Since the prefix be- in besmirch means "to make or cause to be," when you besmirch something, you cause it to have a smirch. What's a smirch? A smirch is a stain, and to smirch something is to stain it or make it dirty. By extension, the verb smirch came to mean "to bring discredit or disgrace on." Smirch and besmirch, then, mean essentially the same thing. We have William Shakespeare to thank for the variation in form. His uses of the term in Hamlet ("And now no soil nor cautel doth besmirch the virtue of his will") and Henry V ("Our gayness and our gilt are all besmirch'd with rainy marching in the painful field") are the first known appearances of besmirch in English.
