Drop Site Massacre

Iron Hands at the Dropsite Massacre, shortly before their Primarch loses his head.

The battle of Isstvan V, that huge fuckup, or the Drop Site Massacre as it would be better known, was one of the major defining battles of the Horus Heresy. After the revelation that Horus had flipped him the bird the Emperor threw a huge tantrum and sent the loyal primarchs and their legions to deal with the traitors. Ferrus Manus, Vulkan, and Corax, being the closest were sent as the vanguard of the Imperial force. Unknown to the loyalists fully half of their brother had betrayed him and the rest were simply waiting to openly declare their allegiance to Horus. After battling against the traitors, and absorbing the loyalist remnants of the traitor legions, the Iron Hands, Salamander, and Raven Guard were pretty fucked up, making their way back to their landing zone to resupply and coordinate with the other recently arrived "loyalists". As they neared the drop site the combined forces of the Iron Warriors, Night Lords, Word Bearers, and Alpha Legion opened fire on them revealing their true allegiance. As this happened the Sons of Horus, World Eaters, Emperor's Children, and Death Guard attacked from their rear. completely encircling them. The loyalists were caught completely off guard and were fucked over almost as hard as these guys. Perhaps even worse was the lose of two of the legion's primarchs, as Ferrus Manus was killed by Fulgrim who chopped his head/dick off, and Vulkan disappeared, but he turned up again pretty fucking quickly, and after pissing offpapa emo himself.

Probably the first time that a couple of Primarchs pretty much said, "Maaaaannnnnn.......aren't we all fucked".

The loyalists were forced to perform an emergency extraction and barely managed to escape, however the three legions were 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 ten-thousand years later. In a few hours they each lost more then at least seventy percent of their forces, and to this day still have not managed to fully recover their losses. The Raven Guard would get even further fucked over trying to recover their lost numbers. The Salamanders, already one of the smallest legions would not even have enough marines to fill their own chapter, let alone a successor at the 2nd founding. The Iron Hands and their primarch would forever become the butt of beheading jokes(refer to the picture caption on the right), plus this also led them to bee the biggest dicks in 40k.

All in all, Horus fucked up everything
