During America’s Civil War, flags were enormously important to soldiers. They were so important that soldiers would sacrifice their lives to protect their flags from enemy capture. State and regional regimental flags were morale builders, and they were a great source of pride for the soldiers. They also had a more practical purpose. Battlefields could get loud and confusing, and it could be easy for regiments to become scattered. So, a regimental flag would mark the position of the regiment and be a visual rallying point for the soldiers to follow.[1]
But America isn’t the only nation who has treasured her flag in battle. Even nations in ancient history would fly their flag or banner at their front lines. Seeing their flag at the front lines would give soldiers a feeling of hope, and it was a focal point for them during their battles.[2]
Shortly after their exodus from Egypt, ancient Israel fought against the Amalekites. During this battle, Moses went up on a hill with his staff. When he held up his hand and staff, Israel prevailed. But if he lowered his hand and staff, the Amalekites prevailed. Two men, Aaron and Hur, went up with Moses to help him hold his hands up during the entire battle. Israel ultimately won the battle and defeated the Amalekites.
