Confederates.
Stonewall Jackson led a wild charge that took the Union troops completely off-guard.
About 4,500 men died for the Union side in the battle of Chancellorsville.
The casualties on the Union side were: 11,116 in killed and wounded, 5,676 in prisoners and missing.
The Federals (North) had 133000 effectives, the South, just over 60,000.
The First shot fired at the Battle of Lexington and Concord may have been fired by either side. After the shooting starts, fixing the blame makes very little difference.

Confederates fired on Ft. Sumter in Charleston Harbor.
The British fired the first shots of American Revolutionary War at Lexington, on April 18,1775.
in the first battle of bull run he broke his finger. but after the battle of chancellorsville he was shot with friendly fire and had to have his arm amputated. He died 10 days later of nemonia due to the amputation.
Unknown to this day, but recently I read a plausible theory about why the shot may have been fired. There was a tavern nearby, and it was against the rules to bring a loaded musket inside. The only way to unload a musket was to fire it. Someone may have stepped inside for a drink, firing his musket in the air first. I think it unlikely that the British would have fired first without orders, but some of the Colonials may have panicked and fired when they heard the first shot.
That neither side was ready for operations
There were two of them:Admiral Chester W. Nimitz (Battle of Midway -- the most important naval battle; inflicting irreparable damage on the Japanese.)General Douglas Mac Arthur (Battle of the Coral Sea -- It was the first naval battle in history in which neither side's ships sighted or fired directly upon the other.)
