The lines convey the speaker's militants determination. By analyzing some words and phrases such as "not winced nor cried", "bludgeonings" and "not unbowed", the reader can infer that the writer has had a hard life and has been tried to be brought down to his knees, but he is willing to continue and push though the problems he encounters in life.
