Today is the anniversary of the Battle of Corinth (distinguished from the Siege of Corinth) that took place on October 3rd and 4th, 1862. Union forces under the command of Major General William Starke Rosecrans defeated Confederate forces under the command of Major General Earl Van Dorn.
These days Rosecrans, if he is remembered at all, is known for being the Union commander at the gigantic Battle of Chickamauga in September 1863, one of the major Union defeats of the war and the second-bloodiest battle of the entire war after Gettysburg. But up to that point he had actually been one of the most successful Union generals Lincoln had. I learned a great deal about him during my time at Stones River National Battlefield, where Rosecrans was also the Union commander.
