Pennock Huey Pennock Huey ( March 1 , 1828 – September 28 , 1903 ) was an officer and cavalry brigade commander in the Union Army during the American Civil War . Biography . Huey was the son of Jacob Huey , a farmer in Chester County , Pennsylvania known locally as " The Squire of Kennett Square " . He pursued a career as a merchant before war broke out in 1861 . In September 1861 , he became captain of Company D of the 8th Pennsylvania Cavalry ( 89th Pennsylvania Volunteers ) , serving under the regiment ' s colonel , David McMurtrie Gregg . Huey was promoted to major in January 1862 . When Gregg became a brigade commander , Huey took command of the regiment and subsequently led it at the Battle of Chancellorsville , serving in the brigade of Thomas Devin . The brigade , including the 8th Pennsylvania , remained with the main body of the army , missing the futile raid George Stoneman led into south central Virginia . Huey ' s command became involved in a collision with Confederate infantry , from which it was only possible to extricate his troops by giving the order to ; " Draw sabre and charge . " This encounter on a back road , which cost the regiment substantial losses , later was magnified into a full - scale charge for which Cavalry commander Alfred Pleasonton took credit , claiming he had explicitly ordered Major Peter Keenan to go head to head with Jackson ' s troops . The charge , during which Keenan was killed , was completely inadvertent ; the only way to extricate a column of cavalry from a narrow road thick with Confederate infantry . Later on the evening of the charge , " Stonewall " Jackson , while out scouting the area for the presence of Union troops , was inadvertently shot by South Carolina troops having mistaken him and his party for Union soldiers . After his failed raid , Stoneman was removed from command of the Cavalry Corps in the Army of the Potomac , being succeeded by Pleasonton . When the corps was reorganized later that month , Gregg took command of the new second division , mostly composed of his old division , the third . This new organization included the 8th Pennsylvania . Huey , meanwhile , had been promoted to colonel of the regiment on June 25 , 1863 . Huey took command of a brigade under Gregg in time for the Gettysburg Campaign . He was on detached duty during the Battle of Gettysburg protecting supply trains in Maryland , but he participated in the pursuit of the Confederate army . The brigade served under Hugh Judson Kilpatrick , not Gregg , during the pursuit . Huey returned to regimental command for most of the remainder of 1863 . He led his regiment under Philip Sheridan in the opening campaigns of 1864 . Huey commanded Gregg ' s rear guard during part of the retreat from Trevilian Station . He was captured at the Battle of Saint Mary ' s Church , June 24 , 1864 . Paroled on December 9 , 1864 at Camp Asylum , Columbia , South Carolina , after imprisonment in that state , Huey resumed his command . He was made a brevet brigadier general in March 1865 and was mustered out with his regiment at Richmond , Virginia , on August 11 , 1865 . After the war , Huey married Elizabeth Waln Wistar , daughter of Joseph Wistar of Philadelphia , worked as a merchant and in the canal industry . He wrote his account of the charge at Chancellorsville to reclaim the credit he thought his due , contradicting Pleasonton ' s account of the action . Huey died on his farm at the age of 75 and was buried in Philadelphia .
