13th Cav at Camp Furlong?

[Retired Army Noncom]

Troops F,H,K M and a MG Troop were at Camp Furlong when Poncho attacked at Columbus NM. 13th Cav guarded the border from El Paso to the NM/AZ border. Would anyone know the whereabouts of the other troops along the border by troop when Poncho attacked Columbus?

 

Thanks
