1917, Rutherford announced he had appointed four new directors to replace the four who had opposed him, claiming they had no legal status on the board because of conflict with Pennsylvania law. At the same meeting Rutherford surprised the headquarters staff and most of the directors by announcing the release of the book The Finished Mystery, dealing with the prophecies of the books of Revelation and Ezekiel and based on Russell's writings. The book, written by Bible Students Clayton J. Woodworth and George H. Fisher, was described as the "posthumous work of Russell" and the seventh volume of Studies in the Scriptures. It was an immediate best-seller and was translated into six languages. Rutherford and the ousted directors published a number of newsletters through 1917 and 1918 attacking each other and some congregations split into opposing groups of those loyal either to the president or those he had expelled. Rutherford staged a purge within the Brooklyn headquarters to force out those not wholeheartedly on his side and required those who remained to sign an oath of allegiance to him. He was re-elected as president in 1918 with a big majority, but by mid-1919 about one in seven Bible Students had left, forming such groups as The Stand Fast Bible Students Association, Laymen's Home Missionary Movement, Dawn Bible Students Association, Pastoral Bible Institute, Elijah Voice Movement and Eagle Society. Subscriptions to The Watch Tower also fell from 45,000 to fewer than 3000 between 1914 and 1918. Rutherford introduced a vast advertising campaign to expose the "unrighteousness" of religions and their alliances with "beastly" governments, expanding on claims in The Finished Mystery that patriotism was akin to murder. The campaign provoked anger among the clergy and governments in North America and Europe, where Bible Students began to be arrested, mobbed and tarred and feathered. On February 12, 1918, The Finished Mystery was banned by the Canadian government for what a Winnipeg newspaper described as "seditious and antiwar statements". On February 24 in Los Angeles Rutherford gave the first of his talk series "Millions Now Living May Never Die" (the title of the talk was changed five weeks later to "Millions Now Living Will Never Die") in which he attacked the clergy, describing them as "the most reprehensible men on earth for the great war that is now afflicting mankind". Three days later the Army Intelligence Bureau seized the Society's Los Angeles offices
