ANSWER
About 50,000 troops, probably something less then 50,000, because some infantry and two battalions of artillery were left behind the lines to guard the Potomac's fords.
George McClellan
Major George B. McClellan received poor advice from his cavalry and from local citizens regarding the number of troops he would have to battle against at Sharpsburg, known better as the Battle of Antietam. McClellan believed that Stonewall Jackson commanded between 40 to 50,000 troops and were close to joining General Lee at Sharpsburg, who commanded 30,000 soldiers.McClellan's estimates were vastly off target. When the Battle of Antietam finally began on September 17, 1862, Lee's total number of troops were barely 39,000.
