To a man like General Grant, simple minded and sincere, a man whose sole ambition was to force the war to a successful conclusion within the briefest possible time, and whose vigor in action seemed to make that result certain with the masterful means now in hand at Pittsburg Landing, this foolish frittering away of the opportunity he had created by his splendid fighting, must have been the most painful of all the punishments which Halleck at that time inflicted upon him for his impertinence in wresting a great victory from a calamitous defeat, before his superior officer could reach the field and reap the credit for himself. But Halleck had other humiliations in store for his impertinently successful lieutenant the late Galena clerk, and the now admired and applauded officer of volunteers. Grant even yet had no rank in the regular army, and he had ventured to advise the temporary dissolution of the regular army in order that the skill and training of its officers might be utilized--with capacity alone as the test--in making the volunteers, who after all constituted the country's chief reliance for its salvation, as effective in the field as if they had been regulars. We have seen how, after Grant's conquest of Forts Henry and Donelson, and the complete rupture of the first Confederate line of defense, Halleck forbade him to gather the fruits of his victory, suspended him from command and seemingly threatened him with arrest. After Shiloh it would not have been prudent for Halleck again to suggest the arrest of a general whose name was on every lip as that of the one Federal commander who was capable of winning victories while all others were meeting conspicuous defeats. But Halleck had other arrows in his quiver. He left Grant as nominally his second in command, and, in form at least, assigned him specifically to the command of the right wing of the army. But he proceeded from the beginning to ignore his second in command. He summoned him to none of those councils and consultations to which he invited Grant's own subordinates. Even in the matter of orders to that wing of the army which he had technically placed in Grant's charge, he ignored all the courtesies and flagrantly violated all the usages of war, by sending his commands directly to division generals, instead of sending them through General Grant's headquarters--thus rivaling the discourtesy of Judah P. Benjamin in his dealings with Stonewall Jackson. This left Grant in humiliating ignorance even of the orders issued to divisions which were supposed to be under his command, and for whose movements and conduct he was held responsible. His situation was unendurable, even to a man of his robust habits of mind, and by way of relief he finally asked permission to establish his headquarters as District Commander, at Memphis, a city which had by that time come into Federal control.
