"Captain Dingfield sent them men over here to knock down and burn that bridge; and I reckon he's go'n' to do it if he can."

"And I am sent here to prevent him from doing it; and I shall do so if I can. You may speak out loud, Knox, just what you wish to say," said the major rather impatiently.

"If you look at that map you had on the housetop, you will see that the hill road crosses the east road, just as this south one does here. Ain't that so, Artie? You have been over there, they say," said the sergeant, appealing to the major's aid.

"It does; I was up there some time this morning; but I don't know where it leads to," replied Artie.

"It stands to reason that it crosses this railroad somewhere within five miles of this cross-road. That's the way the Texicans are coming down here to destroy the bridge. I've said my say, and I hain't got nothin' more to say," added Knox, wheeling his horse out of the circle that surrounded the commander.

"Artie, do you know where Captain Truman is posted with his command?" asked the major in rather hurried tones.

"I do not," replied the aid, as he had now practically become, though the position was not regular for a private.

The commander pointed out the knoll behind which the captain's force had been sent.

"Follow the east road till you can see behind that hill. Captain Truman is there, and you can readily find him," continued Major Lyon. "Give him my order to move his command out to the east road, and there await further orders."
