The critical line for the commensurate· incommensurate transition in the two dimensional classical sine-Gordon system is determined with the use of the Bethe ansatz equations for the massive Thirring model with finite hole density. Except slight differences the behavior of the critical line is the same as that obtained on the basis of the self-consistent harmonic phonon approximation.
