figure out how part of a logfile got deleted

I there a way to figure out how part of a logfile got deleted? I know unix does not have a date created date so that makes things very difficult to tell if the file got deleted or not. Several thousand lines of my .bash_history somehow got deleted. I still have this in my .bashrc so I don't understand what happened.

Code:
HISTSIZE=9000
