In Louisiana, Confederate defenders of Port Hudson beat back an all-out Union assault
Union troops under General N.P. Banks had surrounded the Confederate stronghold on the Mississippi River the previous week and now mounted a full fledged attempt to storm its defenses in an attack starting at dawn. Generals Weitzel and Paine led the morning attacks and General W.T. Sherman made further assaults in the afternoon. All the attacks failed and Union losses were heavy, around 1800 total casualties. Confederate defenders reported less than fifty casualties. Banks settled in for a siege and Port Hudson finally surrendered on July 9, 1863. (By John Osborne)
