Glory Enough For All by Duane Schultz

This is a very good historical fiction book about the Battle of Petersburg during the Civil War.  Colonel Henry Pleasants is a mining enigineer serving with men from Pennsylvania who are coal miners in civilian life.  The lines of the Battle are not moving, so the men and and the colonel decide that they can help the Union Soldiers get to Petersburg by tunnelling under and blowing up Cemetery Hill.  This is a great idea and improves the men's morale, but the task will be accomplished without all the supplies they need.  General Burnside refuses to give them all the tools and explosives, so they improvise.  A huge explosion opens up the enemy lines.

The sad part of the story is that even after the lines are open, ineffectual leadership leads to the Union Army not taking advantage of the opening.  If the Union had taken the lead and used the huge hole, the War may have been over in 1864.  Instead, by not taking advantage, the war went on for another year.
