Algebra, VIII, p. 45, § 3. Simple Modules

Let A be a principal ideal domain (VII, §1, No. 1, p. 1, Definition 1) that is not a field. For every irreducible element π\pi of A, the A-module As/(π)A_s/(\pi ) is simple, and every simple A-module is isomorphic to such a module (VII, §4, No. 8, p. 25, Remark 4). For n⩾2n\geqslant 2, the A-module As/(πn)A_s/(\pi^n) is indecomposable (VII, §4, No. 8, p. 24, Proposition 8) but not simple.

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
