This Mexican-American War map depicts the positions occupied by the U.S. Troops and the Mexicans during the attacks in November and December 1847. Roads, topography, and a bird's-eye plan of the town are illustrated. An extensive numbered key identifies numerous locations on the map. Copied by Lieutenant W.H. Warner from a survey by H. Ehrenberg, and lithographed by P.S. Duval in Philadelphia.
Issued folding, now pressed, with a few spots of foxing, minor staining, and minor extraneous creasing.
