Yes and No. It was partly a sign of the times. When you march to war with another man, you become brothers. For many people, it's hard to hold onto those old predjudices when you've lived through mortal combat with someone. There are tons of examples of this during World War I and II. When you're hunkered down in a foxhole with man, getting ready to run out and attack, little things like religion seem to mean a lot less.
