What you cant see in the screenshot:
3 alliance siege engines guarding the courtyard
1 horde demolisher shooting the gate from over a wall
Several alliance guarding the front door (didnt see me there)
No other horde in the courtyard
A hole in the west and the front walls of the courtyard
Try and guess what happened following this screenshot
(sorry for the bad placing of the blizzard frames, pitbull is stuffing up at the moment)
