James Adelbert Mulligan (June 30, 1830 – July 26, 1864) was colonel of the 23rd Illinois Volunteer Infantry Regiment in the Union Army during the American Civil War. On February 20, 1865, the United States Senate confirmed the posthumous appointment of Mulligan to the rank of brevet brigadier general of U.S. Volunteers to rank from July 23, 1864, the day before he was mortally wounded at the Second Battle of Kernstown, near Winchester, Virginia. He commanded the Federal forces at the First Battle of Lexington, and later distinguished himself in other engagements in the Eastern theater prior to his death in battle. Biography Early life James Mulligan was born June 30, 1830 in Utica, New York. His parents had immigrated from Ireland, and his father died when he was a child. His mother remarried a Michael Lantry of Chicago, Illinois, and moved there with her son, who later attended the St. Mary's on the Lake College of North Chicago. From 1852–54 Mulligan read law in the offices of Isaac N. Arnold, U.S. Representative from the city. He was admitted to the bar in 1856, and commissioned a second lieutenant in the "Chicago Shield Guards". Raising the Irish Brigade At the onset of the Civil War, Mulligan raised the 23rd Illinois Volunteer Infantry Regiment in 1861, which was locally known as the "Irish Brigade" (not to be confused with a New York unit by the same name). This unit included the "Chicago Shield Guards". In September 1861, he led his troops toward Lexington, Missouri, as word had been received that this vital river town would be attacked by the pro-Confederate Missouri State Guard under Major General Sterling Price. Battle of Lexington The First Battle of Lexington, often referred to as the "Battle of the Hemp Bales", commenced on September 13, 1861, when 12,500 soldiers of the Missouri State Guard began a siege of Mulligan's diminutive command (only 3,500 in all), entrenched around the town's old Masonic College. On September 18, Price's army mounted an all-out assault on Mulligan's works, which failed. Cannon fire continued throughout the 19th. On the 20th, units of Price's army used hemp bales soaked in the Missouri River as a moving breastworks to work their way up the river bluffs toward Mulligan's headquarters. By 2:00 p.m., Mulligan had surrendered. Combined casualties were 64 dead, and 192 wounded. Price was reportedly so impressed by Mulligan's demeanor and conduct
