invasion. On October 10, Jackson was promoted to lieutenant general, being ranked just behind Lee and Longstreet and his command was redesignated the Second Corps. Before the armies camped for winter, Jackson's Second Corps held off a strong Union assault against the right flank of the Confederate line at the Battle of Fredericksburg, in what became a Confederate victory. Just before the battle, Jackson was delighted to receive a letter about the birth of his daughter, Julia Laura Jackson, on November 23. Also before the battle, Maj. Gen. J. E. B.

The men were eating and playing games in carefree fashion, completely unaware that an entire Confederate corps was less than a mile away. What
