We present a measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase gamma with a Dalitz analysis of neutral D-meson decays to the K0s pi- pi+ final state from B+/- -> D(*)K+/- decays, using a sample of 347 million BB events collected by the BaBar detector. We measure gamma = (92 +/- 41 +/- 11 +/- 12)deg, where the first error is statistical, the second is the experimental systematic uncertainty and the third reflects the Dalitz model uncertainty. For the ratios rB(*) between the magnitudes of amplitudes A(B- -> D(*)0K-) and A(B- ->D(*)0 K-) we obtain the one-standard deviation intervals [0,0.14] and [0.02,0.20], respectively. All results presented here are preliminary.
