The Era of Civil War: Rapidan and Rappahannock
I therefore determined, first, to use the greatest number of troops practicable against the armed force of the enemy; preventing him from using the same force at different seasons against first one and then another of our armies, and the possibility of repose for refitting and producing the necessary supplies for carrying on resistance. Second, to hammer continuously against the armed force of the enemy and his resources, until by mere attrition, if in no other way, there should be nothing left to him but an equal submission with the loyal section of our common country to the constitution and laws of the land.
These views have been kept constantly in mind, and orders given and campaigns made to carry them out. Whether they might have been better in conception and execution is for the people, who mourn the loss of friends fallen, and who have to pay the pecuniary cost, to say. All I can say is, that what I have done has been done conscientiously, to the best of my ability, and in what I conceived to be for the best interests of the whole country.
After detailing the instructions given to his officers, and sketching the disposition of General Lee's forces, Grant proceeds with his narrative.
The movement of the Army of the Potomac commenced early on the morning of the 4th of May, under the immediate direction and orders of Major-General Meade, pursuant to instructions. Before night, the whole army was across the Rapidan (the fifth and sixth corps crossing at Germania Ford, and the second corps at Ely's Ford, the cavalry, under Major-General Sheridan, moving in advance), with the greater part of its trains, numbering about four thousand wagons, meeting with but slight opposition. The average distance travelled by these troops per day was about twelve miles. This I regarded as a great success, and it removed from my mind the most serious apprehensions I had entertained, that of crossing the river in the face of an active, large, well-appointed, and ably commanded army, and how so large a train was to be carried through a hostile country, and protected. Early on the 5th, the advance corps (the fifth, Major-General G. K. Warren commanding) met and engaged the enemy outside his intrenchments near Mine Run. The battle raged furiously all day, the whole army being brought into the fight as fast as the corps could be got upon the field, which, considering the density of the forest, and narrowness of the roads, was done with commendable promptness.
General Burnside, with the ninth corps, was, at the time the Army of the Potomac moved, left with the bulk of his corps at the crossing of the Rappahannock River and Alexandria Railroad, holding the road back to Bull Run, with instructions not to move until he received notice that a crossing of the Rapidan was secured, but to move promptly as soon as such notice was received. This crossing he was apprised of on the afternoon of the 4th. By six o'clock of the morning of the 6th he was leading his corps into action near the Wilderness Tavern, some of his troops having marched a distance of over thirty miles, crossing both the Rappahannock and Rapidan rivers. Considering that a large proportion, probably two-thirds of his command, was composed of new troops, unaccustomed to marches, and carrying the accoutrements of a soldier, this was a remarkable march.
