The 1st Michigan Engineers and Mechanics Regiment was an engineer regiment that served in the Union Army during the American Civil War. There were only ten other similar regiments in the Union Army. The Michigan unit was one of three engineering regiments raised in 1861, the other two being Missouri (August 1861) and New York (September 1861). Engineering regiments are often left off of many Order of Battles, but their contribution to campaigns were vital from a logistics point of view; repairing/building railroads, bridges and blockhouses; and destroying enemy communication lines, railroads and bridges. Engineering units like the First Michigan were often caught up in attacks from enemy guerrillas and cavalry skirmishes.
