A LIEUTENANT AT EIGHTEEN is the third of the series of The Blue and the Gray - on Land. The stirring events of thirty-four years ago, when the first gun of the Great Rebellion awoke the nation from its slumber of thirteen years of peace, transformed the older boys of the day into men. Thousands of them who lacked three or four years of their majority, and some of them even six or seven years of it, flocked to the standard of the imperilled Union. While the volunteers were in considerable numbers over the military age, those who were not yet out of their teens were earnest in their desire to be enrolled in the ranks of the loyal army, and in one way or another surmounted the obstacle of their tender age.
