The first Mayor of Pittsburgh, from 1816 to 1817.

A soldier during the American Revolutionary War whose journal is one of the most frequently quoted accounts of the surrender of the British at the siege of Yorktown.

Early life

Denny was born in Carlisle, Pennsylvania on March 11, 1761, the eldest son of William and Agnes Parker Denny. At the age of 13 he was entrusted to carry dispatches across the Allegheny Mountains by the commandant at Fort Pitt. He crossed alone often; to conceal his presence he hid in the woods at night. At one point he was chased into Fort Loudon by the Indians. He then entered into employment for his father's shop in Carlisle. Upon learning that a letter of the marque, a privateer ship, was to sail from Philadelphia for the West Indies, he shipped as a volunteer. He was promoted to command the quarter-deck for his gallantry in numerous sea fights.

Revolutionary War

As he was readying to sail on his second voyage he received a commission as ensign in the 1st Pennsylvania Regiment of the Continental Army in 1778. In August of 1780 he was transferred to the 7th Pennsylvania Regiment, and on May 23, 1781 he was promoted to lieutenant in the 4th Pennsylvania Regiment. Shortly thereafter he was promoted to captain.

This transpired during 1781 as the Continental Army marched south to face Cornwallis at Yorktown, Virginia, at which time the end of the long war for independence drew close. Near Williamsburg, Virginia, the regiment has a successful encounter against British forces, the partisan Simcoe. Denny in his famous military journal states, "Here for the first time saw wounded men; the sight sickened me."

As the Continental Army closed around the British stronghold at Yorktown, Captain Denny described the scene, "Army encamped on the banks of the James River; part of the French fleet in full view."

His journal entry dated September 14, 1781 continues into further detail of the encampment:

General Washington Arrived; our brigade was paraded to receive him. Officers all pay their respects. He stands in the door, takes every man by the hand; the offices all pass in, receiving his salute, and shake hands. This is the first time I have seen the General.

October 15, 1781, The siege at Yorktown begins:

Siege operations were at once commenced; the fighting became very warm on all sides, and the siege works were pushed with great vigor. Easy digging. light, sandy soil. A shell from one of French mortars set fire to a British frigate; she burned to the water's edge and then blew up; made the earth shake.

October 17, 1781, The Surrender of Cornwallis:

Had the pleasure of seeing a drummer mount the enemy's parapet and beat a parley and immediately an officer, holding up a white handkerchief, made his appearance. An officer from our line ran and met him and tied the handkerchief over his eyes, and thus was the great event of the surrender of Cornwallis accomplished.

Pittsburgh politics

Unlike other early pioneer towns and cities, the Commonwealth of Pennsylvania did not allow settlement to city without first being a council led "borough" for a number of years. Partly because of this, Denny instead started his political career in county government serving Pittsburgh.

In 1797 Denny was elected Allegheny County Commissioner, he eventually sought even higher office and ran successfully as Treasurer for the entire county in 1803 and 1808.

Being a Revolutionary War hero, and major patriot force for the frontier front of the War of 1812, Ebenezer ran successfully to become the first mayor of the "city" of Pittsburgh on July 19, 1816.
