He would have traded all that fitness for a fat slob's body and an extra armored corps. The Confederates were putting everything they had into this punch. He didn't know what they were up to on the other side of the Appalachians, but he would have been amazed if they could have come up with another effort anywhere close to this one. If this wasn't the Schwerpunkt, everything he thought he knew about what they had was wrong.

His own barrel, with several others, lurked at the edge of the woods east of Chillicothe, Ohio. The Confederates were trying to get around the town in the open space between it and the trees. Morrell spoke into the wireless set that connected him to the others: "Wait till their move develops more fully before you open up on them. That's the way we'll hurt them most, and hurting them is what we've got to do."

"Hurt them, hell, sir," said Sergeant Michael Pound, the gunner. "We've got to smash them."

"That would be nice." Pound was nothing if not confident. He wasn't always right, but he was always sure of himself. He was a stocky, broad-shouldered man with very fair skin and blue eyes. He came from the uppermost Midwest, and had an accent that might almost have been Canadian.

He should have commanded his own barrel. Morrell knew as much. But he didn't want to turn Pound loose. The man was, without a doubt, the best gunner in the Army, and they'd spent a lot of time together in those periods when the Army happened to be interested in barrels. Pound had also done a stretch as an ordinary artilleryman during that long, dreary dry spell when the Army stopped caring that cannon and armor and engine and tracks could go together into one deadly package. Trouble was, the package was also expensive. To the Army, that had come close to proving the kiss of death.

It was, in fact, still liable to prove the kiss of death for a lot of U.S. soldiers. Even though the factories up in Pontiac were going flat out now, they'd started disgracefully late. The CSA had factories, too, in Richmond and Atlanta and Birmingham. They weren't supposed to have been working so long and so hard. But the Confederates were using more barrels than anybody in what was alleged to be U.S. Army Intelligence had suspected they owned.

Here came three of them, a leader and two more behind him making a V. They didn't look much different from the machine he commanded. They were a little boxier, the armor not well sloped to deflect a shell. But they hit hard; they carried two-inch guns, not inch-and-a-halfers. All things considered, U.S. and C.S. machines were about even when they met on equal terms.

Morrell didn't intend to meet the Confederates on equal terms. Hitting them from ambush was a lot more economical. "Range to the lead barrel?" he asked Sergeant Pound.

He wasn't surprised to hear Pound answer, "It's 320 yards, sir," without the slightest hesitation. The gunner had been traversing the turret to keep that barrel in the gunsight. He wasn't just ready. He was eager. That eagerness was part of what made him such a good gunner. He thought along with his commander. Sometimes he thought ahead of him.

"Let him have it," Morrell said.

"Armor-piercing, Sweeney!" Pound said, and the loader slammed a black-tipped round into the breech. The gunner traversed the turret a little more, working the handwheel with microscopic care. Then he fired.

The noise was a palpable blow to the ears. It was worst for Morrell, who'd just stuck his head out the cupola so he could see the effect of the shot. Fire spurted from the muzzle of the cannon and, half a second later, from the side of the Confederate barrel. Side armor was always thinner than at the front or on the turret.

"Hit!" Morrell shouted. "That's a goddamn hit!" Easier to think of it as the sort of hit you might make in a shooting gallery, with little yellow ducks and gray-haired mothers-in-law and other targets going by on endless loops of chain. Then you didn't have to contemplate that hard-nosed round slamming through armor, rattling around inside the fighting compartment, and smashing crewmen just like you-except they wore the wrong uniforms and they weren't very lucky.

Smoke started pouring from the wounded barrel, which stopped dead-and dead was the right word. A hatch at the front opened. A soldier in butternut coveralls-probably the driver-started to scramble out. Two machine guns opened up on him from Morrell's barrel. He crumpled, half in and half out of his ruined machine.

As Morrell ducked down inside the turret, it started traversing again. Sergeant Pound had commendable initiative. "Another round of AP, Sweeney!" he bawled. "We'll make meat pies out of 'em!" The loader gave him what he wanted. The gun bellowed again-to Morrell, a little less deafeningly now that he was back inside. The sharp stink of cordite filled the air inside the turret. The shell casing came out of the breech and clanged on the floor of the fighting compartment. It could mash toes if you weren't careful. Peering through the gunsight, Pound yelled, "Hit!" again.

"Was that us, or one of the other barrels here with us?" Morrell asked.

"Sir, that was us." The gunner was magisterially convincing. "Some of those other fellows couldn't hit a dead cow with a fly swatter."

"Er-right." Morrell stuck his head out of the cupola. All three of the lead Confederate barrels were burning now. Somebody in one of the other U.S. machines must have known what to do with his fly swatter.

A rifle shot from a Confederate infantryman cut twigs from the oaks above Morrell's head. He didn't duck. His barrel was well back in the shade. Nobody out there in the open could get a good look and draw a bead on him. That didn't mean a round not so well aimed couldn't find him, but he refused to dwell on such mischances.

He hoped the Confederates would try to charge his barrels. He could stand them off where he was for quite a while, then fall back to another position he'd prepared deeper in the woods. Defense wasn't his first choice, but that didn't mean he couldn't handle it. And the enemy, charging hard, might well be inclined to run right on to a waiting spear.

But the Confederates had something else in mind. After about ten minutes of confusion, they started lobbing artillery shells toward the woods. At first, Morrell was scornful-only a direct hit would make a barrel say uncle, and hits from guns out of visual range of their targets were hard as hell to come by. But then he caught the gurgling howl of the shells as they flew through the air and the white bursts they threw up when they walked toward the barrels.

Swearing, he ducked down into the turret and slammed the cupola hatch behind him. "Button it up!" he snarled. "Gas!" He got on the wireless to all the barrels he commanded, giving them the same message. "Masks!" he added to the men in his own machine. "That's an order, God damn it!"

Only when he put on his own mask did Pound and Sweeney reach for theirs. He couldn't see the driver and the bow gunner up at the front of the hull. He hoped they listened to him. If the barrel stayed buttoned up, the men would start to cook before too long. It might have been tolerable in France or Germany. In Ohio? Right at the start of summertime? In gas masks to boot?

Sergeant Pound asked an eminently reasonable question: "Sir, how the hell are we supposed to fight a war like this?"

"How would you like to fight it without your lungs?" Morrell answered. His own voice sounded even more distant and otherworldly than Pound's had. He couldn't see the gunner's expression. All he could see were Pound's eyes behind two round portholes of glass. The green-gray rubber of the mask hid the rest of the sergeant's features and made him look like something from Mars or Venus.

Looking out through the periscopes mounted in the cupola hatch was at best a poor substitute for sticking your head out and seeing what was going on. Shoving one of those glass portholes up close enough to a periscope to see anything was a trial. What Morrell saw were lots of gas shells bursting.
