It looks like the ship had a blackout before it hit. This would have resulted in main engine and steering failure with the resulting allision with one of the bridge piers and the collapse of the bridge. The ship will have a Voyage Data Recorder which will have a record of, amongst other things, engine orders, helm orders, rudder angles, radar pictures and also a sound record of the wheelhouse vocals. The engine room will also have records of all machinery actions.
The ship's Master doesn't physically steer the ship (a common misconception) and there will have been at least one licensed Baltimore pilot giving helm and engine orders (officially called "advising the Master").
There will be questions asked as to why the anchors were't dropped, but I would guess that the ship was going too fast and the time available too short for that too have any effect.
Obviously there's going to be investigations ongoing for months.
