It devolves upon you, general, to take the initiative in the forward movement of this grand army; and on you and your noble command must depend, in a great measure, the extent and brilliancy of our success. Bear in mind that celerity, audacity, and resolution are every thing in war, and especially is it the case with the command you have, and the enterprise on which you are about to embark.
Very respectfully, your obedient servant,
S. WILLIAMS,
Assistant Adjutant-General.
In pursuance of which order, the corps broke camp near Belle-Plain, and encamped on the evening of April 13, beyond Morrisville. On April 14, it moved down to the vicinity of the bridge at Rappahannock station, which, after a slight skirmish by Gregg, was taken possession of. Beverly Ford, some miles above, was also examined, and the north bank occupied. Preparations for an early move on the morning of the 14th were made. Gen. Buford, commanding the cavalry reserve, remained at Kelly's Ford during the 14th, in order to draw the attention of the Confederates to that point, and indulged in a little artillery skirmish.
During the night a heavy rain set in, and before morning the river was no longer fordable by the artillery and pack-trains.
As is well known, it takes no great rainfall to swell the Rappahannock and Rapidan rivers, and their tributaries, to the proportion of torrents. Nor are more than a few hours necessary to raise these rivers and runs, and even the dry ravines, to an impassable depth. Gregg mentions in his report that a small stream, which, on the 13th, could be crossed at one step, had swelled to such a flood, that when, on the 15th, a regiment was obliged to cross it, there were lost one man and two horses by drowning.
So that, after crossing one division, Stoneman found that it would probably be isolated on account of the impracticability of crossing the rest of the corps, and consequently ordered its immediate return. And this was accomplished none too soon, by swimming the horses.
On reporting all these facts to Hooker, Stoneman was ordered to go into camp, where he remained, along the Orange and Alexandria Railroad, until the 27th.
The following letter is of interest, in this connection, as showing how keen Mr. Lincoln's intuitions occasionally were.
EXECUTIVE MANSION,
WASHINGTON, D.C., April 15, 1863.
MAJOR-GEN. HOOKER.
It is now 10.15 P.M. An hour ago I received your letter of this morning, and a few moments later your despatch of this evening. The latter gives me considerable uneasiness. The rain and mud, of course, were to be calculated upon. Gen. S. is not moving rapidly enough to make the expedition come to anything. He has now been out three days, two of which were unusually fair weather, and all three without hinderance from the enemy, and yet he is not twenty-five miles from where he started. To reach his point he still has sixty to go, another river (the Rapidan) to cross; and will he be hindered by the enemy? By arithmetic, how many days will it take him to do it? I do not know that any better can be done, but I greatly fear it is another failure already. Write me often. I am very anxious.
