765.M41:  Chapter Losses to date:  13 Lost in warp, 21 Irrecoverable battle losses, 9 Gene seed failure, 4 Inquisitorial purge, 16 Other circumstances. (For the record,  195 chapters listed above)

THE FOUNDINGS
There have reportedly been 26 foundings so far.
M31- FIRST- PROGENITOR.   (?)-    Legions made up from gene seed samples of the primarchs, even while primarchs scattered and undiscovered.
M31- SECOND- PRIMOGENITOR.  (30,021)- Legions split up into chapters.  It is unclear whether new chapters were built up from gene seed as well.
M33
????- THIRTEENTH- DARK FOUNDING.  Unknown number or fate of chapters.
M36? TWENTY-FIRST.  Known as the Cursed Founding.  Occurs shortly before the age of apostasy (which was in early M36).
M38
M40
??? TWENTY-FIFTH.
M41- (40, 736)- TWENTY-SIXTH.
Astartes Praeses- a group of 20 chapters formed with the express purpose of of guarding the Eye of Terror.
 

PRIMARCHS THAT SURVIVED THE HORUS HERESY
    According to 2nd edition background,  9 of the Primarchs "survived" the Horus Heresy- the rest died or fled into the Eye of Terror.   We know that Sanguinius and Horus died.   We also know (as of WD 261) that Ferrus Manus is presumed dead at Isstvan V (though his body may have been recovered and taken to Mars). We know that Guilliman, Jonson, Khan, Russ, Dorn, Vulkan, and Corax survived (especially since they are mentioned in the most recent Black Templars background).    That  makes 7 loyal primarchs.  The other two could be those from the deleted records (the 2nd and 11th legions).    The more likely possibility is that Konrad Curze and Alpharius count as survivors, as they did not become Daemon Princes nor were they killed until AFTER the heresy.
    Note also that the 2nd edition background indicates that of those 9 primarchs, all of them had died (or disappeared?) after 1400 years (of being  created, presumably).  Their remains have since become relics, particularly the tomb of Roboute Guilliman.  Rumours exist of the possibility that Lemann Russ, Ferrus Manus, Corax, and Lion El' Jonson will return some day, of course...
   Six of the Traitor Primarchs have gone on to become Daemon Princes (Fulgrim, Angron, Mortarion, Magnus the Red, Perturabo, Lorgar).  Konrad Curze is confirmed dead (by an Assassin) according to background in the 2nd Edition Chaos codex and the 3rd edition Assassin codex, though he was killed after the heresy, not during.  The IA article on the Alpha Legion settles the fate of Alpharius- killed in single combat by Roboute Guilliman after the Horus Heresy.  Guilliman was in turn killed by the daemon prince Fulgrim, long after the heresy was over.

THE ISSTVAN V DROP SITE MASSACRES
According to various backgrounds (which all agree on this point), Horus had Five Legions that had sided with him (and against the Emperor) before the Isstvan V event.  Seven legions were sent against him at Isstvan V- Four of which changed sides and joined Horus (referred to most recently in the second printing of the 3rd Edition Codex Chaos Space Marines, and the Index Astartes: Raven Guard- WD 275 p.101), the other Three of which were destroyed (more on that later).

TURNING OF THE LEGIONS
According to IA: Word Bearers (WD 269 p.113), the Word Bearers were the first legion to be corrupted by Chaos.    The Night Lords are stated to have gone renegade before the Horus Heresy even broke out.  The Word Bearers were already followers of Chaos before officially joining Horus, and had also sent a massive force against the Ultramarines homeworlds around this time.  The Emperor's Children were reportedly corrupted by Horus when they were sent to bargain for peace right before the conflict.   The Iron Warriors themselves are specifically said to turn at Isstvan V. The only conflict with the information above is the turning of the World Eaters, whom Horus was sent to subdue before Isstvan V, and he recruits them instead.  It seems unlikely that anyone would send the World Eaters to subdue Horus after they had previously sent Horus to subdue the World Eaters.

ISSTVAN III and THE EISENSTEIN
With the advent of Decipher's Horus Heresy CCG (and corresponding art book), some of the classic background surrounding Horus and the legions has been brought back into light (though it appears to conflict with the background from the Index Astartes articles on some points).  In summary, Horus was wounded on Davin and tended to by the warrior lodges there, who converted Horus to the worship of Chaos.  Horus then had marines from the Emperor's children, World Eaters, and Death Guard inducted into these warrior lodges.  When Horus and these three legions were sent to subdue a tyrant on Isstvan III, Horus and the other corrupted primarchs agreed to eliminate the marines in their legions known to still be loyal to the Emperor.  The loyalists were sent to subdue the planet, and after they succeeded, the traitor ships virus bombed Isstvan III.  It did not kill all the loyalist marines though, and a handful of Emperor's Children, World Eaters, and Death Guard loyalists were still on board the orbiting ships.  Led by Captain Garro of the Death Guard, these loyalists escaped on the frigate Eisenstein to  warn the Emperor of this betrayal.  Some of the loyal Emperor's Children marines (led by captain Tarvitz I believe)  made their way to the planet surface in a Thunderhawk, to tell their suriviving brethren of the betrayal.  A bloody fight ensued over the wasted ruins of Isstvan III when the traitors dropped to the planet to wipe out their loyalist brothers.  The Isstvan III massacres were the first (and possibly last) time marines of the same Legion fought on both sides of a conflict.

3 LEGIONS WIPED OUT?
The Index Astartes articles name these legions, nullifying my original assumption that two of the three Legions destroyed at Isstvan V are the ones Deleted from Records (Number 2 and 11).  In the Iron Hands IA article (WD 261), it is clearly stated that Ferrus Manus and his veterans spearheaded the attack on Horus' forces along with 2 other Legions (and later refers to the Salamanders and Raven Guard legions).   This information is confirmed in the Raven Guard IA (WD 275, p.99).
    Since only a small force of  Iron Hands could get to Isstvan V in time, the rest of the Legion survived the massacre, carrying on to this day and yielding successor chapters even though Ferrus Manus was killed in the conflict.   The Salamanders continue on (though they have no known successor chapters!)-  Vulkan survived the heresy according to the background in Codex: Armageddon (under the Black Templars of all places), so it was possible for the Salamanders to be built back up from almost nothing if need be.  The Raven Guard Legion was shattered, but Corax survived, and resorted to accelerated Zygote development only to create monsters which were never spoken of.  The Raven Guard operated in small squads behind enemy lines until they could finally build up their forces again, nearly a century after the end of the Horus Heresy.  They also welcomed the Index Astartes principle of breaking up the legions, forming 3 successor chapters.
