The asymptotic solution of the Korteweg‐de Vries equation u τ + ⅓ u xxx + 2 uu x = 0 for initial conditions from which no solitons evolve is obtained as a slowly varying similarity solution of the form τ −2/3 ( V z − V 2 , where V = V ( z/τ ) and z = τ −1/3 x . The results are consistent with, but go somewhat beyond, those recently obtained by Ablowitz and Segur [2] through a rather different approach.
