The Union Army, under command of Maj. Gen U. S. Grant was composed of three divisions of the 13^th, the 15^th and the 17^th Corps.  The Confederates Army, under command of Lieut. Gen. John C. Pemberton, was composed of Stevenson’s, Forney’s, Smith’s and Bowen’s Divisions, and Waul’s Texas Legion.   The two armies were in position on their respective lines as on May 19^th, except that Waul’s Texas Legion had been assigned a position in rear of the left of Lee’s brigade on the left of Stevenson’s Division.   After a heavy cannonade by every gun in position on the Union line, assault’s were made at 10 a.m. by the 15^th corp’s at the Stockade Redan, on the Graveyard Road; by the 17^th Corp’s on the right and left of the Jackson Road; by the 13^th Corp’s at the Lunette on the Baldwin’s Ferry Road, the Railroad Redoubt, and the curtain between that redoubt and Fort Garrott; Hall’s Brigade of McArthur’s Division, 17^th Corp’s, advanced closed to the Confederate line on the Warrenton Road, but did not assault: the colors of the leading regiments were carried close to the confederate works at every point assaulted.   A Brigade Headquarters’ flag was placed on the parapet of the Stockade Redan, flags were placed on the parapet of the Railroad Redoubt and that work was temporarily occupied.  But no permanent lodgment was anywhere made.  Assault’s were made in the afternoon; by the 17^th Corp’s at the curtain between the Railroad Redoubt and the lunette at the Baldwin’s Ferry Road.   At that lunette, at the Jackson Road, and at the curtain north of Glass’ Bayou; and by the 15^th Corp’s at the curtain south of the Graveyard Road, at the Stockade Redan at that road, and at a point about one-third of a mile west of that redan; the colors of the leading regiments were again carried close to the confederate line; another flag was placed on the parapet of the Stockade Redan but the effort to carry the confederate line of defense by assault was unsuccessful at every point.
