NOT sure .. the reason I posted this was I saw a clip yesterday on GUNS AND AMMO tv about this.. They were at the Cody WY museum for firearms..also stated this was the first.. Talked about how T Roosevelt pulled some strings to get this into use for the war he was headed into.. also were some issues during the skirmish..and heavy casualties.. But also the first time we found a war headed uphill into a heavily armed force...
