Very short question on assassination and spying

[Wauthan]

1. No the assassin is always alone during his assassination run. Thank heavens! They are troublesome enough as it is. The stealthy units under his command is a real blessing when someone tries to assassinate your assassins or you need to take a province with force since it's guarded by something no assassin can beat in melee.

The Pangea assassin Hero is a really big pain using this strategy.
