Letter From Lieut. Jobe.

March 2d, 1862.

DEAR COLONEL: Since we left Paducah our regiment has been moving form place to place, and we have been exposed most of the time to the open air, having no tents or facilities for writing, or I should have written to you long ere this. Many have been the changes since I last wrote to you, and many brave sons of the north have passed from time to eternity, having fallen upon the battle-field by the hand of a southern foe; and many a rebel has also been consigned to his final resting place, which should justly be the fate of every man who would take up arms to battle against so righteous a cause as that in which we are now engaged. It is needless for me to enter into a detail of what has taken place since we left Paducah — of that the telegraph has informed you long ago, but I might mention a few things which may prove interesting and which are not given by newspaper reporters. Suffice it to say that Fort Henry was taken by the gunboats without any assistance from the land forces, although we were on hand, willing to "pitch in" when ordered to do so. From Fort Henry we marched across the country to Fort Donelson, a distance of about twelve miles, where we had the honor of participating in one of the hardest fought battles ever recorded in the history of our country. We lay outside the fort for three successive days and nights, without blankets, tents or fires, and the weather was extremely cold, there being abundance of rain, sleet and snow. Our provisions also were short, we having to live on half rations part of the time, and the day before the surrender the men went into the field early in the morning without a mouthful of provisions in their haversacks, where they remained until sundown, not receiving anything to eat until after dark. The first two days the fighting was not general, principally skirmishing, Birge's sharp-shooters doing good execution. Saturday, the day before the surrender, the fighting was general, and continued without cessation during the whole day. Early in the morning, before the men had time to prepare their scanty breakfast, the rebels fired on the pickets upon our fight flank, it evidently being their intention to cut their way out, as those of the rebels who were killed in the unsuccessful attempt had about three days' rations in their haversacks, and their knapsacks on, containing all their clothing. The first brigade was on the right flank, the 9th, 12th and 41st Illinois regiments, and, in half an hour after the pickets of the 9th were fired on, our regiment was in the thickest of the fight, and we held our position for about an hour and a half, when we were compelled to fall back, it being impossible to hold our position any longer against such odds, we failing, from some cause or other, to receive any reinforcements. Companies A. and B. were sent out as skirmishers, and suffered severely. Company C. took position in an old building near by, and also suffered terribly, the enemy shooting almost every man who approached the windows to fire. Company D. was ordered to a fence a few paces in advance of the regiment, where, opposed to a raking fire, they fought bravely and manfully until ordered to retire. The left wing of the regiment was kept in reserve, and did not take any active part in the engagement. Our company was very fortunate, we only having five wounded and one missing. The names of the wounded are as follows: Elisha M. Divinney, in the leg; Geo. Bruner, in the thigh; Alonzo Lewis, in the arm; Andrew McGinnis, in the side; Theodore Simmons, in the arm; Martin V. Allen, missing. The number of killed, in our regiment, is represented at 35, and 120 wounded. I have not yet ascertained the exact number. I don't think the number of wounded is quite so great.

Whilst we were engaged on the right flank, The 2d Iowa regiment did good execution on the left. With Gen. Smith at their head, they made a gallant and fearful charge upon one of the enemy's principal breastworks, up a steep and rugged hill, rendered still more difficult by the fallen timber. They routed the enemy from their stronghold; they could not stand our glittering steel, and made a disorderly retreat for their main fort, the Iowa boys dealing a deadly fire into them as they fled. The 2d Iowa lost a considerable number of men in the charge. With the exception of their bold and daring charge, for which the Iowa boys deserve great credit, the principal part of the fighting was done by Illinois troops. After we had got possession of this breastwork, the battle ceased for the day, Saturday evening, February 15th.

The next morning at day break, (Sunday,) a flag of truce was seen floating from the enemy's main fort. A messenger was dispatched from the fort to Gen. Grant, to the effect that Gen. Buckner wished an interview with him. Pillow and Floyd made their escape on Saturday night. The interview was held, and Gen. Buckner wished to made a conditional surrender, the conditions being the evacuation of the fort with his troops and arms. That did not exactly meet the approbation of Gen. Grant, his terms being an unconditional surrender, and he gave the gentleman fifteen minutes to make up his mind, stating that at the end of that time, if he did not surrender, he intended to commence operations, as the troops were all very anxious to get into the fort. Gen. Grant left him, and had scarcely arrived at the breastwork where our batteries were planted, and ordered every gunner to his post, before a messenger, bearing a flag of truce, conveyed the intelligence to him that Gen. Buckner had come to the conclusion to make an unconditional surrender. Our troops poured into the fort from all quarters, the bands played national airs, and were an hour before floated the rebel rag, now floated triumphantly the star-spangled banner.

After getting into the fort I had the pleasure of taking by the hand many Rock Islanders. Rock Island county was well represented in the fight. Capt. Gregg's "Fighting Irish" company, Capt. Hawley's company, Capt. Conklin's sharp shooters, Capt. Dodge's cavalry company, and company D, 12th Ill., were all there.

There are many items of interest which occurred upon the battle-field and which I might mention, but they would occupy too much space in your columns, and, in fact, the subject of this letter has become so old, and our mail arrangements are so irregular, that it may be some time before you receive what I have already written.

Our regiment has been to Nashville, and returned to Clarksville, where we are now stationed, but for how long a time I cannot tell. No rebel troops at Nashville — all having retreated.

I received an ARGUS yesterday, which has only been one month on the way. I received your circular yesterday, and will furnish you with a descriptive roll of our company as soon as I can arrange it.

Hoping that you will excuse me for not having written sooner, I subscribe myself

Yours, respectfully,
