I had:
a) exactly 20 dragons;
b) they appeared immediately;
c) there were no other tasks besides those 20 dragons.
Check if you are entering the portal correctly (it seems you don't need to enter it), try replaying. In general, a script to complete the mission should have triggered... It's a strange situation.
if you mean in the army, then yes
regarding the portal, I point at it, and a red sword appears.
