One of the machine gunners was holding a hurt wrist from that awkward descent. He kept feeding ammunition into the gun for his partner to fire, though. All six machine guns, even the pair in the rear, were blazing away now, making things lively for any Confederate soldiers unlucky enough to be nearby.
“Keep moving!” Morrell shouted to the driver. “We’ve got to keep moving.” The young fellow at the barrel’s complicated controls raised both eyebrows to show he didn’t understand. Straight, Morrell signaled resignedly. But he couldn’t keep from talking, even if he couldn’t hear himself, let alone make anyone else hear: “We’ve got to keep driving them. If we hit them hard enough now, we can crack this line, and if we crack this line, Nashville isn’t worth anything to them any more, because we’ll shell it flat.”
Left, he signaled the driver, waggling his hand to show he didn’t need a whole lot of left. He saw a way over the next trench line, one not quite so drastic as the barrel had used in its first descent. They went down a ways, they came back up, and the machine guns kept hammering.
He wondered how the rest of the barrels were doing, and the U.S. infantry moving forward with and after them. He couldn’t tell, not stuck inside the way he was. Wireless telegraph, he thought. We need barrels with wireless telegraph sets inside, so we can keep track of what’s going on all over the field. He shrugged. If it didn’t happen in this war, it would in the next, whenever that came along.
Meanwhile, he realized he did have a way to find out what was going on around him. He undogged the roof hatch, threw it open, stood up, and looked ahead and to the rear. “Bully,” he said softly. “Oh, bully.”
A few of the barrels had bogged down in trenches and shell holes. Others had taken hits from artillery or were otherwise disabled, some pouring pillars of greasy black smoke into the sky to mark their pyres. But most, like his, were still rumbling forward-rumbling forward and driving all before them.
The artillerymen fired the barrel’s nose cannon. Out here in the open air, the noise was terrific, like a clap of doom. The high-explosive shell exploded in front of a knot of Confederate soldiers and knocked them flying. Some, Morrell saw, were colored men. That confirmed intelligence reports. The shell didn’t care. It did its damage most impartially.
He took another look over his shoulder, and pumped a fist in the air in delight. In the wake of the barrels, and coming up even with the slower ones, were infantrymen in green-gray, swarming forward and out to the flanks to take possession of the ground the barrels cleared.
Not all the Confederate troops, white or Negro, were breaking. Morrell rapidly discovered that, while standing up so his head and torso were out of the barrel gave him a far better view of the field than he could have had inside the machine, it also made him a far better target. Bullets cracked past his head. Others clanged and ricocheted off the cupola with assorted metallic sounds of fury.
After half a minute or so, he decided he’d be tempting fate if he stayed out there any longer. He ducked back into the infernal gloom and fumes inside the barrel, and slammed the hatch shut after him. The driver and the rest of the crew stared at him as if convinced he’d gone utterly mad. His grin was compounded of excitement and triumph. He stuck up a thumb to show how things were going on the battlefield as a whole, then signaled to the driver. Straight, his hands said. The driver, eyes wide, saluted before pressing on.
The crew cheered loud enough to be heard over the roar and rumble of engines, tracks, and guns.
How far had they come? Morrell was sure they’d made better than a mile, maybe even a mile and a half, and noon was-he checked his watch-still more than an hour away. If they could keep it up, they’d have a hole miles wide and three or four miles deep torn in the Confederate line by the time the sun set on this most spectacular Remembrance Day of all time.
“Keep going,” he muttered. “We’ve got to keep going.”
Plenty of men in butternut were inclined to disagree with him. The C.S. soldiers defending the line above Nashville understood its importance every bit as well as did the U.S. attackers. The roar off to his left was a barrel taking a direct hit from a shell. Another shell struck in front of his own machine, showering the armored chassis with fragments and lumps of earth.
Speed up, he signaled the driver, and the barrel rattled forward. As if he were in an aeroplane, he went through random right and left turns to throw off the enemy gunners’ aim. Hitting a moving, dodging target was not something the crews of field pieces practiced. Shells burst near the barrel, but none hit. This was not like shelling infantrymen: a miss, here, was as good as a mile.
One of the two artillerymen at the nose cannon waved to him and pointed. He nodded, then signaled the driver to halt. They fired their gun once, twice in quick succession. Peering through his louvers, Morrell watched men tumble away from the carriage of one of the CSA’s nasty three-inch guns. They did not get up again. Straight, he signaled the driver.
A moment later, he caught sight of another barrel, a little off to the right and several hundred yards ahead. He snarled something he was glad no one else could hear. He thought he’d been one of the leaders of this assault. How had that other bastard got so far ahead of him? He was green with jealousy, greener than his uniform.
Then he took another, longer, look. Jealousy faded, replaced by hot anticipation. That wasn’t a U.S. barrel-it was one of the rhomboids the CSA built, copying the design from the British. Barrels had seldom met other barrels in combat. His mouth stretched wide in a grin. A new encounter was going onto the list.
He got the driver’s attention, then pointed southwest till the fellow spotted the Confederate barrel- tanks, the Rebels sometimes called them, which struck Morrell as a silly name. He clenched his fist to show the driver he wanted to engage the enemy machine. The youngster nodded and turned toward it.
The Confederate barrel had spotted him, too, and began making a ponderous turn of its own to bring both its sponson-mounted cannon to bear on him. Since neither machine could move at anything much above a walking pace, the engagement developed with the leisure, though hardly with the grace, of two sailing ships of the line.
Flame burst from the muzzle of one of the Confederate barrel’s guns. Uselessly, Morrell braced himself for the impact of the shell. It missed. The artillerymen waved to him. He signaled the driver to halt. They fired. They missed, too. Straight, he signaled the driver. Speed up.
Perhaps unnerved by his lumbering charge, the crew of the Confederate barrel’s other cannon also missed their shot. His own gunners waved again. The barrel halted. They fired. Smoke and flame spurted from the enemy. “Hit!” Morrell screamed. “We got him!” Hatches on the sides and top of the Confederate machine flew open. The crew began bailing out. Morrell swung his own barrel sideways, so his machine gunners could give them a broadside.
And then the command was Straight again. He stood up once more to look around, this time for only a moment. Fewer U.S. barrels were near than before. More had been hit or bogged down or broken down. But the survivors-and there were many-still advanced, and the U.S. infantry with them.
Maybe they would go on all the way to the Cumberland. Maybe the Confederates, with the advantage of moving on un-wrecked ground, would patch together some kind of line and halt them short of the river. In a way, it hardly mattered. The big U.S. guns would move forward, miles forward. From their new position, they’d pound Nashville to pieces.
“Breakthrough,” Irving Morrell said, and ducked down into the barrel again.
Gas shells didn’t sound quite like shrapnel or high explosive. They gurgled as they flew through the air, and burst with a report different from those of other rounds. “Get your gas helmets on!” Sergeant Jake Featherston screamed as the shells began raining down around the guns of his battery.
