  We present branching fraction measurements of charged and neutral B decays to
Dpi-, D*pi- and D**pi- with a missing mass method, based on a sample of 231
million Y(4S)-->BBar pairs collected by the BaBar detector at the PEP-II e+e-
collider. One of the B mesons is fully reconstructed and the other one decays
to a reconstructed charged pion and a companion charmed meson identified by its
recoil mass, inferred by kinematics. Here D** refers to the sum of all the
non-strange charm meson states with masses in the range 2.2-2.8 Gev/c2.
