A commissioned officer in the
Pennsylvania Navy,
Commodore Hazelwood commanded all naval vessels of the Pennsylvania and Continental navies on the Delaware River. In the years before the American Revolution he commanded a number of ships including the
Susanna and Molly in 1753, the
Greyhound in 1762, the
Monckton in 1763, the
Sally in 1771 and the
Rebecca in 1774. The earliest known record of Hazelwood's service in the
American Revolutionary War is 1775. Hazelwood was appointed supervisor of building and management of fire-vessels in December, 1775, and by October 1776 was promoted to
Commodore in the Pennsylvania Navy.
Early Revolution During the Revolutionary War, Hazelwood played an important role in the planning of the various American river defenses. During the months prior to the British advance on Philadelphia he oversaw the development and construction of fire-vessels, which were used in conjunction with the many river obstructions,
Cheval de frise, that were also developed for use in the Delaware River. Hazelwood was soon promoted to
Commodore of both the Pennsylvania and Continental navies in the Delaware River some time in 1777 but the exact date is not known.
Philadelphia finally fell on September 26 and
Vice Admiral Howe and the British army entered the city, however they were low on ammunition and supply and had not established a naval supply route along the heavily defended Delaware River. In the days that followed the British began fortifying the shore surrounding the city and at the mouth of the
Schuylkill River, bringing in heavy guns and supplies. During October the American fleet engaged British naval vessels and gave support to American forts along the river. Hazelwood frequently ordered galleys to deter British ships away from Billingsport. Hazelwood's galleys kept up a disrupting fire while others patrolled the waters around Fort Mifflin. On October 9, Hazelwood's fleet of galleys attacked the British battery at Webb Ferry. Two days later, Hazelwood landed a body of militia on Carpenter's Island, assaulting the middle battery and capturing fifty men and two officers. A second assault on British batteries was attempted the next day but was met with heavy fire, causing the American vessels to withdraw after receiving heavy losses. On October 22 the British launched naval assaults on positions below the fort in concert with a ground assault on Fort Mercer. At this time the Marine Committee of Congress ordered Hazelwood and his second in command, Captain Charles Alexander, to take a small fleet of vessels and fire on British positions in and about Philadelphia. During the exchange of fire, the American frigate
USS Delaware, commanded by Alexander, received heavy damage and was run aground where Alexander, his crew and ship were soon captured. When the tide had risen the
Delaware was brought back to Philadelphia. On October 23, Hazelwood's
gunboats and
galleys maintained a harassing fire on British
men-of-war trying to dismantle river obstructions. In the process the British
ship of the line HMS Augusta, commanded by
Francis Reynolds grounded and mysteriously caught fire and blew up. The
sloop of war Merlin also grounded, forcing its crew to burn the vessel. On October 27 Washington advised Hazelwood that he should send a party to the waterfront at Philadelphia at night and burn the captured
Delaware but Hazelwood thought the prospect too risky and declined. Though the capture of the
Delaware was a major tactical loss, Hazelwood now realized that attacking British positions and vessels about Philadelphia with smaller vessels more suitable to river navigation was a feasible effort. During the weeks Hazelwood had engaged the British on the Delaware River he innovated and developed many naval riverine tactics and introduced the idea of small boat riverine warfare to the American navy. However, in the face of mounting British forces Hazelwood's fleet eventually proved too small to maintain an effectual fire while maintaining a defense for forts Mifflin and Mercer. Fort Mifflin, commanded by Lieutenant Colonel
Samuel Smith, was located on an island in the middle of this river and was a key point of defense for the Americans. The fortress, along with
Fort Mercer on the east bank, were the only obstacles preventing the British naval access to Philadelphia.
Vice Admiral Howe dispatched a message to Hazelwood requesting that he surrender the Pennsylvania fleet, allowing Howe and his fleet to control the Delaware Bay, where Hazelwood was allegedly promised a pardon from the King if he cooperated. Hazelwood refused the dubious offer, declaring that he would "defend the fleet to the last". The successful siege upon the stone and earthen fort required the prolonged bombardment by the fleet under the command of Admiral Howe, also involving land batteries, lasting from September 26 to November 16, 1777. The standoff and defense of the fort allowed time for Washington and the Continental Army to safely deploy for the
Battle of White Marsh and its subsequent withdrawal to
Valley Forge. Washington received warnings from Generals
Porter and
Lee, stationed on the
Schuylkill River at Philadelphia, that the British were making communication runs across the river at night using small boats. In a letter of November 4, Washington
advised Hazelwood to do all he could to stop the activity. Hazelwood's efforts to end the communications were a failure. Several days before the fall of the fort Washington dispatched another letter to Hazelwood inquiring about his status, urging that if at all possible to remain at his station with the fleet after the fort has fallen so as to hinder and prolong British operations long enough to allow the river to freeze over, preventing passage of supply ships into Philadelphia until the spring thaw. After weeks of almost constant bombardment from British ships and batteries and receiving extensive damage and heavy casualties, Fort Mifflin was finally abandoned on November 15, while the fort's flag was left there and remained flying. Capture of the fort was finally effected on November 16, leaving only Fort Mercer on the
Red Bank of New Jersey to defend the river. Two days later, with 7,000 British troops led by
General Cornwallis and with
General Howe's 1000 troops marching north to Fort Mercer, Hazelwood scuttled many of the smaller ships and galleys located there while Captain
Christopher Greene and the American garrison abandoned the fort on November 20 leaving it to the advancing British. Two days later General Washington called a Council of War, meeting with several of his generals on board one of Hazelwood's ships. During the assembly Washington's council recommended that Commodore Hazelwood lead the effort "with the first favorable wind", and get the American ships and supplies in the area safely up river just past
Burlington, New Jersey. On the night of the 21st Hazelwood and the American naval fleet managed to pass by the British who were busy securing their position in Philadelphia, with no shots fired by them to stop passage of Hazelwood and the American fleet. Soon after the fall of Forts Mifflin and Mercer Washington and other commanders sought an explanation about what led to their capture. Washington had sent
General Varnum to Fort Mifflin in November to quell the frequent command disputes between garrison and naval commanders with little success. Varnum faulted himself and offered his apologies to Washington. Hazelwood and Smith, already rivals, laid the blame on each other. Exchanges between the two became increasingly heated and bitter, while each embarked on campaigns in Congress and the Pennsylvania Council for the purpose of exonerating themselves of any shortcomings, while the blaming from both continued. At one point their exchanges became so heated that Varnum and other officers had to intervene to prevent a duel. In June 1778 the British were ordered to abandon Philadelphia and defend New York. In August The
Assembly of Pennsylvania decided that a large State navy was no longer necessary and recommended that most of its ships and supplies be disbanded. During the transition Commodore Hazelwood, who was the last to hold this rank, was discharged along with a number of other officers. Later that year Hazelwood became a member of a public committee chosen to meet in Philadelphia to raise money to help provide for the Army. In 1780 he became the Commissary of Purchases for the
Continental Army, considered an office of great trust and responsibility over the great sums of money involved.
Post Revolution On April 11, 1785, Hazelwood was selected to be one of the port wardens in Philadelphia. ==Later life==
