The Battle of Chancellorsville

Today was yet another victory for the Confederacy.  Though Lee's men were outnumbered terribly, Major General Joseph Hooker's failed battle plan proved that the South shall never surrender to the Union.  Both Jackson and Lee made some of the biggest stategy gambles so far, yet only Lee's seemed to be worth it.  Though this was known as his "greatest victory", the casualties say another thing.  Over 13,000 men had died during this battle, which counted for over 22% of Lee's army.
