By the morning of January 5, the temperature had fallen to , where it would remain steady for the next three days. The Stonewall Brigade was brought up that morning, and Jackson aligned his men on Orrick's Hill across the flooded and ice-choked
Potomac River from Hancock. At 09:30,
Colonel Turner Ashby was sent across the river with a request for Lander to surrender; Jackson warned that he would shell and then capture the town if Lander refused. Upon meeting Lander, Ashby was instructed to tell Jackson to "bombard and be damned" and was given a written rejection of the offer. While Ashby returned to the Confederate lines, Lander ordered that civilians leave the town and assigned the
84th Pennsylvania Infantry Regiment to serve as a fire brigade in case the coming bombardment started any fires. The
110th Pennsylvania Infantry Regiment defended warehouses, and two pieces of artillery were positioned on a hill behind the town. The Confederate cannons opened fire at about 14:00, and a sporadic artillery duel which inflicted no casualties continued until dusk. A Confederate detachment under Colonel
Albert Rust destroyed a bridge over the
Big Cacapon River belonging to the
Baltimore and Ohio Railroad, while another detachment failed in an attempt to destroy a dam upriver from Hancock. While Jackson opened January 6 with a bombardment of Hancock by the Rockbridge Artillery, Lander still desired to take offensive action against Jackson. He asked Major General
Nathaniel P. Banks to either cross the Potomac in Jackson's rear or to send him reinforcements, with which Lander would attack the Confederates directly. Banks had ordered Brigadier General
Alpheus Williams's brigade to march towards Hancock on January 5, but sent the request for offensive action through Major General
George B. McClellan, who viewed it as too risky and rejected it. Later that day, Jackson attempted to cross the Potomac at Sir Johns Run, but was repulsed. Having damaged the telegraph lines in the area, Jackson abandoned the attempt to take Hancock on January 7 and withdrew. The exchanges of artillery fire had caused little damage. The
National Park Service estimates that the two sides combined suffered about 25 casualties during the fighting. ==Aftermath and preservation==
