noon
But the Confederate Commander , reinforced now by the arrival of Pickett 's division of fifteen thousand men and Stuart 's cavalry , determined to renew the battle . At the first grey streak of dawn on the 3rd the Federal guns roared their challenge to the Confederate forces which had captured their entrenchments on Culp 's Hill . Seven terrible hours of bombardment , charge and counter charge followed until every foot of space had claimed its toll of dead , before the Confederates yielded the Hill . At noon there was an ominous lull in the battle . At one o'clock a puff of smoke from Seminary Ridge was followed by a dull roar . The signal gun had pealed its call of death to thousands . For two miles along the crest of this Ridge the Confederates had planted one hundred and fifty guns .
