Boaz Manlove became a Justice of the Peace for Sussex County on March 20, 1767 and served in that office until April 10, 1773. He was also Sheriff of Sussex County during those years and was considered a member of the "court party" one of the political factions in the colony at the time.
It was as the struggle for Independence began that he achieved his greatest notoriety. He started on the patriot side. On July 23, 1774, he was a leader of a meeting protesting taxes and the Boston Port Act, and he was appointed to a committee established to provide relief to the Bostonians. This show of support for the patriot cause led to his becoming one of three men, one from each county, named to sign a 30,000 pound issue of paper currency by the Delaware Assembly.
He only signed about half of the issue before deciding to cast his fortunes with King George III. The Delaware Assembly ordered his arrest in February of 1777, but by that time he was already in hiding. After evading several efforts to arrest him, Manlove, with fellow Tories, Thomas Robinson and John F. Smyth, fled to the British ship "Preston" in the Delaware Bay in March 1777.
An "Act of Free Pardon and Oblivion" passed by the Delaware Assembly on June 26,1778, specifically exempted Boaz Manlove and 45 other Tories from pardon for their deeds. It also provided for state confiscation of their property and its sale to raise revenue for the American cause. His property was sold for 2000 pounds and he may have removed to Nova Scotia, along with other Loyalist exiles.
