Henry Martyn Lazelle (1832-1917) was the only cadet in the history of the U.S. Military Academy to be suspended and sent back a year (for poor grades and bad behavior) and eventually return as Commandant of the Corps of Cadets. After graduating from West Point in 1855, he scouted with Kit Carson, was wounded by Apaches, and spent nearly a year as a "paroled" prisoner-of-war at the outbreak of the Civil War. Exchanged for a Confederate officer, he took command of a Union cavalry regiment, chasing Mosby's Rangers throughout northern Virginia. Due in part to an ingrained disposition to question the status quo, Lazelle's service as a commander and senior staff officer was punctuated at times with contention and controversy. In charge of the official records of the Civil War in Washington, he was accused of falsifying records, exonerated, but dismissed short of tour. As Commandant of Cadets at West Point, he was a key figure during the infamous court martial of Johnson Whittaker, one of West Point's first African American cadets. Again, he was relieved of duty after a bureaucratic battle with the Academy's Superintendent.

Of the roughly 3,500 volunteer regiments and batteries organized by the Union army during the American Civil War, only a small fraction has been studied in any scholarly depth. Among those not yet examined by historians was one that typified the western armies commanded by the two greatest Federal generals, Ulysses S. Grant and William T. Sherman. The Forty-fifth Illinois Volunteer Infantry was at Fort Donelson and Shiloh with Grant in 1862, with Grant and Sherman during the long Vicksburg campaign of 1862 and 1863, and with Sherman in the Meridian, Atlanta, Savannah, and Carolinas campaigns in the second half of the war. These Illinois men fought in several of the most important engagements in the western theater of the war and, in the spring of 1865, were present when the last important Confederate army in the east surrendered. The Forty-fifth was also well connected in western politics. Its unofficial name was the “Washburne Lead Mine Regiment,” in honor of U.S Representative Elihu B. Washburne, who used his contacts and influences to arm the regiment with the best weapons and equipment available early in the war. (The Lead Mine designation referred to the mining industry in northern Illinois.) In addition, …
