The story centers on a Henry Fleming, the protagonist, who matures from the inexperienced soldier, to the more quiet mature man. Initially, Fleming believes war to be glorious and honorable -the perfect test for courage, and thus enlists for the Union army. However, after fleeing from his first battle, Fleming realizes his own cowardice. He encounters a tattered man, whom he abandons eventually and even witnesses his friend's death. Walking further, he notices a regiment after fighting, each having gone through the battle experience, and Fleming both admires and envies them. Guilty from avoiding fighting, Fleming arrives back at his camp with a gash in his head he receives accidentally from another Union soldier. As he is cared for among the other soldiers, his wound mistaken for a battle scar and ironically earns a reputation. In later battles, Fleming even becomes the flag bearer and leads his regiment in battles. Finally understanding that war is not all glory, he matures into the experienced veteran.
With a relatively simple plot to follow, Crane explores more in depth with Fleming's thoughts throughout the novel. From the initial desire for recognition to the final reverence of war, Crane masterfully details Fleming's emotions. Although Crane did not introduce, in detail, other characters, his focus on one character -Fleming - allows him to portray the thoughts of only one. This style is Impressionism, where Crane writes in third person limited perspective, following only the thoughts of one character. Through this character, Crane's own opinion about war shines through Fleming's discovery and realization about war.
With the animalistic imagery and descriptions with color, Crane's style perfectly matches Fleming's emotions at all times. In battle, Fleming is described as barbaric, a beast fighting for its survival. Crane uses this comparison to show his own opinion on war -that war only brings out the worst in men. Also, the usage of color to describe Fleming's current emotion is also prevalent throughout the story. For example, while Fleming is in battle, he is overcome with a "red rage" to destroy his opponent. While rage already demonstrates a fierce fury, red only emphasizes its passionate nature. The colors add on to the detail and intensity of each description, vitalizing each aspect of setting.
Although Crane never clearly defines the setting, other than that of a battlefield, the story is assumed to be set during the Civil War, and Fleming contributes to the Union Army. Crane himself had never fought in a battle, nor ever witnessed one, yet his amazing descriptions of the war scenery almost proves otherwise. Without ever experiencing a soldier's familiarity in an army, Crane is still able to capture the emotions of a young soldier so well. For this, Crane's style has often been commended.
Overall, The Red Badge of Courage depicts the story of a man, eager to participate in battles to prove his bravery and earn a reputation. Upon actually encountering warfare, however, the man learns his insignificance in the world, and a soldier's actual purpose -to defend his beliefs and country. Killing is not the actual courage but willing to die for the protection of others is the true courage. Crane develops Fleming's character gradually, and the reader fully experiences Fleming's transformation from innocence to the experienced.
