Editing Hive Fleet Dagon (section)

== Interrupting the Achilus Crusade ==

Hive Fleet Dagon was first encountered in the Jericho Reach, an area of the galaxy filled to the brim with [[heresy]] and alien species. The [[Imperium]] had launched decades ago a crusade to try and push back the forces of [[Chaos]], the [[Tau]] and other minor [[xenos]] species advancing into that border. The arrival of Dagon threw a wrench into the crusading forces's plans, difficulting and/or outright blocking space travel with the Shadow in the [[Warp]] (and, you know, eating Imperial planets). With at least nine Imperial worlds consumed, the Tyranid forces quickly became a top priority threat to the Imperial authorities. Luckily, there were a decent amount of [[Deathwatch]] forces in the area already, so they managed to push most of the Tyranid incursions back, to regroup, reorganize and rethink their strategy against this new foe. The Imperial losses were considerable, however. Their leadership in certain areas had been almost fully destroyed and left out of commission, with similar losses in regards to their troops. And on top of that, Tau and Chaos forces decided to take advantage of this and push their effords against Mankind's borders even further.

It took the combined forces of the Deathwatch, the [[Imperial Navy]] and a lot of [[Imperial Guard]] regiments to push back Dagon. A desperate concentration of forces on the planet Treyen managed to keep in check the tyranid's advance, and the quick and decisive effect of the Imperial Navy managed to make a dent on the Great Devourer's advance. Right now, they are trying to surround Hive Fleet Dagon in order to stop them from spreading to some other sector.
