Lee, with Hill and Longstreet, had recently ridden along the lines followed by the older staff officers, and often shells and the bullets of sharpshooters had struck about them, but they remained unhurt. Now Lee stopped at one of his old points of observation. It was now about one o'clock in the afternoon, and as the last gun took its place the whole artillery of the Southern army opened with a fire so tremendous that Harry felt the earth trembling, and he was compelled to put his fingers in his ears lest he be deafened.
A storm of metal flew across the valley toward the Northern ranks, but the guns there did not reply yet. The Union troops lay close behind their intrenchments and mostly the storm beat itself to pieces on the side of the hill. The smoke soon became so great that Harry could not tell even with glasses what was going on in the enemy's ranks, but he inferred from the fact that they were not yet replying that they were not suffering much.
But in a quarter of an hour the tremendous cannonade was suddenly doubled in volume. The Union guns were now answering. Two hundred cannon facing one another across the valley were fighting the most terrible artillery duel ever known in America. The air was filled with shells, shot, grape, shrapnel, canister and every form of deadly missile.
Harry and Dalton sprang to cover, as some of the shells struck about them, but they stood up again when they saw that Lee was talking calmly with his generals.
The Southern fire was accurate. General Meade's headquarters were riddled. Many important officers were wounded, but the Northern gunners, superb always, never flinched from their guns. They fell fast, but others took their places. Guns were dismounted but those in the reserve were brought up instead.
The appalling tumult increased. The shells shrieked as they flew through the air in hundreds, and shrapnel and grape whined incessantly. Harry thought it in very truth the valley of destruction, and it was a relief to him when he received an order to carry and could turn away for a little while. He saw now in the rear the brigades of Pickett which were forming up for the charge, about four thousand five hundred men who had not yet been in the battle, while nearly ten thousand more, under Trimble, Pettigrew and Wilcox, were ready to march on their flanks. Pickett's men were lying on their arms patiently waiting. The time had not quite come.
When Harry came back from his errand the cannonade was still at its height. The roar was continuous, deafening, shaking the earth all the time. A light wind blew the smoke back on the Southern position, but it helped, concealing their batteries to a certain extent, while those of the North remained uncovered.
The Northern army was now suffering terribly, although its infantry stood unflinching under the fire. But the South was suffering too. Guns were shattered, and the deadly rain of missiles carried destruction into the waiting regiments. Harry saw Lee and Longstreet continually under the Union fire. They visited the batteries and encouraged the men. Showers of shells struck around them, but they went on unharmed. Wherever Lee appeared the tremendous cheering could be heard amid the roar of the guns.
Now the Southern artillerymen saw that their ammunition was diminishing fast. Such a furious and rapid fire could not be carried on much longer, and Lee sent the word to Pickett to charge. Harry stood by when the men of Pickett arose—but not all of them. Some had been struck by the shells as they lay on the ground and had died in silence, but their comrades marched out in splendid array, and a vast shout arose from the Southern army as they strove straight into the valley of death.
Harry shouted with the rest. He was wild with excitement. Every nerve in him tingled, and once more the black specks danced before his eyes in myriads. Peace or war! Right or wrong! He was always glad that he saw Pickett's charge, the charge that dimmed all other charges in history, the most magnificent proof of man's courage and ability to walk straight into the jaws of death.
