They pounded past a farmhouse the Kiowas had burned in a raid a couple of years earlier. Custer recognized those ruins; they meant he was less than a mile from the border with the Indian Territory. Up ahead, the Kiowas squeezed still more from their ponies. Custer smiled savagely. That might get them over the line, but even those tough animals would start wearing down soon. "And then," he told the wind blowing tears from his eyes, "then they're mine, sure as McClellan belonged to Lee twenty years ago."

He fired again at the Kiowas, and shouted in exultation as one of them slid from his horse's back and thudded to the ground, where, after rolling a couple of times, he lay still. "Good shot," his brother said. "Hell of a good shot."

"We've got 'em now," Custer said. The first Kiowas had to be over the line. He didn't care. "We won't let 'em get away. Every last redskin in that band is ours." How his men cheered!

And then all of Custer's ferocious joy turned to ashes. Tom pointed off to the east, from which direction a squadron of cavalry was approaching at a fast trot. All the Kiowas were over the line by then. They reined in, whooping in their incomprehensible language. They knew they were safe.

Custer knew it, too. Chasing the Kiowas into Indian Territory, punishing them, and then riding back into Kansas with no one but the Indians the wiser, was one thing. Doing it under the watchful eyes of that other cavalry squadron was something else again. Hating those horsemen, hating himself, Custer held his hand high to halt his men. They stopped on the Kansas side of the line.

The approaching cavalrymen wore hats and blouses of a cut not much different from those of Custer's troopers. Theirs, though, were gray, not the various shades of blue the U.S. cavalry used. And a couple of their officers, Custer saw, were in the new dirt-brown uniforms the Confederate States had adopted from the British. The limeys called that color khaki; to the Rebs, it was butternut.
