what is the main conclusion don quixote draws after retreating from his attack on the giants? that success is not measured by mere wealth but by challenging one's destiny that he can blame a magician for altering his chances for defeating the giants in a skirmish that his situation will improve if he remounts his horse and overcomes his shame that all are subjected to the whims of change but especially those involved in battles

In Chapter 8 of Miguel de Cervantes' Don Quixote, Sancho Panza and Don Quixote come across a field of windmills. Don Quixote is convinced that the windmills are giants although Sancho tells him otherwise. He then goes off to fight the so-called 'giants' and inevitably gets beaten. The main conclusion Don Quixote draws after retreating from his attack on the 'giants' is that that he can blame a magician for altering his chances for defeating the giants in a skirmish. In the end, he still thought that a magician was playing tricks on him - turning the giants into windmills in order for him to lose.
