Lawrence found the prisoner they had taken shaking with terror, for some of the men had coolly informed him that after dinner he was to be hanged. Lawrence was about to reprimand the men for their cruel joke, when it occurred to him he might use the fellow's fears to some advantage. So he told him if he would tell all he knew, not only would his life be spared, but that he would be paroled, but he would have to be careful and tell nothing but the truth. The prisoner eagerly embraced the opportunity, and confirmed what Harry had said. He moreover stated that before Porter and Poindexter parted they had agreed to gather up all the men they could, and join forces again somewhere along the line of the Hannibal and St. Joseph Railroad. "I guess that is straight enough for Guitar to believe, instead of that upstart lieutenant," said Harry. Back to find Guitar the scouts rode; but it was night when they found him and then nearly where they had left him. All day his men had marched beneath a broiling sun, and when they found out how they had been led astray, against the protests of Harry, they wanted to lynch the smart lieutenant; and it was a long time before the poor fellow heard the last of it. Colonel Guitar concluded to rest his men until morning, and then continue the pursuit. "I will chase Porter clear to the Iowa line, if necessary, to catch him," he said. While it was arranged that Colonel Guitar should march straight for Mexico, Lawrence, with a detail of ten men dressed as guerrillas, was to follow directly on the trail of Porter, thus keeping track of his movements. Lawrence chose ten of the Merrill Horse to go with him. One of the men in looking over the squad and noticing that with Lawrence, Dan, and Harry there were thirteen of them, demurred, saying that another man should be added, as thirteen was an unlucky number. "No thirteen for me," he said. "Step aside," ordered Lawrence. "I want no thirteen cranks. I, for one, am not troubled over the old superstition of thirteen. Who will volunteer to take this fellow's place?" A dozen were eager to go, and Lawrence chose a manly looking fellow. "Our timid friend here counted wrong," he said. "He forgot Bruno, and he is equal to a dozen men." This raised a laugh, and the party started in the highest spirits. After going a short distance, Lawrence halted and made his men a short speech. "Boys," he said, "dressed as we are, it will be certain death if we are captured. If circumstances arise where we must fight, fight to the death--never surrender. We are strong enough to beat off any small party, and large ones we must avoid. But remember, our object is to get information, not to fight. To all appearances we must be simon-pure guerrillas. If we meet with guerrillas, as no doubt we will, keep cool, and let Harry or me do the talking."
