What do you think is the Greatest Battle of Warhammer 40,000, this can be from any Black Library novel or Codex. This does include the Hours Heresy and the Great Crusade as they had some of the fiercest battles of the 40K Universes.
Note; Please Explain what these Battle were about and the forces as some are not as well known as other.

I imagine the War in Heaven was a rather titanic campaign: many, many C'tan leading vast legions of Necrons all over the galaxy. A war so powerful it birthed entire species!!!

The first war on Armageddon also sounds pretty good, a primarch actually did something!

I think the Octavian war between the orks and tyranids should be rated up there, to my knowledge that war is still going on.

Siege of The Emperor's palace.

The Battle of Terra, Battle of Macragge, the Tyranid-Octavian War, 2nd War of Armageddon, Battle of Ilyanden are probably the big ones.

The ongoing Battle of Cadia as well probably, as it was said the 13th Black Crusade saw the largest mobilization of Imperial and Chaos forces since the Horus Heresy.

As far as battles go, I'm going to be pretty generic and say the Siege of Terra. But there's reason for it; it is pretty great.

The Great Game.

What about the planet-wide battle for Balhut?

The super massive galaxy spanning Hive Fleet Ninja that attacked and destroyed the Squat Homeworlds that spanned the Center of the Milky Way Galaxy! It was such an awesome battle that every single Squat in existence was snuffed out with a word from the Hive Mind Jervis, never to show it's face in the 40k universe again.

What made the battle so extremely unusual was that not a single race was harmed except for the Squats. Even the Imperium escaped unscathed!

Then, all of a sudden, the Tyranid Hive Fleet Ninja dissappeared, leaving no trace of it's existence...not even in the Tyranid codex.

Truely, this was the greatest Battle of the Warhammer 40,000 Universe.

The Istevaan massecare against the loyalist was so epic, I felt like crying in the end for all those loyalists that gave their lives an fought to the death!

I have a soft spot for the Third Armageddon War, to be honest. A proper fight if ever there was one, says I.

Ullanor! The greatest WAAGH! ever was utterly crushed under the might of 100,000 Astartes and 8 million Imperial Army troops! The celebration after was quite epic also. No bigger gathering of military might before or since then. If that force were to ever gather for war, nothing would stand in its way.

Though obviously the Battle for Terra was more epic. The battle for Mars was pretty intense also.

Are we counting whole wars or just battles? Cuz if it's wars then the Heresy obviously takes the cake, and if it's battles then the Siege of Terra.

The war in heaven is probably the largest one because this war really started to shape the warp into what present 40k is now

all those Black Crusades Failbaddon has been organizing.


the sheer level of Epic Fail is just so awe inspiring. Abbaddon has earned his place in the Book of Heroic Failures(actual book i kid you not. and its an awsome read)

Pretty sure the 4th edition codex has a galactic map with a marker that says 'Squad Homeworld (Destroyed)'. I can't remember the planet name given. Obviously they had more than one world, but it has been noted in a codex.

And considering how much GW wanted to forget about the dwarfs in leather chaps riding trikes, are you really that surprised at the little fanfare given to their passing?

Rhahana Dhandrha

The final Battle, Twighlight of the gods, End of all things.

There are a lot of great battles in the 40k universe. I believe some of the greater ones would have to be: Battle for Macragge, all of Armageddon's great battles, the battle on Rynn's World was pretty great too. (what do you expect for an ork player )

Possibly the war in Hellforged, or the siege of Terra.

The War in Heaven for sure.

I'm pretty sure it's Golgotha (The hill where Jesus was crucifid)
A footnote in the GUard codex says how Yarrick was captured there but escaped with it's "Inhuman" occupants destroyed

I am pretty sure the Squat homeworld wasn't Golgotha.


I belive Golgotha was a world that was retaken is some Crusade. its mentioned in the previous SM codex IIRC. some poem about as UM captain who met his end on Golgotha.

its over in the same galactic arm as Terra IIRC.

sorry but I'm pretty sure it was atleast a world originally controlled by the squats at some point but not their homeworld

maybe, i'll look at my Codex when i get home.

Nothing even comes close!

The Battle for the Emperor's palace.
The razing of craftworld Iyanden should get honourable mention.

Astral Knights versus the Necron World Engine.

Any engagement where a Battle Barge is used as a breaching torpedo has something going for it.

Can i just say Draigo leading his 1 man army against chaos, and winning to the point that daemons stay away from him. In the warp of all places!and only khornes followers have a go any more lol.

I have a soft spot for Iron Cage/Siege of the Eternal Fortress.

I say Emperor's palace, 13th black crusade invasion of cadia (since orks, dark eldar, and eldar also participated), and Armageddon all 3 wars
