[from the diary of Samuel Johnson, 1st Massachusetts Independent Light Battery]

              May 13th

Lay still all day yesterday.  Were turned out
at three A. M. harnessed and packed up,
and by five were once more on the tramp.
At 12. M we arrived at Cumberland
and encamped on a hundred acre
corn field.  This place is the Head Qrs.
of Gen McClellan.  Quite a number of
prisoners are being brought in, or give them-
-selves up voluntarily.  there are 1300 in one
camp.  Very warm and pleasant.
