While the battle was raging Grant's general demeanor was imperturbable. He remained with Meade nearly the whole day at headquarters at the Lacy house. He sat upon a stump most of the time, or at the foot of a tree, leaning against its trunk, whittling sticks with his pocket-knife and smoking big black cigars--twenty during the day. He received reports of the progress of the battle and gave orders without the least evidence of excitement or emotion. "His orders," said one of his staff, "were given with a spur," implying instant action. On one occasion, when an officer, in great excitement, brought him the report of Hancock's misfortune and expressed apprehension as to Lee's purpose, Grant exclaimed with some warmth: "Oh, I am heartily tired of hearing what Lee is going to do. Go back to your command and try to think what we are going to do ourselves." Several brigades of Longstreet's troops, though weary from their forced march, were sent on a flanking movement against Hancock's left, which demoralized Mott's division and caused it to fall back three-quarters of a mile. Longstreet now advanced with the rest of his corps. The dashing leader, while riding with Generals Kershaw and Jenkins at the head of Jenkins' brigade on the right of the Southern battle array, was screened by the tangled thickets from the view of his own troops, flushed with the success of brilliant flank movement. Suddenly the passing column was seen indistinctly through an opening and a volley burst forth and struck the officers. When the smoke lifted Longstreet and Jenkins were down--the former seriously wounded, and the latter killed outright. As at Chancellorsville a year before and on the same battle-ground, a great captain of the Confederacy was shot down by his own men, and by accident, at the crisis of a battle. Jackson lingered several days after Chancellorsville, while Longstreet recovered and lived to fight for the Confederacy till the surrender at Appomattox. General Wadsworth, of Hancock's corps, was mortally wounded during the day, while making a daring assault on the Confederate works, at the head of his men.
