  Despite a resurgence of effort over the last decade in the area of massive
stars there is still ambiguity over their evolutionary path, contamination of
their surface abundances and the behaviour of their stellar winds. Here 10 SMC
B-type supergiants are analysed applying a unified model atmosphere code
FASTWIND to intermediate resolution spectra from the ESO Multi Mode Instrument
(EMMI) on the NTT telescope. Combined with the 8 targets analysed in paper 1,
this work provides observational results on the properties of the winds and
chemical compositions of B-type supergiants in the SMC. This paper emphasizes
and substantiates the implications for stellar evolution from paper 1; that
current theoretical models need to produce larger degrees of surface nitrogen
enhancements at lower rotational velocities. In addition a significant
discrepancy between theoretical and observed mass-loss rates is discussed which
will have important implications for the rotational velocities obtained from
stellar evolution calculations. Furthermore, an initial calibration of the
wind-momentum luminosity relationship for B-type supergiants in a low
metallicity environment (Z = 0.004) is presented.
