My Brave Mechanics - The First Michigan Engineers and Their Civil War Hardcover

As volunteer engineers for the Union army, the First Michigan Engineers and Mechanics regiment was made up of skilled artisans, craftsmen, railroad men, and engineers whose behind-the-scenes work was crucial to the Union victory. Charged with maintaining the Union supply line in the western theater, the engineers constructed and repaired a staggering number of bridges, blockhouses, fortifications, railroads, and telegraph lines to keep the Union army functioning in the aftermath of battle.
