In Philadelphia, Mayor Alexander proclaims both against treason and popular disorder in the city
Mayor Alexander of Philadelphia made an official proclamation ordering that "all good citizens ... disclose and make known to the lawful authorities every person rendering in this city aid to enemies in open war against this State and the United States..." At the same time, he also banned "assembling in the highways of the city unlawfully, riotously, or tumultuously." The city had seen several violent demonstrations against people and businesses suspected of southern sympathies. (By John Osborne)
