In 1922, when M.K.Gandhi took back non cooperation movement it resulted in rise of many dissent youth voice like B.C.Vohra, Sukhdev, Chandrasekhar Azad & Bhagat Singh. From here Mr. Gandhi's non- violence got competed against revolutionary activities of HRA & later HSRA.
Till hanging of Bhagat Singh, Sukhdev & Rajguru, M.K.Gandhi did not confront Bhagat Singh in any manner. Neither face-off nor any polemic criticism but Sukhdev took an opportunity to critisize Gandhi & wrote a letter to him. In return to this Mr. Gandhi wrote a letter to Sukhdev which he published in his paper Harijan.
Here are two images of letters. First is of Gandhi's reply to Sukhdev & Second is Bhagat Singh's letter to his father.
