Scarlet and yellow are the colors used for Artillery. The voided cross of St. George refers to the English colonization and development of Virginia, and to perpetuate Grimes Battery, formed at Portsmouth in 1809 and now an element of the organization; it also refers to the War of 1812. The saltire is for Confederate service in the War Between the States. The two fleurs-de-lis are for service in France and Central Europe, World War II; and also allude to the award of the French Croix de Guerre with palm (World War II) for participation in the invasion of Normandy.
