  The generalized massive Thirring model (GMT) with $N_{f}$[=number of positive
roots of $su(n)$] fermion species is bosonized in the context of the functional
integral and operator formulations and shown to be equivalent to a generalized
sine-Gordon model (GSG) with $N_{f}$ interacting soliton species. The
generalized Mandelstam-Halpern soliton operators are constructed and the
fermion-boson mapping is established through a set of generalized bosonization
rules in a quotient positive definite Hilbert space of states. Each fermion
species is mapped to its corresponding soliton in the spirit of
particle/soliton duality of Abelian bosonization. In the semi-classical limit
one recovers the so-called SU(n) affine Toda model coupled to matter fields
(ATM) from which the classical GSG and GMT models were recently derived in the
literature. The intermediate ATM like effective action possesses some spinors
resembling the higher grading fields of the ATM theory which have non-zero
chirality. These fields are shown to disappear from the physical spectrum, thus
providing a bag model like confinement mechanism and leading to the appearance
of the massive fermions (solitons). The $su(3)$ and $su(4)$ cases are discussed
in detail.
