U.S.10-inch Rodman gun, Model 1861
In 1867, the United States Army installed forty 10-inch Rodman cannons in the first and second tier casemates of Fort Point. These cannons were made using the newest technology, the Rodmand Process. In, 1893, soldiers fired a 17-gun salute to honor Vice President Adlai E. Stevenson during his visit to San Francisco. This may have been the last time Fort Point's Rodman cannon were ever fired.
