  We argue that the deconfinement transition of large-N Yang-Mills theory is
the condensation of very long and self-intersecting chromo-electric flux
strings (QCD string), which is analogous to the formation of a black hole in
string theory. We do this by using lattice gauge theory and matrix models. As
evidence, we derive an analytic formula for the deconfinement temperature in
the strong coupling limit and confirm it numerically. Dual gravity descriptions
interpreted in this manner should make it possible to understand the details of
the formation of black holes in terms of fundamental strings. We argue that
very simple matrix models capture the essence of the formation of black holes.
