Optical Range of Civil War binoculars or telescopes

Hello,

I have a graduate student who is interested in creating a view shed for two forts in Colorado in the 1850s. He is curious to know the optical range of a mid-nineteenth century pair of binoculars (field glasses) or telescope so that he can learn how far a soldier in a fort could see compared to a Native American without such technology. Any estimates or sources where such information might exist would be most appreciated.
