We explicitly know that fighting occurred in the "outer wards". That is where Emmanellain was stationed, and where the dragon killer cannons/ballistae were positioned. From the sounds of it a separate force of dragons/wyverns were sent to assault the city itself. It's possible only the not-so-huge dragons could attack the city directly due to the presence of Daniffen's Collar projecting it's protective barrier.
