of Nashville, and every foot of the way, especially the many
bridges, trestles, and culverts, had to be strongly guarded against
the acts of a local hostile population and of the enemy's cavalry.
Then, of course, as we advanced into Georgia, it was manifest that
we should have to repair the railroad, use it, and guard it
likewise: General Thomas's army was much the largest of the three,
was best provided, and contained the best corps of engineers,
railroad managers, and repair parties, as well as the best body of
spies and provost-marshals. On him we were therefore compelled in a
great measure to rely for these most useful branches of service. He
had so long exercised absolute command and control over the railroads
in his department, that the other armies were jealous, and these
thought the Army of the Cumberland got the lion's share of the
supplies and other advantages of the railroads. I found a good deal
of feeling in the Army of the Tennessee on this score, and therefore
took supreme control of the roads myself, placed all the army
commanders on an equal footing, and gave to each the same control, so
far as orders of transportation for men and stores were concerned.
Thomas's spies brought him frequent and accurate reports of Jos. E.
Johnston's army at Dalton, giving its strength anywhere between forty
and fifty thousand men, and these were being reenforced by troops
from Mississippi, and by the Georgia militia, under General G. W.
Smith. General Johnston seemed to be acting purely on the defensive,
so that we had time and leisure to take all our measures deliberately

readiness for the grand forward movement, and then returned to
Nashville; General Schofield going back to Knoxville, and McPherson
to Huntsville, Thomas remaining at Chattanooga.

On the 2d of April, at Nashville, I wrote to General Grant, then at
