Soldiers, before they left to fight in WW2, were given a Gideons New Testament with Psalms especially printed for them. The Bible contained the following inscription from President Roosevelt,
January 25, 1941, To the Members of the Army:
As Commander-in-Chief I take pleasure in commending the reading of the Bible to all who serve in the armed forces of the United States. Throughout the centuries men of many faiths and diverse origins have found in the Sacred Book words of wisdom, counsel and inspiration. It is a foundation of strength and now, as always, an aid in attaining the highest aspirations of the human soul.
Very sincerely yours,
Franklin D. Roosevelt
