On September 16, 1862, one day before the historic Battle of Antietam, Major General George B. McClellan lost his best opportunity to defeat General Lee's army in detail in Maryland. McClellan was slow to assemble his forces in and around the town of Sharpsburg, Maryland. McClellan was unaware that he substantially outnumbers Lee's army and postpones an attack on the Confederates. Instead he waits another day until his reserve forces joins his main army. Theoretically, if McClellan conducted an assault on September 16, the Battle of Antietam would have been a smashing Union victory.

What was the costly error that General McClellan made on September 15 1862?

On September 15, 1862, Major General George B. McClellan made a miscalculation that would have made a significant impact on the Battle of Antietam. In fact, that battle would have taken place on that date instead of September 17, 1862. On the 15th McClellan could have attacked General Lee's forces at Sharpsburg but he hesitated. He believed he did not have enough troops, when in fact he had 40,000 troops as compared to Lee's 18,000 troops. Clearly, this would have changed the history of the US Civil War, and may have ended that war in a very short time, as Lee's army would have been devastated.
