Another account of the conquest of Vicksburg by Union troops. The focus is mostly on General Grant: "Oh bully for our chief... Old Jeff is getting scared, Grant's getting bolder... Three cheers for Grant, and the Union forever!"
Every historical event in this song is described in the notes to "Victorious March"; see the notes to this song.
Although this is surely a composed song, the informant almost certainly had it from oral tradition. This shows in the names of the officers. He mentions, in addition to Grant, three generals: MacPherson (James B. McPherson, 1828-1864, one of Grant's corps commanders), Logan (John A. Logan, 1826-1886, a division commander), and "McClellan."
George B. McClellan, former commander of the Army of the Potomac, of course did not serve at Vicksburg. The reference, I think, must be to John A. McClernand (1812-1900), a politician who had become one of Grant's corps commanders in exchange for raising many of the troops used in the expedition. He was not particularly competent, and would later be relieved. - RBW
