papers. Rhetorical combat was a Patriot tactic that explained the issues of the day and fostered cohesiveness without advocating outright rebellion. The columnists spoke to the colonists as an independent people tied to Britain only by voluntary legal compact. The Spy soon carried radicalism to its logical conclusion. When articles from the Spy were reprinted in other papers, the country as a whole was ready for Tom Paine's Common Sense (in 1776). The turbulent years between 1775 and 1783 were a time of great trial and disturbance among newspapers. Interruption, suppression, and lack of support checked their growth substantially. Although there were forty-three newspapers in the United States when the treaty of peace was signed (1783), as compared with thirty-seven on the date of the battle of Lexington (1775), only a dozen remained in continuous operation between the two events, and most of those had experienced delays and difficulties through lack of paper, type, and patronage. Not one newspaper in the principal cities, Boston, New York, and Philadelphia, continued publication throughout the war. When the colonial forces were in possession, royalist papers were suppressed, and at times of British occupation, revolutionary papers moved away, or were discontinued, or they became royalist, only to suffer at the next turn of military fortunes. Thus there was an exodus of papers from the cities along the coast to smaller inland places, where alone it was possible for them to continue without interruption. Scarcity of paper was acute; type worn out could not be replaced. The appearance of the newspapers deteriorated, and issues sometimes failed to appear at all. Mail service, never good, was poorer than ever; foreign newspapers, an important source of information, could be obtained but rarely; many of the ablest writers who had filled the columns with dissertations upon colonial rights and government were now otherwise occupied. News from a distance was less full and regular than before; yet when great events happened, reports spread over the country with great rapidity, through messengers in the service of patriotic organizations. The quality of reporting was still imperfect. The Salem Gazette printed a full but colored account of the battle of Lexington, giving details of the burning, pillage, and barbarities charged to the British, and praising the militia who were filled with "higher sentiments of humanity." The Declaration of Independence was published by Congress, July 6, 1776, in the Philadelphia Evening Post, from
