You're probably just missing the 2 non-commander units now sitting in the province. Did you check the army setup screen?
The units don't go in a recruit queue, they just appear as regular army units in the province the next turn. If your Sauromancer is already leading units, the shadow and shade can be appended to the 1st army group he is leading instead of just sitting in the province without a leader.
By the way, summon a revenant to enter the site for you, and put your Sauromancer back to doing some real work
