Having comprehended the uncertainty of Buell's successful junction with
Grant, Halleck must have received tidings of the final victory at
Pittsburg Landing with emotions of deep satisfaction. To this was now
joined the further gratifying news that the enemy on that same momentous
April 7 had surrendered Island No. 10, together with six or seven
thousand Confederate troops, including three general officers, to the
combined operations of General Pope and Flag-Officer Foote. Full
particulars of these two important victories did not reach Halleck for
several days. Following previous suggestions, Pope and Foote promptly
moved their gunboats and troops down the river to the next Confederate
stronghold, Fort Pillow, where extensive fortifications, aided by an
overflow of the adjacent river banks, indicated strong resistance and
considerable delay. When all the conditions became more fully known,
Halleck at length adopted the resolution, to which he had been strongly
leaning for some time, to take the field himself. About April 10 he
proceeded from St. Louis to Pittsburg Landing, and on the fifteenth
ordered Pope with his army to join him there, which the latter, having
his troops already on transports succeeded in accomplishing by April 22.
Halleck immediately effected a new organization, combining the armies
of the Tennessee, of the Ohio, and of the Mississippi into respectively
his right wing, center, and left wing. He assumed command of the whole
himself, and nominally made Grant second in command. Practically,
however, he left Grant so little authority or work that the latter felt
himself slighted, and asked leave to proceed to another field of duty.

It required but a few weeks to demonstrate that however high were
Halleck's professional acquirements in other respects, he was totally
unfit for a commander in the field. Grant had undoubtedly been careless
in not providing against the enemy's attack at Pittsburg Landing.
Halleck, on the other extreme, was now doubly over-cautious in his march
upon Corinth. From first to last, his campaign resembled a siege. With
over one hundred thousand men under his hand, he moved at a snail's
pace, building roads and breastworks, and consuming more than a
