“Sir, you’re right. And no, I don’t think this set of matchsticks would hold a Hunley … not all in one piece. I think they’ve disassembled it. They’re moving it in parts. They’re sneaking it off, bit by bit, onto barges. Dozens of flat-bottoms go by every day. We could never search every craft that comes through the delta. It just isn’t possible; we don’t have the people. And these bayou boys, they’ve got friends in Barataria. They could buy help, if they needed it.”

From her spot behind the crates, Josephine considered their incorrect theory.

It wasn’t a half-bad idea, and just this once she was glad that her brother’s crew had been so slow moving the craft. If it’d gone any quicker, they might’ve disassembled it — and then what? Then the Texians would be on to them. Still, it was cold comfort.

The Union had said outright that they wouldn’t spare extra money on a recovery mission until it could be demonstrated that the Ganymede actually worked. And worked without killing anyone inside it.

To date, such a demonstration had not been achievable, not on any serious scale. The controls were a mystery to every sailor the guerrillas had brought aboard, and the bayou engineers had only just discovered how to rig up makeshift ventilation pumps. No one had died on board since the ventilation had been installed, so progress was being made. It just wasn’t progress enough.

Not yet.

Deep down, Josephine knew it was possible to move the Ganymede, and move it safely. She believed it with all her heart — she’d seen the elegant schematics left over from the Confederate Hunley’s last, best efforts before he’d drowned in an earlier prototype. She’d held the secret rolled-up blueprints in her hands and read all about the machine’s destructive capacity, as laid out by its now-dead creator.

And she was confident to the point of obsession that if the Ganymede could be given to the Federal government, and reproduced, and brought into the war … then even Texas would back away, and at last the Rebs could be choked into surrender.

Much earlier in the war, the Anaconda Plan — an attempt to blockade the supplies to the whole southeast — had failed. But then, it’d been tried only with ordinary warships. Imagine how much more effective it could have been — and might be again! — if the blockade were undertaken with craft that swam below the water’s surface. Just consider the possibilities of such extraordinary machines, hidden and powerful, able to destroy ships from the Gulf or the Atlantic without having ever been seen.

It could end the war. Maybe the simple threat of it could do so. How much more could the Rebels really stand, anyway? Any idiot could see they were living on the cusp of what was sustainable; any fool could pick up a newspaper and understand in seconds that this couldn’t go on much longer.

Of course, everyone had been saying so for years.

“Tell me, then. What does this mean? How do we respond, in case you’re right?”

“First, I think we should clear out the bayous. Make a huge push — just wipe those bastards out of the wetlands for good. We’ll round up a few, twist some thumbs, and find out what they’ve done with the ship. Maybe if we’re lucky, they haven’t finished moving it off yet.”

After a pause, the colonel asked, “The damn thing failed, and failed again. Do you think the Union really wants it?”

“Mr. Hunley was a genius, sir, and so were the fellows who took up his work after he died. If the blues think they can start up that machine, they’ll pay for it, and pay top dollar. If they aren’t funding the operation already.”

“We may as well assume they are. Those swamp rats, they don’t have the money or resources to make such a stink on their own. Out there in the sopping wet middle of noplace, there’s not even anything worth stealing. Someone’s keeping them in guns and ammo.”

“Sir, I—”

“Wait. Hush.”

“Sir, what—?”

“Hush, I said.” He dropped his voice so low that Josephine could scarcely make out the words. “Do you hear that?”

The lieutenant whispered back. “Hear what, sir?… Oh. I think…”

“What is it?”

“Sir, I’m sure it’s nothing.”

Josephine Early wasn’t sure. She heard it, too, very faintly — it was coming from the far side of the men, from below the wharf, nearer the water. Crouching down, she reached for the Schofield under her skirt and retrieved it from the heavy-duty garter where it had been fastened. She removed her gloves and stuffed them into her pocket, then grasped the gun carefully, readying it, adjusting her grip.

“It sounds like … like someone having a hard time breathing.”

“Yes, sir, something like that. Where’s it coming from?”

“There … no. Over there. Or maybe over there.” He indicated several directions, none of them certain.

The woman behind the crates closed her eyes, in case it’d help her listen harder. She concentrated and breathed as shallowly as she could — until the pounding of her heart was nearly as loud as the distant wheezing. Her hips and lower belly ached against her foundation undergarments from maintaining such a cramped posture, and her head was beginning to throb.

“Cardiff, I don’t like this.”

“Me either, sir. Maybe we should be on our way.”

The colonel wasn’t quick to move, but he was quick to reach into the gun holster he wore hanging off his shoulders. Josephine couldn’t see what he carried, probably a Colt service revolver — something loud and high caliber, being a Texian and a man of authority. Very likely, it was the kind of gun that could take somebody’s head off in a pinch.

Against all reason, she was glad to see he had it. He was going to need it, but not to defend himself against any hidden Union spies like herself, crouching behind crates. She was sickeningly confident of that much. She knew it from the rushing sound of broken breaths being dragged in and out through rotted throats. She knew because the sound was coming from everywhere and nowhere at once, drawing closer, coming toward the lantern light on the dead-end wharf.

The lieutenant drew a handgun as well, more nervously than the colonel. He instinctively retreated until his back was nearly pressed against the commanding officer’s — and he held the lantern high, throwing the light as far as he could, hoping to get a glimpse of whatever was approaching from the darkness.

Josephine didn’t want to see it, but she needed to.

This had all been a terrible idea — on everyone’s part, and at least the colonel ought to have known better. Maybe he had known better, but he was cocky with his guns and his rank; maybe the lieutenant had been the ignorant one, seeing the place during the day when the sun had chased off the worst of the shadows.

If only they’d left the light off. If only they’d kept their voices down.

Every muscle in Josephine’s body was tighter than a violin string. She watched around the corner, crouched on one knee, gun held up at the ready, almost next to her face as if she were praying. She considered running, back out the way they’d come — but no, they’d see her, or hear her. They’d open fire, not knowing she wasn’t the most dangerous thing on the wharf, and not knowing she only meant to escape.

Besides.

She jerked her head away from the corner and listened.

Coming down the walkway, up from the river in staggering, shambling steps that didn’t keep time like an ordinary walker.…

Josephine retreated away from the crate’s edge, shrinking herself to the fullest extent possible, down at the bottom edge where the angle was sharpest and the shadow was deepest.

It wouldn’t help. They didn’t have to see her to know she was there.

The ragged, sickly gasps grew nearer. Josephine tried to sort them out — to determine how many were coming. She detected three on the far side of the Texians, who were sweating with fear; she was sure of two more, from farther back on the wharf; and one more … no, two more coming up the back way, cutting off the only obvious means of retreat.
