  The structure of the Small Magellanic Cloud (SMC) outside of its main body is
characterised by tidal branches resulting from its interactions mainly with the
Large Magellanic Cloud (LMC). Characterising the stellar populations in these
tidal components helps to understand the dynamical history of this galaxy and
of the Magellanic system in general. We provide full phase-space vector
information for Southern Bridge clusters. We performed a photometric and
spectroscopic analysis of twelve SMC clusters, doubling the number of SMC
clusters with full phase-space vector information known to date. We reclassify
the sample considering 3D distances and 3D velocities. We found that some of
the clusters classified as Southern Bridge objects according to the projected
2D classification actually belong to the Main Body and Counter-Bridge in the
background. The comparison of the kinematics of the genuine foreground Bridge
clusters with those previously analysed in the same way reveals that Southern
Bridge clusters are moving towards the LMC and share the kinematics of the
Northern Bridge. Adding to our sample clusters from the literature with CaT
metallicity determinations we compare the age-metallicity relation of the
Southern Bridge with the one of the Northern Bridge. We reinforce the idea that
both regions do not seem to have experienced the same chemical enrichment
history and that there is a clear absence of clusters in the Northern Bridge
older than 3Gyr and more metal-poor than -1.1, which would not seem to be due
to a selection effect.
