It must not be forgotten that General Grant was subject to the immediate command of a painstaking plodder who mistook arrogance for dignity and timidity for caution. Halleck's orders contemplated a very different thing from what happened at Donelson. We owe the capture of the fort and the discovery thereby to the world of General Grant, to the treachery of a telegraph operator at Cairo, who, in the belief that he was helping the Southern cause, held up Halleck's order to Grant to "fortify Fort Henry strongly on the land-side," until Grant, in ignorance of it, had gone on and invested Fort Donelson. Had Grant received that order, Donelson and Shiloh and Vicksburg might have had a very different history, and General Grant might not have been known. The fame given him by that one victory was too great even for General Halleck to take away, who did his utmost to do it. With Halleck tying the hands of Grant after his great victory, even to the extent of making groundless charges against him and causing his arrest and with the entire South frantically and hysterically pushing Albert Sidney Johnson forward to a sacrifice, the battle of Shiloh was as much of a logical result as that effect follows cause. Had Grant been given free rein, it could not have been fought; for he would have possessed Corinth before the Confederate armies could have concentrated.
Grant's generalship and brilliant resourcefulness were never shown to better effect than when confronted with that crisis at Donelson. He had depended upon the gun-boats to help reduce the works, run the batteries and take position above. They did severe execution in the fort but in a few hours were helplessly disabled. Grant knew of his own loss but not of that in the fort. At this stage he writes:
"The sun went down on the night of the 14th of February, 1862, leaving the army in front of Fort Donelson anything but comforted over the prospects. The weather had turned intensely cold; the men were without tents and could not keep up fires where most of them had to stay, &c."
It was but natural for him to view the situation in the light of facts as they then appeared and not as he might guess them to be. Had he calculated upon the cowardice rather than the bravery of opposing commanders, he might have provided differently; but it was incredible to him that a fresh army of 21,000 men, within a well provisioned fortress, in direct communication with another army from which it could draw supplies and men, with the Federal gun-boats rendered helpless from its fire, would, at the very outset, without a siege, try to escape from one in an open field, when, by so doing, it was abandoning the key to an immense territory needed for its supplies, breaking, to a large extent, communication between its armies and submitting to lasting disgrace before its own people. That Grant was justified in this view is shown by the fact that the two Confederate Generals, Floyd and Pillow, were, after the surrender, promptly tried and summarily relieved from their commands.
Flag-Officer Foote had been wounded when his flag-ship was disabled and before sunrise on the morning of the 15th, sent for General Grant to call upon him on his flag-ship about four miles below the fort. It was decided that the gun-boats should be sent away for repairs before it would be possible to renew the attack. This, it was estimated, would require about ten days. There was no alternative but a siege.
While leaving the boat, Grant was notified of the severe attack upon our right and of the breaking of our line. He hurried to the scene, about seven miles away. Before knowing the true situation, he gave orders to retire and intrench with a view to a siege. When, however, he learned that the enemy was actually trying to escape, he at once saw its significance and said to Colonel Webster of his staff: "The one who attacks first now will be victorious." Instead of intrenching, he gave orders for an immediate and vigorous attack along the entire left before the enemy, who had withdrawn his forces to our right, could reform. The result was an irresistible onslaught upon the enemy's center and right.
McClernand's men had failed mainly for want of ammunition. Grant gave orders for a supply and for reforming the line. The Confederates waited just long enough to permit this to be done. It subsequently developed that Pillow mistook his partial success for complete victory and stopped to talk about it when he should have been following it up. That he must have been wildly jubilant is indicated by the fact that he telegraphed to Johnson at Nashville, "on the honor of a gentleman," that "the day is ours." A controversy arose between Floyd and Pillow. Pillow, the veteran general, flushed with temporary success, refused to recognize the authority of Floyd, whom he regarded as a civilian, finally took matters into his own hands and ordered Buckner to renew the attack upon our right. Buckner obeyed but it was too late. Our line had been reformed and was ready. A desperate struggle ensued and the enemy was driven back into his works. In the meantime our left wing had pushed forward against the weakened defences upon the enemy's right and bivouacked that night within his lines. The fort was doomed. The famous night council was held by Floyd and his Staff. Before morning dawned Floyd and Pillow were aboard the transports on their way up the river with three thousand men and Forrest, with a thousand men and horses, was struggling in the icy waters of a bayou in a desperate effort to get away. It was one of the ironies of Fate that at about the same time, the authorities at Richmond were rejoicing over Pillow's grandiloquent message announcing Confederate victory.
General Lew Wallace describes Forrest's escape as follows:
"Col. Forrest was present at the council, and when the final resolution was taken he promptly announced that he neither could nor would surrender his command. He assembled his men, all as hardy as himself, and moved out and plunged into a slough formed by back water from the river. An icy crust covered its surface, the wind blew fiercely and the darkness was unrelieved by a star. There was fearful floundering as the command followed him. At length he struck dry land and was safe.
"He was next heard of at Nashville."
