In his last fight, Ross defended his title on May 31, 1938, against fellow three-division world champion Henry Armstrong, who beat him by a decision in 15. Although Armstrong pounded Ross inexorably and his trainers begged him to let them stop the fight, Ross refused to stop or go down. Barney Ross had never been knocked out in his career and was determined to leave the ring on his feet. Some boxing experts view Ross's performance against Armstrong as one of the most courageous in history. Some believe that Ross's will to survive every tough fight on his feet had to do with his understanding of his symbolic importance to Jews. That is, Jews would not only fight back, but they would not go down.
