It was stated (at some point; I have no sources) that the hist alerted the argonians ahead of time about Mehrunes, and so the argonian army had psychological weapon in the hist (makes you do weird s*** if they want), time to prepare, hist sap, pure numbers, and an already pretty good fighting force. Lets not forget that you can barely go into Argonia in Arena, Daggerfall and ESO, and there is still a ton of weird and powerful stuff. The imperial army, while powerful, could barely take "black marsh", and was not well prepared for such and assault, and the imperials received the brunt of the assault as well, with the assassinations and direct invasion of Merhunes.
