War and Peace Volume 4, Part 2, Chapter 15 Summary

As a ploy, Napoleon sends another offer of peace to Kutuzov.
Kutuzov sends a reply basically telling him to kiss his derriere.
Meanwhile, some French troops are spotted near Kutuzov’s army. A detachment under the way-underappreciated and underrated general Dokhturov is sent to check it out.
When Dokhturov and his forces get to the city of Fominskoe, they find not just a few troops, but the whole French army – including Napoleon.
This is big news. A super-fast envoy is sent off to headquarters for instructions.
