  We find an exact, N=1 supersymmetric kink solution of 5d gauged supergravity.
We associate this solution with the RG flow from N=4 super Yang-Mills theory,
deformed by a relevant operator, to pure N=1 super Yang-Mills in the IR. We
test this identification by computing various QFT quantities using the
supergravity dual: the tension of electric and magnetic strings and the gaugino
condensate. As demanded by our identification, our kink solution is a true
deformation of N=4, that exhibits confinement of quarks, magnetic screening,
and spontaneous chiral symmetry breaking.
