The April 1865 Battle of Five Forks was a Union victory that led to the Union operations to break through the Confederate field fortifications protecting Petersburg. At Five Forks, the Union forces were led by Major General Phil Sheridan. In this battle the long time Union veteran, General Gouverneur Warren, was relieved of duty by his superior officer, Sheridan. Sheridan claimed that Warren had failed to properly understand that he needed to not sit and wait when there was an alignment problem between the Kellogg brigade and the Crawford division. No great harm was the result but Sheridan believed that only "good luck" saved the assault.After the war, a court if inquiry exonerated Warren from any errors. As an aside, the postwar general in chief, General Sherman disagreed with the court and wanted Warren punished.
