English: "Old Sacramento Cannon" captured by U.S. during the Mexican-American War in 1847 and taken to the Liberty Arsenal. The cannon was seized by pro-slavery forces in 1856 and fired during the Sacking of Lawrence in 1856. Anti-slavery forces captured it at Franklin, later in 1856. The cannon was damaged in 1896 when it was loaded with clay and straw and fired. It is at the Watkins Community Museum of History in Lawrence. This photo was when it was on loan at the Missouri State Capitol in September 2007. Photo by poster.
