28, with the company refusing to institute these changes, up to 1,000 of the mill's 1,200 workers went on strike and began picketing outside the plant. At the same time, messengers were sent to the logging camps throughout the area to convince the lumberjacks to strike, and over 2,000 did so between January 1 and 2. In its first few days, the strike was successful in partially shutting down Virginia and Rainy Lake's plant and several logging camps in the region, while a sawmill owned by the International Lumber Company in International Falls was also affected by a walkout. However, early on, lumber management began to work with local law enforcement agencies and public officials to break the strike. Strikebreakers were brought in from other areas of the state, while police arrested dozens of strikers and IWW leaders on questionable charges. Additionally, many local municipalities began to enact laws that outright banned the IWW from their jurisdictions, with members facing either expulsion or imprisonment. By mid-January, many of the local IWW leaders had been arrested, while striking lumberjacks began to abandon the strike. With the help of deputized sheriffs acting for the companies, many logging camps began to resume operations within a week of the initial lumberjack walkouts, and many mill workers began to return to work due to low strike pay. Finally, on February 1, the remaining leadership of Local 490 met in Duluth and declared the strike over. The IWW was able to claim a partial victory in the strike, as lumber companies instituted some changes to address the lumberjacks' poor working conditions and low pay. However, the strike had severely damaged Local 490's presence on the Mesabi Range, and while the IWW had planned to launch another organizing drive in the area, U.S. involvement in World War I and the accompanying suppression of the IWW by state and federal governments hurt these plans. In 1917, Minnesota enacted a criminal syndicalism law aimed in part at the IWW, and in September of that year, an IWW individual in Minnesota became the first person in the U.S. to be convicted under such a law. During the 1920s and 1930s, organizing efforts among lumber workers in the area would be taken over by the affiliate unions of the American Federation of Labor and the Committee for Industrial Organization. Discussing the strike in a 1971 article, historian John E. Haynes said,
