Career United States Army officer (1816–1864) who fought with distinction during the Mexican-American War, and also served as a Confederate general during the Civil War.

Walker, Brig Genl CSA,” one page, 8.25 x 9.75, Camp Jackson, February 18, 1862. Letter to a general. In part: “As there are many companies that have not their compliment of men would it not be better to fill them up to the legal number. Your order precludes enlistments but the law makes a company to consist of a certain number which number may have not. I have taken the liberty of mustering in those on hand and shall muster in those who arrive here who were en route when the order was published.” In very good condition, with small separations to horizontal folds, toning to edges, and spreading to ink.
