How do Daivd and Alan try escape capture? What does this kind of "Flight" do to each of them?

They walked in the dark uphill until they came to a cleft of a great mountain, named Corrynakiegh, where a cave lay in which they could hide. They remained in this spot for nearly five pleasant days. They could sneak to a spot near the river and make a fire to warm themselves and cook the fish they caught in the river. They begin to get on each others nerves. Alan attempted to teach David how to use a sword. He was never pleased with David's progress and David thought at times that he might run the sword through him. But, David was pleased with his ability to stand in against Alan.
