Quotations
No matter where they were billeted, the staff officers' reality was unchanging: a dozen telephone numbers, some signals corps pilots and motorcyclists, a signals officer, a teleprinter, a message despatch point, a radio and—laid out on the table—a map of the war, densely covered with blue and red pencil marks.
