the Defenses of the Capital and the Line of Operations of
the United States Army under Major General Scott in August
and September 1847.... New York: J. & D.
Majors Lith., . Lithographed map with U.S. Army
routes in red. 65.9 x 50.0 cm (26 x 19-5/8 inches). A few
short tears and light uniform
With this large-scale map is the following government document: Report of the Secretary of War, Communicating...a Map of the Valley of Mexico, from Surveys.... Washington: SED11, 1849. 8vo, disbound. Garrett, The Mexican-American War 430-31. Haferkorn, p. 31. Tutorow 1632. In the accompanying document, cartographer M. L. Smith (Lieutenant of the Topographical Engineers) writes to J. J. Abert (Colonel Corps Topographical Engineers) paying homage to the accuracy of Baron Humboldts map of the Valley of Mexico and stating that it was the only one in which they placed confidence for moving troops in to capture the city. He remarks, however, that he believes that the present map is the first survey of the valley ever made by triangulation. His colleague, E. L. F. Hardcastle, supplements the report with memoirs of the march made in his journal as events occurred. This sparse but pithy report has excellent details on military engineering, and the map is a great one for collectors of both the Mexican-American War and the cartography of Mexico.
