We prove in this paper the stability and asymptotic stability in H1 of a decoupled sum of N solitons for the subcritical generalized KdV equations ut + (uxx + up)x = 0 (1 < p < 5). The proof of the stability result is based on energy arguments and monotonicity of the local L2 norm. Note that the result is new even for p = 2 (the KdV equation). The asymptotic stability result then follows directly from a rigidity theorem in [16].
