During the American Civil War, the northern uniforms, worn by Union soldiers, were primarily made of wool and featured a dark blue color. The standard uniform consisted of a frock coat, trousers, and a kepi or slouch hat, often adorned with insignia indicating rank. The blue uniforms were designed to provide a sense of unity and distinction from the Confederate forces, who typically wore gray or butternut-colored clothing. The use of blue also symbolized the Union's commitment to preserving the nation.
Soldiers began wearing the kepi, a circular, flat-topped hat with a visor, during the mid-19th century. It became particularly popular during the American Civil War (1861-1865) and was commonly associated with French military uniforms. The kepi has since been adopted by various military forces around the world, especially in France, where it remains a symbol of military tradition.
Some "construction workers (hard hats)" made the news during the war, supporting the fighting men in Vietnam; some muscle was used during this support.
