Adopted in 1861, the enlisted frock coat is single breasted and made of Dark Green wool with 1/8”piping of light or emerald green on cuffs and collar.  The skirt is made long because they were issued un-hemmed and each soldier hemmed the coat to regulation; (mid way between the top of the hip and the bend of the knee).  The coat has a nine ¾” button front and a functional sleeve cuff  with two 5/8” button closure.  There are two 3/4” buttons at the waist on the back at the top of the pleats.  Buttons are Goodyear rubberized general service Eagle buttons. By July of 1863, some soldiers may have worn the blue sack coats as it was sometimes difficult to replace the green frocks. There are stories of some soldiers dying the blue coats green to darken them further. The idea of the green uniform was to help camouflage them so they could blend into their surroundings. 

A mix of dark green or sky blue trousers were worn depending upon replacements available. 

Although many of the soldiers had changed to a more traditional uniform, they would maintain their green wool forage cap. 

Another unique part of their uniform was the knee high leather gaiters/leggings worn to keep their trousers from getting caught on briars and underbrush.
