  We study the physics of quark deconfinement on domain walls in
four-dimensional supersymmetric SU(N) Yang-Mills theory, compactified on a
small circle with supersymmetric boundary conditions. We numerically examine
the properties of BPS domain walls connecting vacua k units apart. We also
determine their electric fluxes and use the results to show that Wilson loops
of any nonzero N-ality exhibit perimeter law on all k-walls. Our results
confirm and extend, to all N and k, the validity of the semiclassical picture
of deconfinement of Anber, Sulejmanpasic and one of us (EP), arXiv:1501.06773,
providing a microscopic explanation of mixed 0-form/1-form anomaly inflow.
