A hexagonal columnar crystal undergoes a shear-melting transition above acritical shear rate or stress. We combine the analysis of the shear-thinningregime below the melting with that of synchrotron X-ray scattering data undershear and propose the melting to be due to a proliferation of dislocations,whose density is determined by both techniques to vary as a power law of theshear rate with a 2/3 exponent, as expected for a creep model of crystallinesolids. Moreover, our data suggest the existence under shear of a line hexaticphase, between the columnar crystal and the liquid phase
