eight o'clock
At five o'clock in the afternoon while Lee held Hooker 's front , Jackson 's corps crept into position in Hooker 's rear . The shrill note of a bugle rang from the woods and the yelling gray lines of death swept down on their unsuspecting foe . Without support the shattered right wing was crushed , crumpled and rolled back in confusion . At eight o'clock Jackson , pressing forward in the twilight , was mortally wounded by his own men and Stuart took his command . The gay , young cavalier placed himself at the head of Jackson 's corps and charged Hooker 's disorganized army . Waving his black plumed hat above his handsome , bearded face , he chanted with boyish gaiety an improvised battle song : `` Old Joe Hooker , Wo n't you come out o ' the Wilderness ? '' His men swept the field and as Hooker 's army retreated Lee rode to the front to congratulate Stuart .
