Tensions between the "roughs" of Carlisle and the soldiers of the neighboring Carlisle Barracks had previously been confined to the bars and dance halls along the notorious East Louther Street but broke out in a serious armed conflict on Election Day in the center of the Pennsylvania town. A large group of armed soldiers appeared in the town square and when they were resisted exchanged extended gunfire with armed civilians before retreating back towards their quarters. Two people were killed and around a dozen wounded. No charges were ever brought on either side but the local commander, Brevet Brigadier-General William N. Grier, restricted his troops to the Barracks from then on. (By John Osborne)
