At a wild guess I'd say Phytophthora but from the pics it is a wild guess really. If you can see any darkened weepy patches it possibly is as it's quite common on chestnuts at the moment

Whilst in principle I'd agree with Bob given the bark necrosis present there doesn't apear to be any active 'oozing' /bleeding as I would expect to see.

 

Can't help thinking some mechanical damage may have alos been inccured by the trees given the type of damage and their location and the (seemingly)recent addition to the perimeter fence with the security bits on top...dunno!

 

Watch and see..?

 

Cheers..

To this suburbanite, it looks like past vandalism that has had a chance to occlude . Something that I come across far too frequently

I'd go with physical damage before anything else. Probably not got any roots left, either.
