Overview of Civil War insignia
Civil War insignia were the badges a soldier wore to show rank, branch of service, and sometimes unit. Union officers wore rank on their shoulder straps, and Union enlisted men wore it on their sleeves. Branch was shown on caps and by colored trim. Confederate insignia followed a similar idea, but it was far less standardized, and many pieces were improvised.
Insignia can show what a uniform was meant to indicate. They cannot, on their own, prove that a piece is original. Badges were moved between garments, replaced, and copied for reproductions, so treat each device as one clue among several.
Union officer rank insignia
Union officers’ ranks were shown on shoulder straps. The table below lists the standard Union devices from company grade up to general.
| Rank | Shoulder-strap device |
|---|---|
| Second lieutenant | Plain strap, no device |
| First lieutenant | One bar |
| Captain | Two bars |
| Major | Oak leaf (gold) |
| Lieutenant colonel | Oak leaf (silver) |
| Colonel | Eagle (silver) |
| Brigadier general | One star |
| Major general | Two stars |
| Lieutenant general | Three stars |
Metal color was not always consistent across makers and periods, so the device shape is the more reliable first check. Compare color against a period reference before drawing conclusions from it.
What Union enlisted men wore
Enlisted men wore rank on the upper sleeve as chevrons. A corporal wore two chevrons, and a sergeant wore three. Some senior noncommissioned ranks, such as first sergeant, had an additional device above their chevrons. Chevron material and color varied, so check how each one is attached and whether it fits the rest of the garment. For how the chevron system developed later, see US Army chevrons and enlisted rank insignia.
Branch insignia and branch colors
Union branch of service was shown in two main ways:
- Cap insignia on the front of kepis and forage caps. Infantry used a bugle, cavalry used crossed sabers, and artillery used crossed cannons.
- Branch colors on trim, piping, and shoulder straps. Infantry used light blue, artillery red, and cavalry yellow.
These branch colors carried into the later Spanish-American War uniforms, which is covered in Spanish-American War US Army uniforms.
Corps badges
Corps badges were cloth shapes, such as circles, trefoils, and crosses, worn on caps and coats to show a soldier’s corps and division. The Army of the Potomac is usually credited with introducing them in 1863. The shape showed the corps, and the color showed the division. Red was used for the 1st division, white for the 2nd, and blue for the 3rd.
Because corps badges were sewn on, they moved easily between garments. A badge on a coat does not guarantee that the coat belonged to that corps. The idea of marking a formation with a cloth sign came back in the 20th century as shoulder sleeve insignia.
Confederate ranks and insignia, in order
Confederate insignia was less standardized than the Union system. What was worn often depended on the unit, the year, and what was available.
From lowest to highest, the officer ladder ran: second lieutenant, first lieutenant, captain, major, lieutenant colonel, colonel, brigadier general, major general, lieutenant general, and general. Enlisted ranks ran from private through corporal and sergeant, with senior ranks such as first sergeant and sergeant major above sergeant.
In broad terms, the insignia looked like this:
- Company officers (lieutenants and captains) showed rank with bars, braid, or other devices on the sleeve or collar, depending on the period and source.
- Field officers (majors, lieutenant colonels, and colonels) wore stars on the collar instead of the Union oak leaves and eagle.
- General officers wore stars on the collar. Some descriptions also mention a wreath and sleeve lace. The exact pattern varied, so check any general’s insignia against a period reference.
- Enlisted men wore chevrons on the sleeve, similar to the Union system.
Many Confederate devices were homemade or did not follow regulation. A device that looks unusual is not automatically wrong, but it should be compared with documented photographs.
Checking insignia on a uniform
Use these checks together rather than relying on one feature.
- Placement: Does the device sit where period regulations or photographs show it? Union shoulder straps and Confederate collar devices are in different places.
- Attachment: Original insignia is usually sewn or pinned through the cloth. Glue, modern thread, or stitching that does not match the garment’s construction is a warning sign.
- Wear: Insignia should show wear that matches the rest of the coat. A device that is much brighter or cleaner than its garment deserves a closer look.
- Metal: Check weight, casting, and finish. Modern castings can have a uniform surface and crisp detail that look newer than the piece they sit on.
- Match: If you have documented service for the wearer, compare the rank and branch with it. A mismatch can mean the device was moved or added later.
Common mistakes
- Treating a shoulder strap as proof of the rank the coat was made for. Straps were swapped and moved.
- Applying Union rules to Confederate insignia, or the reverse.
- Assuming a homemade or unusual device is wrong. Many units made their own.
- Reading metal color as a precise date marker. Color varied across makers and periods.
