eleven
o'clock
All night long their signal torches were working upon the mountain and hilltops . The Southern commander , General Bragg , evidently considered Lookout Mountain impregnable , and withdrew many troops from that point , concentrating them upon his extreme right , in anticipation of Sherman 's attack . `` Lookout was enveloped in dense fog the first part of the following day , which enabled Hooker to dispose of his troops from that point as he desired , preparatory for attack , with little or no opposition . At eleven o'clock the fog began to lift , the attack commenced , and to us below was unveiled one of the grandest , most soul-stirring exhibition of courage and love of country ever witnessed ! Thousands of blue-coated boys pressed their way up the steep slopes of this mighty mountain , in spite of the desperate resistance of a foe well worthy of their steel . Well might we below raise a great shout of exultation and sympathy . The guns of Wood and adjacent forts thundered out salvos of praise and encouragement .
