When the Union troops in the field began to run a way what happened to the flag?

When Union troops began to retreat in the field, their flags, which symbolized their unit and national pride, often fell into disarray or were abandoned. In some cases, the flags were heroically defended by soldiers who risked their lives to prevent the enemy from capturing them, as losing the flag was considered a significant disgrace. The fate of the flag depended on the circumstances of the retreat and the determination of the troops to protect their colors.
