Wouldn’t it have taken some doing to cause them to detonate?

It would take a lot of doing. A nuclear reaction requires huge compression of a core of fissile elements by precisely focusing detonations around it and driving it together. A generic explosion tends to spread material outward. Unless the bombs were unlocked and armed an atomic reaction would not be possible, and even if they were, there is almost no chance that the reaction could proceed if the device was being broken apart by the kinetic energy of some external blast.
