse in judgement was the reason Ferrus gave to his brothers for attacking. Ferrus argued that with the traitor void elements absent, the loyalists had a situational advantage that had to be immediately exploited. Of course this was still stupid; among other things the loyalists had complete superiority in local space, and if the traitor fleet returned, it would have had to first drive off or destroy the loyalist fleet in order to provide any support to its ground forces. Such a battle would have occurred regardless of whether or not the loyalists had yet been deployed planetside, and if the traitors won the void engagement, they would have been able to blast the unshielded loyalist ground forces into pasta sauce via orbital bombardment. If the traitor fleet lost, the situation would be unchanged. Additionally, the loyalists still believed that they would be reinforced by a whole four other loyal legions in a few hours, which obviously would have included all the void resources of those legions. The reality was that Vulkan and Corax almost certainly would have known that it would have been better to wait for reinforcements, but Ferrus would likely have simply engaged on his own if they had refused to aid him. As was previously mentioned, Ferrus's reasoning was colored significantly by emotion, and he was quite choleric even at the best of times. With him undoubtedly being as angry as he had ever been, and reinforcements speeding into the system, Vulkan and Corax likely believed it was simply not worth arguing with Ferrus about the matter. As would be seen later on, their plan appeared to be to accompany their brother to the surface, bloody the Traitors as well as they could, and then let the other four legions relieve them when they arrived. The plan would of course be...less than ideal, but the two most soft spoken Primarchs in the entire Imperium probably lacked the force of personality to change Ferrus's mind. And, of course, neither Vulkan nor Corax were counting on their [[Alpha Legion|reinforcements being Traitors]].

Nearly 30.000 Astartes (probably closer to 300k thanks to retcon), the [[Adeptus Mechanicus|Mechanicum]]'s Dies Irae (the <s>Warlord</s> IMPERATOR Titan present at Isstvan III), other Dark Mechanicum machines and the [[Imperial Guard|Guard]] artillery pieces were on the defense. Nearly 40.000 loyalists (again, more like 350k) were on the offense and went about, venting their raeg after deploying á la [[Steel Rain|STEHL RÄHN]] tactics into the middle of the defenders. Felblades and their variants, the Land Raiders, Predators, Whirlwind, and Army artillery, deployed behind on the hills and around the depression. 
[[Mortarion]], [[Fulgrim]] and [[Angron]] actively led their respective Legions on the ground, while [[Horus]] probably sat on a balcony in the fortress like a total boss, orchestrating the whole traitor army by whispering commands to everyone through the vox. Additionally, there are anecdotal reports that he was also seen sipping red wine while petting a large white cat on his lap. In addition, to the loyal [[Corax]], [[Ferrus Manus]] and [[Vulkan]], four additional traitor Primarchs arrived later: [[Lorgar]], [[Alpharius]], [[Perturabo]] and [[Konrad Curze]].

Imagine around 70.000 Astartes (More like over a half MILLION Space Marines!) + all the vehicles of their legions + puny humans and their artillery in a terribly confined space, in a line less than 20 kilometers wide. Armies that could conquer entire planetary systems were crammed into a medium-sized, open valley.

[[File:DSM Map.PNG|400px|left|thumb|Probably the first time that a couple of Primarchs pretty much said, "Maaaaannnnnn.......aren't we all fucked".]]

The Iron Hands, Salamanders, and Raven Guard led the first and only assault on the traitor fortress complex while awaiting reinforcements from the other four legions. When those arrived, the Salamanders and Raven Guard fell back to catch their breath and resupply, while the Iron Hands decided to push forwards over the retreating pretending-to-be-panicking traitors. As the loyalists neared their initial LZ, the newly arrived "loyalists" (fresh and more than 40.000 of them (more like +300k with retcon)) opened fire, revealing their true allegiance. As this happened, the Sons of Horus, World Eaters, Emperor's Children, and Death Guard attacked from the rear, completely encircling them. 

