the whole new Rebel line opens a hot fire upon Burnside's Brigade.

Hunter, for the purpose of better directing the Union attack, is at this
moment rapidly riding to the left of the Union line,--which is advancing
Southwardly, at right angles to Bull Run stream and the old line of
Rebel defense thereon. He is struck by the fragment of a shell, and

regiments of the Enemy.

The regiments of Burnside's Brigade are getting considerably cut up.
Colonels Slocum and Marston, and Major Balch, are wounded. There is
some confusion in the ranks, and the Rhode Island Battery is in danger

Burnside's rallied regiments, and the opening artillery practice of
