"The enemy captured seven of our guns on Sunday, but on Monday we recovered seven--not the identical guns we had lost, but enough in number to balance the amount. At the time of recovering our camps, our men were so fatigued that we could not follow the retreating masses of the enemy; but on the following day, I followed up with Buckland's and Hildebrand's Brigades for six miles, the result of which I have already reported. Of my personal staff, I can only speak with praise and thanks. I think they smelt as much gunpowder and heard as many cannon-balls and bullets as must satisfy their ambition. Captain Harmon, my Chief of Staff, though in feeble health, was very active in rallying broken troops, encouraging the steadfast, and aiding to form the lines of defence and attack. I commend him to your notice. Major Sanger's intelligence, quick perception and rapid execution, were of very great value to me, especially in bringing into line the batteries that co-operated so efficiently in our movements. Captains McCoy and Dayton, Aids-de-Camp, were with me all the time, carrying orders and acting with coolness, spirit and courage. "To Surgeon Hartshorn and Doctor L'Hommedieu, hundreds of wounded men are indebted for the kind and excellent treatment received on the field of battle, and in the various temporary hospitals created along the line of our operations. They worked day and night, and did not rest till all the wounded of our own troops, as well as of the enemy, were in safe and comfortable shelter. To Major Taylor, Chief of Artillery, I feel under deep obligations for his good sense and judgment in managing the batteries on which so much depended. I enclose his report and endorse his recommendations. The cavalry of my command kept to the rear and took little part in the action, but it would have been madness to have exposed horses to the musketry fire under which we were compelled to remain, from Sunday at 8 A. M., till Monday at 4 P. M. Captain Kossack, of the Engineers, was with me all the time, and was of great assistance. I enclose his sketch of the battle-field, which is the best I have seen, and which will enable you to see the various positions occupied by my division, as well as of the others that participated in the battle." Said General Grant in his official report: "It becomes my duty again to report another battle fought between two great armies, one contending for the maintenance of the best Government ever devised, and the other for its destruction. It is pleasant to record the success of the army contending for the former principle. "On Sunday morning our pickets were attacked and driven in by the enemy. Immediately the five divisions stationed at this place were drawn up in line of battle to meet them. The battle soon waxed warm on the left and centre, varying at times to all parts of the line. There was the most continuous firing of musketry and artillery ever heard on this Continent, kept up until nightfall.