The loyalists were caught completely off guard and were fucked over almost as hard as [[Lamenters|these guys]]. Even worse was the loss of two of the loyal Primarchs as Ferrus Manus received a Classic Slaaneshi Daemonette Treatment (meaning the subject's head is chopped off exactly the same second the orgasm is reached, resulting in a forever erect and stone-hard penis), and Vulkan disappeared in a nuclear detonation and presumed dead-as-fuck before [[Perpetual|turning up again]] pretty fucking quickly in [[Konrad Curze|papa emo himself's]] torture chambers, being killed over and over, which resulted in him becoming insane but eventually managing to escape. Corax ''almost'' managed to knock off Lorgar, but unfortunately for every sapient entity in the galaxy who wasn't Chaos aligned, Curze saved him. In the Horus Heresy novel, ''Fulgrim'' there was a brief but badass mention of Corax having been knocked unconscious in the battle and his sons desperately dragging him to a waiting Thunderhawk amongst the chaos but this got retconned in a novel soon after. In orbit, the loyalist fleet had been caught similarly unawares by the traitor forces, this spess battle was just slightly less one-sided as the ground campaign had been. The loyalist ships had been on military alert due to being in an active warzone, and virtually all of them have had their shields up when the betrayal occured. Ultimately however, the loyalist fleet was outmatched, particularly when the fleet elements of the initial four traitor legions returned. The loyalist fleet was scattered and many vessels were destroyed, but many more were simply driven off or escaped, though the ones that stuck around long enough to receive some surviving loyalist marine escapees would be in an invariably shit shape. 

The loyalist ground forces were forced to perform a desperate emergency extraction and barely managed to escape, with the three legions crippled and largely unable to participate in the Heresy after the massacre (no shit). The Massacre remains a bitter memory for the three loyalist legions and their successor chapters ten-thousand years later. [[Rape|Each legion lost between 75 and 85 % of their numbers in just a few hours]]. The Raven Guard would get even more thoroughly fucked over trying to recover their numbers. The Salamanders, being already one of the smallest legions, would not even have enough marines to fill their own chapter, let alone a successor at the [[Second Founding]]. The Iron Hands and their Primarch would forever become the face of most beheading jokes before being almost entirely forgotten.

Due to the chaotic evacuation, many surviving legionaries grouped up into cells collectively referred to as the Shattered Legions, many of whom would be stuck behind enemy lines following their harrowed escape, unable to communicate with Terra or even eachother due to their damaged space vessels physically incapable of sending and/or receiving communications or due to the warp storm fuckery taking place soon after the massacre. They would have little to no clue as to how the war is going and indeed, if the Emperor is even alive or if the throne world is now a searing ball of death. Due to their catastrophic losses in manpower and resources, these groups engaged in guerrilla warfare with the intention of bleeding the traitor forces any way they could. This was rather effective: one cell led by Shadrak Meduson inflicted a great number of losses on the traitors while another group led by Autek Mor achieved a number of badass achievements such as blowing up the World Eater's fief world of Bodt with its [[Rip and Tear|fucking moon ]]. 


===Emperor's Children Perspective===
{{Topquote|Horus has seen the truth of things, my brother. The Emperor has already abandoned us and even now plots his apotheosis. He lied to us all, Ferrus. We were nothing more than tools to win back the galaxy in preparations his ascension! The perfect being he pretended to be was a filthy lie!|Fulgrim's first attempt to sway Ferrus Manus to [[Chaos]].}}

Fulgrim was massively disappointed and depressed that Ferrus Manus would not be swayed to Horus's side and that he would be forced to die (Horus's own words). By failing to convert his ugly bro in his own flagship, Fulgrim knocked Ferrus out with a hammer blow to the jaw that would have sent an Astartes head flying for a mile, and fled into the Warp to deliver the bad news to Horus.

Shortly thereafter the transformation of the Emperor's Children into the metal-and-shoegaze-loving Noise Marines that we know and love was completed, both chaotically and genetically. [[Fabius Bile|Fabulous Bile]] made sure to add a ton of physical and genetic alterations to his brothers, like speed enhancements and the ability to produce ear-shattering, bone-breaking sonic waves by opening the mouth a little too wide, flailing ones arms in circles and generally looking like a skinned bear recently castrated without anaesthesia. 

