Photo of People Posing on and Around an Observation Tower in the Abandoned Ruins of Fort Holmes on Mackinac Island, Michigan (1870's)

Photo of people, possibly tourists, posing on and around an observation tower in the abandoned ruins of Fort Holmes on Mackinac Island, Michigan, c. 1870s. The fort was occupied by British soldiers and presumably their Native American allies during the 1814 Battle of Mackinac Island, part of the War of 1812. Fort Holmes is the highest point on the island. Taken by photographer James Jenney and originally published as a stereoview.

Photo of a Preserved Section of Revolutionary War Era Fortifications at Valley Forge, Pennsylvania (1862)

 

 

"On the old fortification at Valley Forge." View of a section of Revolutionary War-era fortifications at Valley Forge, Pennsylvania, c. 1862. Taken by Amateur Photographic Exchange Club member Samuel Fisher Corlies. Originally published as a stereoview. I think that the trees look to bare for this to have been taken in May as the Library of Congress site states so probably the May date on the card only pertains to the printing date.
