The Union's Army of the Tennessee attempts the storming of Vicksburg but is beaten back

After cutting off Vicksburg the day before, Union General U.S. Grant launched an immedate infantry assault on the city's defenses. Hoping that the Confederates were not prepared, Sherman's XV Corps attacked the Stockade Redan on the north side of the city.  More attacks in the afternoon from McClernand and McPherson's corps took place but all failed, with heavy casualties. Another, heavier attempt two days later also failed and a siege began. (By John Osborne)