''In the center of the traitor line, the Emperor's Children fought with unremitting cruelty, its warriors howling with savage glee as they killed their former brothers. Unnatural horrors of mutilations and degradation were visited upon the living and the dead as Fulgrim's Legion repulsed every attack. Bizarrely clad warriors in Mark IV plate draped in stretched skin cavorted in the midst of the deadliest combats, fighting without helmets, their jaws wired open as they unleashed a  hideous screaming. They bore unknown weaponry and fired echoing blasts of atonal harmonics that ripped bloody canyons in the massed ranks of the Iron Hands. Great pipes and loudspeakers fixed to their armour amplified the screaming vibrations of their killing music, and deafening sound waves tore apart warriors and armored vehicles.''

Lastly, in the ending moments of the battle, Fulgrim chose to reveal himself and meet the Gorgon's challenge. The duel that took place next was incredible in its emotional proportions and significance, so go and read the fifth HH book, "Fulgrim". It's an [[awesome]] read. Spoiler: Fulgrim attempted to resist the Laer Sword which had ultimately corrupted him one last time by pulling the mortal blow on his bro Ferrus, regaining a last moment of clarity when seeing what had become of his legion. The Greater daemon in the Sword took no chances by forcing Fulgrim into killing his BFF Ferrus and then giving him the oblivion he craved following the murder ([[Troll|by possessing his body, of course]]).

===Word Bearers Perspective===
By the time the legion of the first heretics arrived at Isstvan, the first possessed Space Marines, the so-called Gal Vorbak ("Blessed Sons") were now a part of the Word Bearers with the power to summon daemons. The story of the first possessed marines is incredibly interesting and can be fully enjoyed by reading the HH novel "The First Heretic". The book also details the confrontation between Corax, Lorgar and then Curze; really cool shit. The first mention of the [[Legio Cybernetica]] robots is also here and present during the battle. 

Lorgar showed hesitation all this time, even during the battle itself. He felt shame for causing so much chaos and bloodshed when he only wanted to topple Big E from his throne. He had never imagined the scale of this betrayal. And thus when he saw Corax slaughtering the possessed marines, he ran towards Corax with no hope of surviving the confrontation and not caring either in equal measure against the wishes of his most "trustworthy" advisors Erebus and Kor Phaeron (who almost got a heart attack when Lorgar decided to engage). Such a sensitive soul, don't you think? *sob*.

''"- I will kill you, Lorgar."''

''"- I know. But I have seen what will be. Our father, a bloodless corpse enthroned upon gold, and screaming into the void forever."'' 

But before Corax could finish the job Lorgar was conveniently saved by the greatest psychopath under Horus' command, i.e. Curze... well maybe Angron with his fried brain might be another contender for "most crazy up Primarch", but that's another story. No, Fulgrim doesn't count; he was too busy getting possessed. To his credit, if Empy hadn't lied to all of his sons the whole Heresy might not even have begun in the first place - Fulgrim had no chance of fending off his corruption without knowing of Chaos and where the strange voices in his head came from, and once he finally realized that the insidious whispers were actually real he was already too far down the road to damnation for it to matter. I mean he was looking at a picture made of excrements and other bodily fluids by that point, and mind you, that was before he ''officially'' turned traitor.

===Iron Hands Perspective===
Being extremely pissed of at Fulgrim, [[Ferrus Manus|The Gorgon]] could not hold his load and decided to lead the assault against the traitors holed up in their fortress. Proving once again that they are tough bastards in a fight, they set the standard for the future generations of Iron Hands and their successor chapters during this battle. Even though they nearly got wiped out, they recovered eventually enough to give birth to successor chapters like the [[Red Talons]].

