It was not long before public sentiment began to make itself felt, and the first demonstration took place in Boston. Anthony Burns was a slave who escaped from Virginia and made his way to Boston, where he was at work in the winter of 1853-4. He was discovered by a United States marshal who presented a writ for his arrest just at the time of the repeal of the Missouri Compromise in May, 1854. Public feeling became greatly aroused. Wendell Phillips and Theodore Parker delivered strong addresses at a meeting in Faneuil Hall while an unsuccessful attempt to rescue Burns from the Court House was made under the leadership of Thomas W. Higginson, who, with others of the attacking party, was wounded. It was finally decided in court that Burns must be returned to his master. The law was obeyed; but Boston had been made very angry, and generally her feeling had counted for something in the history of the country. The people draped their houses in mourning and hissed the procession that took Burns to his ship. At the wharf a riot was averted only by a minister's call to prayer. This incident did more to crystallize Northern sentiment against slavery than any other except the exploit of John Brown, and this was the last time that a fugitive slave was taken out of Boston. Burns himself was afterwards bought from his master by popular subscription. He became a free citizen of Boston, and ultimately a Baptist minister in Canada.
