St. Clair Augustine Mulholland

Held Chancellorsville's picket line all night to save an army.

At Chancellorsville, St. Clair Mulholland spent the night doing the job that made a retreat possible: holding the enemy in check. Born in Lisburn, Ireland, on 1 April 1839, he emigrated with his family to Philadelphia in 1850 and later entered Pennsylvania militia service. During the Civil War he served with the 116th Pennsylvania Infantry and rose from field-grade command to receive brevet recognition as a major general.

On 4–5 May 1863, as a major of the 116th Pennsylvania Infantry, Mulholland commanded the picket line during the withdrawal from Chancellorsville. His men held the enemy through the night while the Army withdrew. The action brought him the Medal of Honor, presented on 26 March 1895.

Medal of Honor Citation (condensed)

While commanding the picket line at Chancellorsville, he held the enemy in check throughout the night and covered the Army's retreat.

After the war Mulholland returned to Philadelphia civic life. He served as the city's chief of police beginning in 1868, later became a United States pension agent, and preserved the history of his regiment in an 1899 book on the 116th Pennsylvania. He died in Philadelphia on 17 February 1910 and was buried in Old Cathedral Cemetery.
