It was a defeat for Lee and the Confederates because his risky strategy of dividing his army in the presence of the enemy backfired.
One of his officers lost a set of orders in the field, where they were found by Union troops and shown to their commander McClellan, who realised that he could destroy Lee's divisions one by one.
However McClellan did not move quite fast enough to accomplish this, and also a Confederate spy in the camp had been able to alert Lee about the situation.
McClellan still defeated Lee, but Lee was able to get his army back to Virginia, to fight another day, very soon and with great effect.
The battle was known as the Battle of Sharpsburg to the Southerners.
It led Lincoln to declare the end of slavery in the South.
