Is there some point in the story when all seem hopeless, when it looks like the hero is going to die then suddenly he is rescued unexpectedly?

When Santiago sees omens that portend the invasion of an army, he tells the chiefs and, after some deliberation, they decide to ready themselves for war - even though this is against the tradition of the oasis, which is usually considered neutral ground. The chiefs make a stipulation: if the enemy arrives, the chief will give Santiago a piece of gold for every 10 enemies slain; if Santiago's vision is wrong, he will be killed. Walking home from his meeting with the chiefs Santiago is pensive but sure that he has made the right decision. Suddenly, he is assailed by a man with a falcon on his shoulder, dressed all in black, riding a white horse. The man holds a sword to Santiago's head and demands to know how he knew of the coming of the army. Santiago, frightened, explains to the man about the omens of the desert and his Personal Legend, concluding that he had no choice. The man understands completely, to Santiago's surprise, and takes his leave, telling Santiago to come see him if he survives the coming days. As the horseman rides away, Santiago realizes that he has just met the alchemist.
