Most soldiers, unless high command, were not apprised of battle plans until they faced their foes on the field, and primitive modes of communication added to the delays in relating information. Rumor, therefore, spread through camp constantly and the men had to try to make sense of it:
June 5, 1863
“Have not started from camp as yet   there
was heavy fighting on our out Post yesterday 
 the enemy attacked us in force
and were repulsed . . .”
June 18, 1863 “. . . The news today is that Lees army is in xxx & Penn & Dix is within fifteen
miles of Richmond supported by the gun Boats but I don’t believe it as yet”
William
Townsend’s 42nd Illinois Infantry participated, as part of the “Army
of the Cumberland,” in the “Tullahoma Campaign.”  Taking place in central Tennessee, the
campaign went on for months: 
Tullahoma Campaign --Following the battle of Stones River (Murfreesboro, TN), the Union and
Confederate forces dug in to prepare for more battle in central Tennessee.  Union Major General Rosecrans and his Army of
the Cumberland camped in Murfreesboro, TN.  Confederate General Bragg and his Army of
Tennessee set up defensive positions to the south in the vicinity of Tullahoma
to guard possible approaches that the Union army might take on its way to
capture the key railroad junction of Chattanooga.  Rosecrans, in no hurry to move during the inclement months of 1863, remained motionless for six months.  Only 30 miles apart, the two armies
waited.  Bragg, however, was overly
confident of his defensive position and the long wait proved disastrous – troop morale dropped from lack of action, and hunger took its
toll.  Bragg also failed to understand
that Rosecrans was methodically preparing for battle.  Once the battle began in June, 1863, it only
took two weeks for Rosecrans to drive Bragg out of middle Tennessee, with the
Union suffering 570 casualties to the Confederate’s 2,000.

The
battles were fierce and the weather miserable at times, hampering supply
trains.  Despite the horrors of war,
Townsend had time to record a beautiful view of a waterfall during a lull in
the fighting.  The following entries from
June 23 through July 4 clearly illustrate the amount of marching and waiting
between actual skirmishes, as well as the taking of prisoners:
| 
 June 23, 1863 “Received orders to
  get ready to march tomorrow morning at 4 Oclock, 12 days rations   don’t know where we are going   Ed & I are going to mess with Co H
  Officers Lt Montgomery & Reynolds as we can not carry a mess chest [chest holding supply of various cooking
  utensils, pots & pans, and food storage cans] unless we double up” June 24, 1863
  “We got up at 4 Oclock am   started for somewhere on Shelbyville
  Pike   had some skirmishing out about 7 miles  while skirmishing with enemy were relieved

            By
the end of July, 1863, rumors still floated about camp and the movement of
troops was uncertain.  During a lull,
sworn enemies put aside their differences for a chat, but for obvious reasons
friendly banter didn’t last:
July
28, 1863 “. . .  the report is that
France is going to recognize the Southern Confederacy but I do not believe it
as of yet”
July
31, 1863 “. . . The Reble Pickets are on the other side of the river   we talk across with them  ask them the price of coffee . . .”
August
4, 1863 “. . . went swimming to night . . . 
Some of the Boys were in day or two ago and got out in the middle of the
river and the Rebs shot at them . . .”
August
16, 1863 “. . . there was a flag of truce crossed the river today   did not hear what it was about”
August
25, 1863 “. . . received news of the fall of Fort Sumter   hope it is so . . .”
September
2, 1863 “Left camp at Bridge just at about 2 Oclock and crossed the river
on the pontoon bridge [a wooden
slat bridge, the deck of which was supported by rows of narrow, wooden
flat-bottomed boats]  marched
around the mountain about three miles and went into camp . . . after we had
crossed the bridge and some of the Battery teams [horse-drawn wagons] were
crossing, the bridge went down so we will have to wait until it is rebuilt for
our things [supplies]”
September
3, 1863 “Slept last night under a bush without a single thing over us   like to have froze to death   our teams did not come up until five Oclock
this Eve. . . .”
September
12, 1863 “Laid in camp all day . . . Rebs can be seen

Our nigger has been sick and we have had to do all our own cooking since
yesterday morning”
            The fighting takes its
toll on the men and camp life.  The
wounded and supply trains have trouble moving about.  Townsend’s birthday comes and goes:
October 3, 1863
“. . .  I went down in town to the
hospital  see some of my men   all
doing well  . . .”
October 5, 1863
