''* Note: There is an apparent time discrepency in the continuity of the book as to the exact times. Chapter 19 begins at 600 hours while Chapter 20 begins at 1800, and it seems as though there is no significant lapse of time between them. Chapter 22 Begins at 2010 Hours and then Chapter 23 begins at 0500 hours, yet they all claim to have happened on July 17.'' This may have been a typo, and Chapter 23 was meant to be July 18.
