The authors consider the heterotic string in arbitrary background gauge fields. The full gauge Chern-Simmons terms are shown to be reproduced in the divergent terms of the corresponding sigma model to the two-loop order. The role of the Chern-Simmons terms is discussed from the viewpoint of the local gauge invariance.
