In June 1918 his regiment arrived in France, where it held the St. Die sector of the Lorraine front, August–September. Regiment was kept in reserve during opening of the Meuse-Argonne offensive before being sent to Marbache Sector along the Moselle in October. Served in battalion aid station at Pont-à-Mousson under heavy artillery fire, November 5–10, before being sent to Lesménils, where he was gassed on the night before the Armistice. Threatened with court-martial in January 1919 for violating order forbidding black soldiers from speaking with French women, but charges were dropped, and Isum was honorably discharged in March 1919. Returned to Los Angeles and job at the Times. Married Zellee Jones. Retired from work in 1930s as heart condition linked to wartime gassing worsened.

(Rachel Isum and Jackie Robinson married in 1946, the year before he joined the Brooklyn Dodgers.)
