, Louisiana, and Texas was in
the almost undisputed possession of the enemy, with an army of probably
not less than eighty thousand effective men, that could have been
brought into the field had there been sufficient opposition to have
brought them out. The let-alone policy had demoralized this force so
that probably but little more than one-half of it was ever present in
garrison at any one time. But the one-half, or forty thousand men, with
the bands of guerillas scattered through Missouri, Arkansas, and along
the Mississippi River, and the disloyal character of much of the
population, compelled the use of a large number of troops to keep
navigation open on the river, and to protect the loyal people to the
west of it. To the east of the Mississippi we held substantially with
the line of the Tennessee and Holston rivers, running eastward to
include nearly all of the State of Tennessee. South of Chattanooga, a
small foothold had been obtained in Georgia, sufficient to protect East
Tennessee from incursions from the enemy's force at Dalton, Georgia.
West Virginia was substantially within our lines. Virginia, with the
exception of the northern border, the Potomac River, a small area about
the mouth of James River, covered by the troops at Norfolk and Fort
Monroe, and the territory covered by the Army of the Potomac lying along
the Rapidan, was in the possession of the enemy. Along the sea-coast
footholds had been obtained at Plymouth, Washington, and New Bern, in
North Carolina; Beaufort, Folly and Morris Islands, Hilton Head, Fort
Pulaski, and Port Royal, in South Carolina; Fernandina and St.
Augustine, in Florida. Key West and Pensacola were also in our
possession, while all the important ports were blockaded by the navy.
The accompanying map, a copy of which was sent to General Sherman and
other commanders in March, 1864, shows by red lines the territory
occupied by us at the beginning of the rebellion, and at the opening of
the campaign of 1864, while those in blue are the lines which it was
proposed to occupy.
Behind the Union lines there were many bands of guerillas and a large
population disloyal to the government, making it necessary to guard
every foot of road or river used in supplying our armies. In the South,
a reign of military despotism prevailed, which made every man and boy
capable of bearing arms a soldier; and those who could not bear arms in
the field acted as provosts for collecting deserters a
