Military officer; born in
Philadelphia, March 16, 1802; graduated at
West Point in 1822; distinguished himself in the war in
Florida, and served in the war against
Mexico, in which he was assistant-adjutant-general with the rank of major, at the beginning.
Late in 1847 he was promoted to major of infantry: was made inspector-general in 1850; and in April, 1S53, resigned.
When the
Civil War broke out, he organized the
Pennsylvania Reserve Corps, consisting of 15,000 men, and was made brigadier-general in May, 1861.
This force was converted into three divisions of the Army of the Potomac, under his command, and they did gallant service in
McClellan's campaign against
Richmond in 1862.
Made captive on the day before the
battle of Malvern Hills, he suffered such rigorous confinement in
Richmond that he returned home in broken health, and resigned in March, 1863.
He died in
West Chester, Pa., Feb. 26. 1868.
