“They arrived at Gen. Rosenfelt's headquarters (which were with his army) and reported. Gen. Rosenfelt was very glad to see the General, and told him that he would assign him to the command of a first-class division under Gen. Papson, his army then being divided into three full corps, commanded respectively by Papson, Gen. Critsinger and Gen. McCabe. His army numbered, embracing all arms of the service, some 56,000 effective men, and was well supplied with all necessary material for any kind of movement. “On the next morning Gen. Anderson was assigned to the command of such a division as mentioned. He was well pleased with his corps commander, who was a fine-looking man of middle age, very quiet and unostentatious. The whole army seemed to be in splendid condition for a campaign. On looking through his division that day he found Stephen Lyon in command of his Third brigade, and Peter in command of one of Stephen's regiments. This delighted the General, and he quickly said to Capt. Jackson: “'Gen. Rosenfelt and Gen. Papson both being old friends of Uncle Daniel, I suspect one of his letters might be found amongst the papers of both Rosenfelt and Papson.' “'Capt. Jackson laughed and said: “'Well, father has nothing else to do except to keep the President posted and look after his children, which he faithfully does.' “'Yes,' said Gen. Anderson; 'he does his duty in all respects.' “That afternoon Gen. Stephen Lyon and Col. Peter Lyon (being their respective rank at that time) visited Gen. Anderson's headquarters, and of course enjoyed themselves, each thanking the good fortune that had brought them together. They discussed the situation, and Stephen was decidedly of the opinion that unless we advanced at once and gave battle that the enemy would do so, and the position we occupied not being a favorable one for defense, he thought we could force a battle where our position would be better. “The enemy at this time were also in good condition, and were commanded by Gen. Biggs, with three full corps, commanded respectively by Gen. Polkhorn, Gen. Chatham and Gen. Harding. Biggs's command was disposed as follows: Polkhorn's corps and three brigades of Harding's were at Murphy's Hill; the remainder of Harding's corps to the southwest some twenty miles, forming the left flank; the remainder of Biggs's army lay some twenty miles to the south and east; on and in advance of his extreme left was one division on the Nashua and Franktown road. In this position lay the rebel army, in easy supporting distance to the center and main line, it having been selected by Biggs as a good position on which to make his stand against.our forces, his outposts being ordered to fall back should our forces advance. The position was a good one, as it forced our army to cross Stone Run in his front in any direction that our troops might approach him.
