That reminds me of an accident at a friends place.
They put a pregnant mare in a field with "her" stallion, a four year old supposed gelding, that was actually still a stud, ran through the fence to take the mare. The stallions fought and the older stud ended up needing stiches.
They put the stallion in a barn to heal and mended the fence, with hot wire.
Once again the four year old broke the fence, the older stallion looked out of his window and, angry another stud was with his mare, kicked the barn, an overhanging beam fell, hit him, and killed him on the spot.
Needless to say the four year old was given away that day.
