On January 1, Maj. Gen. “Stonewall” Jackson marched north in bitter cold from Winchester to Bath with the objective of disrupting traffic on the B&O Railroad and C&O Canal. On January 5, after skirmishing with the retiring Federals, Jackson’s force reached the Potomac River opposite the garrisoned town of Hancock, Maryland. His artillery fired on the town from Orrick’s Hill but did little damage. Union garrison commander Brig. Gen. F.W. Lander refused Jackson’s demands for surrender. Jackson continued the bombardment for two days while unsuccessfully searching for a safe river crossing. The Confederates withdrew and marched on Romney, in western Virginia, on January 7.

Hancock served in a number of assignments as an army quartermaster and adjutant, mostly in St.
Hancock returned east to assume quartermaster duties for the rapidly growing Union Army, but was quickly promoted to brigadier general on September 23, 1861, and given an infantry brigade to command in the division of Brig.
Hancock thus was in temporary command of the "left wing" of the army, consisting of the I, II, III, and XI Corps, which demonstrated Meade's high confidence in him, because Hancock was not the most senior Union officer at Gettysburg at the time.
At the battle of Antietam he was placed in command of the first division of the 2nd corps, and in November he was made major-general of volunteers, and about the same time was promoted major in the regular army.
The Battle of Gettysburg began on the 1st of July with the defeat of the left wing of the Army of the Potomac and the death of General Reynolds.
Hancock's superb presence and power over men never shone more clearly than when, as the 150 guns of the Confederate army opened the attack he calmly rode along the front of his line to show his soldiers that he shared the dangers of the cannonade with them.
