General Grant to General Cullum.
Headquarters, District of West Tennessee,
Fort Donelson, February 16th, 1862.
To
Brigadier-General George W. Cullum,
Chief of Staff, Department of the Missouri.
General: I am pleased to announce to you the unconditional surrender, this morning, of Fort Donelson, with twelve to fifteen thousand prisoners, at least forty pieces of artillery, and a large amount of stores, horses, mules, and other public property.
I left Fort Henry on the 12th instant, with a force of about fifteen thousand men, divided into two divisions, under the command of Generals McClernand and Smith. Six regiments were sent around by water the day before, convoyed by a gunboat (or boats), and with instructions not to pass it.
The troops made the march in good order, the head of the column arriving within two miles of the fort at twelve o'clock, m. At this point the enemy's pickets were met and driven in. The fortifications of the enemy were from this point gradually approached and surrounded, with occasional skirmishing on the line. The following day, owing to the non-arrival of the gunboats and re-enforcements sent by water, no attack was made, but the investment was extended on the flanks of the enemy, and drawn closer to his works, with skirmishing all day. On the evening of the 13th, the gunboats and re-enforcements arrived. On the 14th a gallant attack was made by flag-officer Foote upon the enemy's river batteries with his fleet.
The engagement lasted probably one hour and a half, and bid fair to result favorably, when two unlucky shots disabled two of the armed boats, so that they were carried back by the current. The remaining two were very much disabled also, having received a number of heavy shots about the pilot-houses and other parts of the vessels. After these mishaps, I concluded to make the investment of Fort Donelson as perfect as possible, and partially fortify, and await repairs to the gunboats. This plan was frustrated, however, by the enemy making a most vigorous attack upon our right wing, commanded by Brigadier-General J. A. McClernand, and which consisted of his division and a portion of the force under General L. Wallace.
The enemy were repelled, after a closely contested battle of several hours, in which our loss was heavy. The officers suffered out of proportion. I have not the means of determining our loss, even approximately, but it cannot fall far short of twelve hundred killed, wounded and missing. I shall retain here enough of the enemy to exchange for them, as they were immediately shipped off, and not left for recapture.
About the close of this action the ammunition and cartridge boxes gave out, which, with the loss of many of the field officers, produced great confusion in the ranks. Seeing that the enemy did not take advantage of it, convinced me that equal confusion, and, consequently, great demoralization existed with him. Taking advantage of this fact, I ordered a charge upon our left (enemy's right) with the division under General C. F. Smith, which was most brilliantly executed, and gave to our arms full assurance of victory. The battle lasted until dark, and gave us possession of part of the intrenchment. An attack was ordered from the flank after the charge by General Smith was commenced, by the divisions under McClernand and Wallace, which, notwithstanding hours of exposure to a heavy fire in the fore part of the day, was gallantly made, and the enemy further repulsed. At the points thus gained, night having come on, all the troops encamped for the night, feeling that a complete victory would crown their efforts at an early hour in the morning. This morning, at a very early hour, a note was received from General Buckner, under a flag of truce, proposing an armistice. A copy of the correspondence which ensued is herewith enclosed.
I could mention individuals who especially distinguished themselves, but will leave this to division and brigade commanders, whose reports will be forwarded as soon as received.
