Well, the dates I added are only approximate, which is why I added the "ca - circa" before each date. Based on all the sources I've read over the last twenty years we do know that the Horus Heresy lasted approximately seven years, with an exact date of the Siege of Terra occuring in the year 30,014 (014.M31), which would place Istvaan III and Istvaan V approximately in 007.M31. We also know that the Ullanor Crusade occured at the dawn of the 31st Millennium, which occurred approximately during 001.M31 (the first year of the new millenium). The dates are actually fairly accurate. After rereading alot of the novels over the last few weeks, I realised the authors usually gives the reader an approximate date by listing how many decades before the Horus Heresy most of these campaigns occurred. If you'd like,

I have a fairly accurate timeline I've been working off of if you would like to verify most of these campaigns. The ones that aren't listed, I've had to go back and painstakingly research each novel to find the approximate dates. I understand with the new Forge World book on the Horus Heresy coming out soon, the dates will most likely have to be revised again. Whether you want to change them back to the original 'Unknown Date' proximations are up to you, but I thought it would be nice if we could finally post some type of clear timeline on the wiki, since Games Workshop won't do the legwork and make an accurate timeline for all of us enthusiasts! Aaargh! So frustrating!
