True that Wainwright might not really had a choice, but he performed his duties as a soldier valiantly and professionally. "I'll be Bataan if I'm alive", he told MacArthur as he said goodbye, and fought until his men were essentially out of food and ammunition. Yes, it might had been dictated by the circumstances, but if what he did was not considered bravery and professionalism, I don't know what is!
Perhaps I'm a bit biased due to my liking for MacArthur, who's a controversial figure to begin with. Nevertheless, Wainwright is just a big a hero in my eyes
