Philip Kearny

Philip Kearny Jr. (June 1, 1815 – September 1, 1862) was a United States Army officer, notable for his leadership in the Mexican–American War and American Civil War. He was killed in action in the 1862 Battle of Chantilly.
When the American Civil War broke out in 1861, Kearny returned to the United States and was appointed a brigadier general, commanding the First New Jersey Brigade, which he trained. The Army had been reluctant to restore his commission due to his disability, but the shocking Union defeat at the First Battle of Bull Run made them realize the importance of seasoned combat officers. His brigade, even after he left to command a division, performed spectacularly, especially at the Battle of Glendale.
He received command of the 3rd Division of the III Corps on April 30, 1862. He led the division into action at the Battle of Williamsburg and the Battle of Fair Oaks. At Williamsburg, as he led his troops onto the field, Kearny shouted (in a notable quote), "I'm a one-armed Jersey son-of-a-gun, follow me!" The general led the charge with his sword in hand, reins in his teeth. He is noted for urging his troops forward by declaring, "Don't worry, men, they'll all be firing at me!" His performance during the Peninsula Campaign earned him much respect from the army and his superiors. He disliked the commander of the Army of the Potomac, Maj. Gen. George B. McClellan, whose orders (especially those to fall back) he frequently ignored. After the Battle of Malvern Hill, which was a Union victory, McClellan ordered a withdrawal, and Kearny wrote:
I, Philip Kearny, an old soldier, enter my solemn protest against this order for retreat. We ought instead of retreating should follow up the enemy and take Richmond. And in full view of all responsible for such declaration, I say to you all, such an order can only be prompted by cowardice or treason.

Kearny is credited with devising the first unit insignia patches used in the U.S. Army. In the summer of 1862, he issued an order that his officers should wear a patch of red cloth on the front of their caps to identify themselves as members of his unit. The enlisted men, with whom Kearny was quite popular, quickly followed suit voluntarily. Members of other units picked up on the idea, devising their own insignia, and these evolved over the years into the modern shoulder patch. (Daniel Butterfield is credited with taking Kearny's idea and standardizing it for all corps in the Army of the Potomac, designing most of the corps badges.) Kearny was promoted to major general on July 4, 1862, in a blanket promotion of McClellan's corps and division commanders.[4]
Death
By the end of August 1862, General Kearny led his division at the disastrous Second Battle of Bull Run, which saw the Union Army routed and nearly destroyed by Gen. Robert E. Lee's Confederate Army of Northern Virginia. The Union army retreated toward Washington and fought with the pursuing Confederate corps under Stonewall Jackson on September 1, 1862, at the Battle of Chantilly. In a violent storm with lightning and pouring rain, Kearny decided to investigate a gap in the Union line. Responding to warnings of a subordinate, he said, "The Rebel bullet that can kill me has not yet been molded." Encountering Confederate troops, Kearny ignored a demand to surrender and, while he tried to escape on horseback, a "half dozen muskets fired" and he was shot with a Minié ball that entered his hip and came out his shoulder, killing him instantly. Confederate Maj. Gen. A.P. Hill, upon hearing the gunfire, ran up to the body of the illustrious soldier with a lantern and exclaimed, "You've killed Phil Kearny, he deserved a better fate than to die in the mud."
Kearny's body was borne to the rear after the Confederates realized that a general officer had been killed. Confederate soldiers quickly proceeded to strip Kearny's body of his coat, boots, pocket watch, papers, and other items of value. However, after it was realized who the deceased was, Robert E. Lee ordered all of his belongings returned over the objections of poorly clad soldiers who protested that a dead man no longer needed a warm coat and boots. Kearny's papers were given to Lee for examination, but they merely consisted of personal letters to his wife and contained no useful military documents; Lee quickly burned them. General Lee sent his body back to Union forces, with a condolence note.
