Huger was promoted to major on March 2, 1863. At first, he was second in command of a battalion of artillery led by Col. Edward Porter Alexander. Alexander welcomed Huger, describing him later as "my glorious &amp; beloved Frank Huger, who never shirked a care or danger or grumbled over a hardship in his life..." In that capacity, Huger served in the Battle of Chancellorsville, including bombarding federal lines from high ground at Hazel Grove on May 3, 1863. Huger was sent on May 4 to support the division of Maj. Gen. Richard H. Anderson in the Battle of Salem Church. His guns were among those that fired the last shots of the battle the next day, as the Union VI Corps retreated across the Rappahannock River. At the Battle of Gettysburg, Huger was involved in supporting the attack of Lt. Gen. James Longstreet's corps on the federal left on July 2. During July 3 Huger took immediate command of the guns as Alexander was assigned responsibility for the bombardment preceding Pickett's Charge.
