During this time it was impossible to determine correctly where General Lee was moving with his main army; but on Monday, the 29th, it became evident that he had selected Gettysburg for his field of operations and on that night the flame of his army’s camp-fires shone luridly against the sky—a warning of the bloody battle to come. During the entire period of this bold invasion of the North the skirmishes, raids, and minor battles consequent upon the continual meetings of the rebel and Union forces were almost daily, but the great battle was that which will ever be remembered at the sound of the word, Gettysburg, and must always bring a glow of pride to the cheek of every loyal American who hears it named. ATTACK ON CARLISLE, PA. JULY 1, 1863. As we have seen, the advance of Lee’s army began on June 27th, a large rebel force occupied the city of Carlisle; and on the 30th they removed all their infantry and stores to Gettysburg. On the evening of July 1st, a severe engagement took place between the rebels under General Fitzhugh Lee (who had not been apprised of the withdrawal of the enemy, under General Ewell, from Carlisle) and the Union forces under command of General W. F. Smith, who were just entering the deserted town. Being unable to comprehend the state of affairs before him General F. H. Lee commenced skirmishing with the Union troops; but finding them much stronger than was supposed, he sent in a flag of truce demanding the surrender of the town. General Smith promptly refused to surrender, and at once made preparations for sending away the women and children. The work of shelling the town was at once commenced; and a perfect shower of grape, canister and shell was poured in upon it for three hours; at the end of that time the enemy’s fire slackened a little, and once more, at midnight, General Lee sent in a flag of truce, with a demand for surrender. General Smith indignantly refused; and the fire of the enemy recommenced, and was carried on without intermission for three hours. During this time severe skirmishing was kept up by the Union infantry, though no heavy reply of artillery was made to the enemy’s fire. Finally the rebels fired the cavalry barracks, and accidentally set on fire several buildings with shells. The town was very much injured and many people were killed, but the rebels were defeated in their object, and obliged to fall back the next day. * * * * *
