The nonlinear evolution of the shock wave from an expanding supernova is studied, going beyond the perturbation analysis of Baierlein, Schwing and Herbst (1981). The major findings are the following: (1) the magnetic field changes little in configuration and strength; (2) the magnetic forces will compress the gas by the factor 2 pi times the ratio (Alfven speed)/(sound speed), a factor that can easily lie in the range 100-1000; (3) as the gas moves toward the valley, its motion becomes supersonic but not super-Alfvenic; and (4) a polarization map of the Canis Major R1 region should find a magnetic field directed from one stellar cluster to the next, parallel to the shock. In comparison with the earlier Parker instability model, the magnetic pressure dominates thoroughly over the gas pressure, but the latter's influence may not be ignored.
