"A gun cracked, quite close to the tent. Soldier's instinct pulled Lee's head up. Then he smiled and laughed to himself. One of his staff officers, most likely, shooting at a possum or squirrel. He hoped the young man had scored a hit. But no sooner had the smile appeared than it vanished. The report of the gun sounded- odd. It had been an abrupt bark, not a pistol shot or the deeper boom of an Enfield rifle musket. Maybe it was a captured Federal weapon. The gun cracked again and again and again. Each report came closer to the one than two heartbeats were to each other. A Federal weapon indeed, Lee thought: one of those fancy repeaters their cavalry like so well. The fusillade went on and on. He frowned at the waste of precious cartridges- no Southern armory could easily duplicate them. He frowned once more, this time in puzzlement, when silence fell. He had automatically kept track of the number of rounds fired. No Northern rifle he knew was a thirty-shooter. He turned his mind back to the letter to President Davis. -Valley, he wrote. Then gunfire rang out again, an unbelievably rapid stutter of shots, altogether too quick to count and altogether unlike anything he had ever heard. He took off his glasses and set down the pen. Then he put on a hat and got up to see what was going on."
