When Sam organized his expedition at Camp Jackson, Jake had two motives in joining it. In the first place things around the camp looked too much like genuine preparation for a hard fight with the enemy, and Jake thought that if he should enlist he would be forced to fight, which was precisely what he did not mean to do if he could help it. By joining Sam's party, however, he would escape the necessity of enlisting, and he thought that the little band was going away from danger instead of going into it. He thought, too, that if any real danger should come, under Sam's leadership, he could run away from it, or sneak out in some way, and as he would not be a regularly enlisted soldier, no punishment could follow. This was his first reason for joining. His second one was still more unworthy. He was bent upon doing Sam all the secret injury he could, and he thought that by going with him he would have opportunities to wreak his vengeance, which he would otherwise lose. When he learned, as we have seen, whither Sam was leading his party, and on what errand, he was really frightened, and Sam's sharp rebuke made him still bitterer in his feelings toward his young commander. A coward with a grudge which he is afraid to avenge openly, is a very dangerous foe. He will do anything against his adversary which he thinks he can do safely, by sneaking, and when Jake Elliott threw himself down on his pile of moss he did not mean to go to sleep. He meant to revenge himself on Sam before morning, and at the same time to make it impossible for the expedition to go on. If he could force Sam to return to Camp Jackson, he said to himself, he would humiliate that young man beyond endurance, and at the same time get himself out of the danger into which Sam was leading him. Everybody would laugh at Sam, and call him a coward, and suspect him of failing in his expedition purposely, all of which would please Jake Elliott mightily. How to accomplish all this was a problem which Jake thought he had solved by a sudden inspiration. He had formed his plan at the very moment of receiving Sam's rebuke, and he waited now only for a chance to execute it.
