You’re not alone at all. In fact, inspired by you, while trying to locate exactly what makes this chapter so poignant, I gave some more thought to the character of old Prince Bolkonsky. He seems, after all, to be the character most suffering. I added some stuff to the essay but I’ll share it here as well:
The old Prince rages, unable to accept what has happened. I think his major problem is that nearly all his striving is an attempt to impose order on a decidedly disordered world. His strict routines, his habits are all continuously upset by an indifferent, chaotic cosmos.
