Swords and Saddles by Jack Campbell

in the past. Aged ruins of abandoned buildings, some still bearing the scorches of fire on their walls, were spotted near once-cultivated fields gone wild. Even stranger, another desolate tower lay tumbled to one side of the large road not far from where the cavalry column crossed it. Lieutenant Garret was sent to investigate and came back bewildered. “It’s not the same architecture as the fortress ruins, sir. The tower seems sort of Roman, like the ones on Hadrian’s Wall.”
    First the Hanging Gardens of Babylon and now Hadrian’s Wall. “Kansas seems to be gaining ancient historical artifacts at a very unusual rate, lieutenant. How old is that tower, do you think?”
    “It seems a lot younger than the city, sir. I’d guess it’s maybe a hundred years old, or maybe two hundred. That’s just a guess.” Garret had been growing more and more puzzled. “Captain, are these ruins being kept secret for some reason? I’ve never heard a word about them.”
    “That’s because they haven’t been here, lieutenant.” Feeling increasingly unsettled, Benton turned to face the column. “Mount up!” With he and his men settled into their saddles, he ordered the company into motion again, eager to see Fort Harker and the adjacent town of Ellsworth as soon as possible.
    It was well after noon when they came over the last of the rises before the river lowland holding Fort Harker and Ellsworth. They had come up from the south, so both the fort and the town should have been almost due north of them. The Smoky Hill River which skirted both places was there, but otherwise the landscape was marked only by another wide road leading east. There was no sign Fort Harker or Ellsworth had ever been here, no indication the railroad line coming in from the east and then up along the Smoky Hill had ever been built here. How could an entire town and a fort with more than seventy buildings have vanished within a couple of weeks? How could the rail line and the warehouses beside it which had been there for a few years also have disappeared without a trace?
    Sergeant Tyndall made a strangled sound as he looked east. Within a few miles the road entered a broad cultivated and cleared area, running through it, and up to the sealed gates of a city walled in stone which had been built between Spring Creek and Clear Creek. The city was miles east of where Ellsworth or Fort Harker should be, much bigger than either Ellsworth or the fortress to the south that they’d seen in ruins, and it was undisputedly still occupied. “Cap’n, begging your pardon, sir, but what the hell? Where’s the fort and where’s the town and what’s that?”
    “It’s not Ellsworth.” Benton leveled his field glasses, making out banners on the top of high walls and some sort of castle or citadel in the center of the city. “There’s fighting going on. People on the walls are defending the city against a force encamped before it. See the ladders the attackers are putting up against the walls?”
    Lieutenant Garret nodded, peering through his own field glasses. “Sir, I don’t hear any gunshots.”
    Neither did he, Benton realized. Nor could he see the impossible to miss clouds of gun smoke which should have veiled the battlefield.
    “What do we do, sir?” Tyndall asked.
    His instructions from the colonel hadn’t covered this particular set of circumstances, but they had left him the authority to use his discretion if he encountered something not mentioned in those instructions. “There’s a city under attack. That’s clear enough. We’re to defend Ellsworth and other towns or settlers if they come under attack. That’s not Ellsworth, but it’s a city. We’ll ride that way, evaluate the situation as we get closer, and take appropriate action.”
    Tyndall nodded, clearly relieved now that an officer had laid out a familiar and rational course of action.
    Benton rode up close to Garret and spoke softly. “The men know something is wrong, lieutenant. They
