Congressman Lincoln writes to Andrew McCallen, of Shawneetown Illinois, in response to McCallen's recent inquiry. Apparently, McCallen seeks to involve his "Regiment" in the war with Mexico. Lincoln advises McCallen that the United States may not need more troops because "[t]here is now some probablility of peace." Lincoln writes, "but, should the war go on, I think volunteers, with the right of electing their own officers will be voted, but that no more regulars, will be voted. Until Congress shall act, of course, nothing can be done towards getting your Regiment into the service. Whenever it shall act I shall be happy to assist you in any way I can." In a postscript, Lincoln adds, "Dont pay postage on letters to me. I am entitled to them free."Abraham Lincoln to Andrew McCallen, 4 February 1848, CW, 1:448-49.
