From the General himself

On May 2, 1863, General Thomas Jackson (nicknamed Stonewall) of the Confederate Army, was visited by Chaplain Lacy after losing his arm from a bullet wound accidentally shot by one of his own men.

You see me severely wounded but not depressed.....I am sure that my Heavenly Father designs this affliction for my good.  I am perfectly satisfied, that either in this life, or in that which is to come, I shall discover that what is now regarded as a calamity, is a blessing.....If it were in my power to replace my arm, I would not dare to do it, unless I could know it was the will of my Heavenly Father.
