I was recently in Atlanta History Center achives and saw a knapsack that was originally issued to one of these units:
It was a cow hide pack with the fer still intact. The packs were reissued to the 8th USCT. On the inside flap is written Ezra Brooks 8th Inf. USCT.
I was wondering if there are any early war photos of the Chasseur Units with these packs. I know they took photos in the uniforms before getting rid of them but i have not seen any photos of the knapsacks. Or even better but unlikely any pictures of the 8th USCT with these packs.
