When Matthew Brady wasn’t photographing Abraham Lincoln, he was taking some of the most iconic photographs of the Civil War. Here is an example from our Caleb Fiske Harris Collection on the Civil War & Slavery: a photograph of an ironclad, identified as “probably the Camonicus or the Onondaga, at anchor in the James river in the spring of 1864.” The photograph was laid into the Civil War diary of Manchester W. Weld.
