 The 6th Michigan Infantry’s final engagement came in an night assault on June 29, in which 35 Michiganders were ordered to storm the Citadel, one of the strongest fortifications at Port Hudson.Nine men were killed and eight wounded.Assistant Surgeon Milton Chase called the assault—ordered by habitually drunk division commander William Dwight (and remembered as the “whiskey charge”)—“a wicked loss of life.” The 6th Michigan, ravaged by battle losses and disease, mustered just 160 men and officers present for duty as of July 4.