Two late arrivals, Shadrak Meduson and Autek Mor, gathered as many survivors as they could - Meduson piecing together a coalition of Iron Hands, Raven Guards, and Salamanders - and embarked on two epic, but very different guerrilla campaigns against Horus. Let's not forget that the cybernetic robot marines of the 40k still cling to their delusion - I mean ''entirely logical'' conviction - that Ferrus would have lived if the Salamanders and Raven Guard just had had as much balls of steel as they had and died a manly death in the crossfire of the traitors instead of trying to disengage, the cowardly bastards. Another proof that the flesh is weak. Wait, what organic part can I replace next?

===Raven Guard Perspective===
''The screaming raptors of the Raven Guard cut a swathe through the enemy's right flank, his fearsome assault wings dropping from above on the fire of jump packs, and slaughtering their foes with shrieking sweeps of curled blades.''

While the other legions lost the biggest percentage of their members, the Raven Guard lost the most in pure numbers, leading Corax to resort to technology from the [[Dark Age of Technology|Dark Age]] to replenish his ranks. That can be read in HH novel "Deliverance Lost". 

''The ground murmured with his landing. Claws slashed from their power-fist housing with silver flashes, and shimmering wings of dark metal reached up from his shoulders into the air above. Slowly, so painfully slowly, he raised his head to the traitors. Black eyes stared from a face whiter than Imperial Marble, and written across the pale features was the most consummate, complete anger Argel Tal had ever seen. It was an emotion truer and deeper even that the rage that ruined the faces of the daemons within the warp.
''But it was not anger, nor rage. It went beyond both. [[Awesome|This was wrath, in physical form.]]''

===Salamanders Perspective===
{{Topquote|...the mighty figure of Vulkan strode through the torrents of bolts, killing with every sweep of his sword and shot of the weapon his brother Ferrus had forged in his name. A colossal explosion erupted at the primarch's feet, wreathing him in killing fire, and dozens of his Firedrakes were hurled through the air, their armour molten and the flesh seared from their bones. Vulkan marched through the fire unscathed, continuing to kill traitors without missing a beat.|from the eyes of Gabriel Santor, First Company Captain of the Iron Hands.}}

The Salamanders did not have a good time during this party. They lost a massive percentage of their forces (from 89,000 to little over 700 from some sources!). What's more, Vulkan was cut off from his Legion by a nuke and got captured by Night Haunter.

==The End Note==
All of the Traitor legions and Primarchs were present at Isstvan V (except [[Magnus the Red]]), with almost all their forces as well. Five of them would strike directly at Terra, especially now that Mars was under Dark Mechanicum control. The Alpha Legion was sent to harass the [[White Scars]], who were on their way to Prospero to figure out what the hell had happened to the Thousand Sons since the Khan had been friends with Magnus and wanted to know if the rumours about the Wolves fucking the place up were true. At that point he did not even really know what exactly was going on, only that shit had been hitting the fan. 

The Night Lords were sent to some important system in the Eastern Fringe to terrorize and eventually take over some still-loyal Forge Worlds there while also fucking with the Dark Angels. Perturabo was permitted to send his fleet to vent his specially reserved frustration on an [[Imperial Fists|Imperial Fist]] armada that had not made it to Isstvan V in time and was mustering at [[Battle of Phall|Phall]] [[What|where he would have had his ass handed to him by a lowly Space Marine Captain]] if they had not been forced to disengage. To make things worse, if the Imperial Fists fleet had not received the order from Terra at the exact moment the assault on Perturabo's flagship took place, chances are they might even have been successful (as that way the planned second wave would never manifest and the Imperial Fists on the Iron Warriors' flagship would be slaughtered alongside most of the armada being massacred as they tried to disengage). The short story ends with Perturabo running the calculations and realizing he would have lost the battle. 

Kor Phaeron deployed alongside a detachment of the Word Bearers whose faith in Chaos was suspect to join the [[Ultramarines]] at their mustering at Calth, at which time they would reveal their allegiance to Roboute Guilliman and begin the [[Battle of Calth]]. Lorgar and Erebus would join them with the bulk of their legion's forces alongside the World Eaters to begin the Shadow Crusade, which would ultimately cut off the Ultramarines from the rest of the galaxy between their campaign and the creation of the Ruinstorm.
