The morning of the 29th dawned calm, clear, and beautiful. Sigel obeyed orders. He was on the northwest corner of the old battle-field, near Dogan's house. Jackson was north of the turnpike, his right resting on Bull Run, at Sudley Springs, and his left on the turnpike near Groveton, along the line of an unfinished railway. Schurz was on the right in Sigel's corps, Milroy in the center, Schenck on the left, with Steinwehr in reserve. For an hour there was the deep roll of artillery. Then the line advanced. There was a sharp contest,--Sigel occupying the ground which Jackson held in the first fight on that memorable field, and Jackson upon the ground, where Burnside, Howard, and Hunter formed their lines. Milroy was driven, but Schurz and Schenck held their position. Hooker and Kearny were astir at daylight. They crossed the stream at the Stone Bridge, swung out into the fields, and moved north towards Sudley Springs, forcing Jackson back on Longstreet, who was resting after his hard march, his men eating a hearty meal from the stores captured at Manassas. He was in no condition to fight at that early hour. Time slipped away--precious hours! McDowell had not come. Porter had not been heard from. "Longstreet is getting ready," was the report from the scouts. Noon passed. One o'clock came round. "Longstreet is joining Jackson," was the word from the pickets. The attack must be made at once if ever. It began at two o'clock by Hooker and Kearny on the right, pushing through the woods and across the fields between Dogan's house and Sudley Church.[50] [Footnote 50: See "My Days and Nights on the Battle-Field."] The veterans of the Peninsula move upon an enemy whom they have met before. Jackson has made the line of a half-finished railroad his defense, and his men are behind the embankments and in the excavations. It is a long, desperate conflict. There are charges upon the enemy's lines and repulses. Three,--four,--five o'clock, and Porter has not come. McDowell, who should have marched northwest to Groveton to meet Longstreet, has, through some mistake, marched east of that place, and joined the line where Kearny and Hooker are driving Jackson.
