After learning the trade, he was commissioned as an officer. By his 20s, he commanded small sloops that sailed the North American coast between
Halifax and New York. He sailed as far as the
West Indies. He was a militant and influential agitator and earned a reputation for bravery and sought to limit the scope of Britain's authority in 1760. Another nickname that was bestowed upon him by British military engineer and cartographer
John Montresor, was the “Spawn of Liberty and Inquisition” which Montresor both passionately and derisively called him and his posse of vigilantes. British Vice Admiral Samuel Graves lists Sears as the “most active leaders and agitators of the rebellion. He was at the head of nearly every demonstration of mob violence in New York City. He partnered with
James DeLancey in opposition to the stamps and supported him in his 1768 election to the New York assembly. Sears and many of his followers were engaged in trade and demanded that trade continue without stamps. In 1766, Sears,
John Lamb and three others formed a
committee of correspondence to communicate with other Sons of Liberty groups in other provinces. After the Stamp Act was repealed the Sons of Liberty erected a
Liberty pole to celebrate. The liberty pole was a galling sight to the redcoats and a symbol of pride and defiance to the townsfolk. They were successful in preventing the landing of tea. In April 1774, they boarded the
Nancy and destroyed its tea. During the
Townsend Acts, Britain passed a
Tea Act in 1773 to ship tea directly to North America to help the East India Company, saving it from being taxed so it can come out of bankruptcy. Sears and his companions believed that the ruin of their commerce was inevitable if they did not succeed in preventing the sale of India Company tea in America. They were convinced that this could only be effected by total prohibition of English tea, since the Company would find ways of importing its tea to America by way of private merchants regardless. He was also worried Britain would soon try to make a monopoly of other goods in the colonies, threatening the welfare of the Sons of Neptune. Before the tea was to be sent to the colonies, Captain Sears and McDougall decided an opposition was needed and sought to unite all the
Sons of Neptune and Liberty with the merchants and tea-smugglers. The
Sons of Liberty and the Dutch smugglers had come together and sparked the "New Flame" described by
William Smith. As the tea approached the harbors of New York, Philadelphia, and Boston in early November the campaign began. The tea stood in the boats that were in the harbor and no one dared to remove them for fear of the tea being destroyed. Towards the end of November, McDougall from Sons of Liberty made a publication to be sent out to all harbors. "If any of the tea by any persons associated with the India Tea Company had accepted a commission to sell, land, or store the tea would be paid "an unwelcomed visit, in which they shall be treated as they deserve: by 'The Mohawks.'" Thus Sears and McDougall initiated the use of this distinctively American name to cover the identity of those who were ready to employ violence to block the operation of the Tea Act." Not long after, the
Boston Tea Party took place and the tea ships in Philadelphia and New York turned back to England for fear of their cargo. When in May 1774 news of the
Boston Port Act arrived, Sears and McDougall wrote a letter of support to Boston, without consulting anyone else, in addition to a British boycott, they proposed a ban on exports to the West Indies and called for a Continental Congress. Reaction in New York to the Boston Port Act was cautious and equivocal, there was a split with the DeLanceys on whether to proceed with nonimportantion.
Committee of Sixty On May 16, 1774, a meeting at the
Fraunces Tavern was called of the various factions. The Committee of Fifty was elected with
Isaac Low as its chairman. James DeLancey's faction was in the majority, with Sears and his Sons of Liberty in the minority. In 1774, he was a leading member of New York City's
Committee of Sixty. In a letter to the Boston
Committee of Correspondence he proposed a meeting of delegates from the principal towns. This proposal was initially disavowed by the Committee of Sixty, but later was ratified in a proposal for the meeting of the
First Continental Congress.
American Revolutionary War On April 15, 1775, he was arrested for his anti-British activities, but was rescued at the prison door by his supporters and paraded through the streets as a hero. When news of the
Battle of Lexington arrived, he and his followers seized the
arsenal at the Custom House on April 23, 1775. He was the
de facto commander of New York City until Washington's Army arrived in June, 1776. On November 20, 1775, Sears led a group of 80 citizens in apprehending Parson Seabury, Judge Fowler, and Lord Underhill. At some point the mob forced Fowler to write (or else they forged his name) an apology and a promise not to interfere with the
Second Continental Congress.
Post-war years After the British left New York City in 1783, he returned to the city installing himself in a mansion on the Bowling Green and reviving the
Sons of Liberty. By March, he was calling for the expulsion of any remaining Loyalists in the state by May 1. He and other members of the Sons of Liberty won enough seats in the
New York State Assembly in December, 1784 to enact a set of harsh anti-Loyalist laws. He was exposed for buying up soldier's payzari certificates at depressed prices and using them to speculate in forfeited Loyalist property. The public regarded this as the height of venality and cynicism. He was again elected to the assembly in 1786, but by then he was deeply in debt and he left the state to avoid arrest. ==Death==
