Despite the string of defeats, the Union Army was not beaten but was dispirited. Morale was very low. Most of the army withdrew to positions north of the Potomac River to regroup. Confederate President Jefferson Davis wanted to end the war, which he believed he could do in one of several ways: Defeat the main force of the Union army, take Washington, DC, topple the Lincoln government, or gain recognition from major European powers. Davis ordered General Lee to cross the Potomac and put pressure on Washington. As the Confederate Army drew near to the capital, the Union army was quickly organized to engage and the two armies met near Sharpsburg, Maryland, along Antietam Creek.
